This was an observational, retrospective study in patients seen between 2017 and 2021. Results. A total of 769 patients were studied. Dog bite injuries accounted for 5.6% of emergency visits and 0.8% of hospitalizations. They were more frequent in children younger than 5 years (55.1%), in whom the following were observed: greater injury severity (p = 0.008), history of animal provocation (p = 0.048), known attacking animal (p < 0.036), domestic accident (p = 0.021), greater frequency of post-exposure prophylaxis with anti-rabies serum (p = 0.005), and maxillofacial area as the main region involved (p < 0.001). There were 3 deaths due to human rabies and 1 due to hypovolemic shock. Conclusion. Dog bite injuries are a frequent cause of visit to the emergency department and hospitalization in pediatrics and have specific characteristics in children younger than 5 years.

Comparison of strip meniscometry and Schirmer tear test results and tear film breakup time between healthy dogs and dogs with dry eye disease / Comparação entre o teste de meniscometria em tira, o teste lacrimal de Schirmer e o tempo de ruptura do filme lacrimal em cães normais e com olho seco

ABSTRACT Purpose: To compare strip meniscometry and Schirmer tear test 1 results and tear film breakup time between dogs with normal eyes and dogs diagnosed with keratoconjunctivitis sicca. Methods: One-hundred fifty-six eyes of 78 dogs, 88 normal eyes, and 68 eyes diagnosed with keratoconjunctivitis sicca were included in the study. The tests were performed in the following sequence: Schirmer tear test 1 was used to allocate the dogs to the normal or keratoconjunctivitis sicca group, followed by the strip meniscometry test and tear film breakup time measurement. Results: The results (mean ± standard deviation) of the tests in the normal group were as follows: Schirmer tear test 1, 22.75 ± 3.88 mm/min; strip meniscometry test, 10.01 ± 2.35 mm/5 sec; and tear film breakup time, 25.82 ± 5.47 sec. In the keratoconjunctivitis sicca group, the results were as follows: Schirmer tear test 1, 6.10 ± 4.44 mm/min; strip meniscometry test, 3.03 ± 2.62 mm/5 sec; and tear film breakup time, 10.78 ± 4.23 sec. The Spearman correlation coefficient in the keratoconjunctivitis sicca group was very high, with a significant difference between the strip meniscometry test and Schirmer tear test 1 (r=0.848, p<0.001), and moderate and significant between the strip meniscometry test and tear film breakup time (r=0.773, p<0.001). The cutoff for the strip meniscometry test for keratoconjunctivitis sicca was 7.0 mm/5 sec. Keratoconjunctivitis sicca was suspected when the values were <10 mm/5 sec. Conclusions: This study provided strip meniscometry test values from dogs with normal eyes and eyes with keratoconjunctivitis sicca, with high sensitivity and specificity compared with those of the Schirmer tear test 1. In the future, the strip meniscometry test may be another important quantitative test and could complement the gold standard Schirmer tear test for the diagnosis of keratoconjunctivitis sicca in dogs, an excellent animal model for the study of the disease.

RESUMO Objetivo: Comparar o teste de meniscometria em tira com o teste lacrimal de Schirmer 1 e o tempo de ruptura do filme lacrimal, em cães com olhos normais e cães com diagnóstico de ceratoconjuntivite seca. Métodos: Cento e cinquenta e seis olhos de 78 cães, 88 olhos normais e 68 olhos com diagnóstico de ceratoconjuntivite seca. Os testes foram realizados na seguinte sequência: o teste lacrimal de Schirmer 1 foi utilizado para alocar os cães no grupo normal ou no grupo ceratoconjuntivite seca, seguido pelo teste de meniscometria em tira e tempo de ruptura do filme lacrimal. Resultados: As médias e desvios-padrão para os olhos normais foram: teste lacrimal de Schirmer 1 = 22,75 ± 3,88 mm / min; teste de meniscometria em tira = 10,01 ± 2,35 mm / 5 seg; tempo de ruptura do filme lacrimal = 25,82 ± 5,47 seg; e para os olhos do grupo ceratoconjuntivite seca foram: teste lacrimal de Schirmer 1 = 6,10 ± 4,44 mm / min; teste de meniscometria em tira = 3,03 ± 2,62 mm / 5 seg; tempo de ruptura do filme lacrimal = 10,78 ± 4,23 seg. O teste de correlação de Spearman no grupo ceratoconjuntivite seca foi muito alto, com diferença significativa entre teste de meniscometria em tira e teste lacrimal de Schirmer 1 (r=0,848, p<0,001), moderada e significativa entre teste de meniscometria em tira e tempo de ruptura do filme lacrimal (r=0,773, p<0,001). O cut-off para teste de meniscometria em tira para ceratoconjuntivite seca foi identificado em 7,0 mm / 5 seg, valores abaixo de 10 mm / 5 seg podem ser considerados suspeitos para KCS. Conclusões: Este estudo forneceu valores de teste de meniscometria em tira em olhos normais e com ceratoconjuntivite seca em cães, revelando alta sensibilidade e especificidade em comparação com o teste lacrimal de Schirmer 1. No futuro, o teste de meniscometria em tira pode ser outro teste quantitativo importante e pode complementar o teste lacrimal de Schirmer padrão ouro para o diagnóstico de ceratoconjuntivite seca em cães, um excelente modelo animal para o estudo de ceratoconjuntivite seca.

A Study of Clinico-social Profile of Animal Bite Patients Attending the Antirabies Clinic of BRD Medical College, Gorakhpur

Background: Rabies is one of zoonotic viral disease, estimated to cause 59000 human deaths annually in over 150 countries, of which 20,000 are from India alone; about 40% of which are in children under the age of 15. Rabies though 100% fatal is preventable with post-exposure prophylaxis which includes wound washing, anti-rabies vaccination and rabies immunoglobulin. Objective: To describe the clinico-social profile of animal bite patients attending the anti-rabies clinic of BRD Medical College, Gorakhpur. Methodology: A cross-sectional study was conducted in the anti-rabies clinic of Nehru hospital, BRD Medical College, Gorakhpur from January 2022 to May 2022. Study participants were interviewed by using a pre-phrased, pre-designed and pre-tested questionnaire. Data regarding socio-demographic and clinical profile of the study participants following animal bite exposure was collected. Results: The total number of animal bite victims were 250, in which majority of them were males (76.77%) and highest percentage was of adult population (20-59 years). Maximum number of victims were from rural area (78.70%). 19.35% were working and 39.35% were students. 77.43% were category III bites and in 50.96% cases lower limb was the site of bite and dogs were responsible for 89.67% of the bites. 60.64% victims did not wash the wound properly before reaching the anti-rabies clinic. Conclusion: This study concludes that as majority of the animal bite victims were students and majority of victims were unaware about the importance of wound care, therefore a step can be taken to create awareness in various schools.

Utilização da cannabis sativa para tratamento de dor crônica em cães / Use of cannabis sativa for the treatment of chronic pain in dogs / Uso de cannabis sativa para el tratamiento del dolor crónico en perros

A Cannabis sativa é uma planta que apresenta vários benefícios terapêuticos para animais, como tratamento da dor neuropática, inflamatória e osteoartrose. A dor é bastante recorrente na rotina clínica, sendo importante seu manejo para que seja ofertada uma melhor qualidade e conforto de vida para o paciente. O estudo objetivou identificar, a partir de evidências científicas, as características da utilização medicinal do uso de Cannabis Sativa no tratamento da dor crônica no cão, utilizando um dos seus princípios ativos, canabidiol (CBD). Foi feito uma revisão bibliográfica onde foi realizada a busca de estudos experimentais e relatos de caso em bases de dados eletrônicos, sendo incluídas fontes contendo a utilização do CBD em animais, que abordaram controle da dor, assim como escore avaliativo da dor antes, durante e após o tratamento proposto. Após eleger e analisar 54 estudos percebe-se que na medicina veterinária o uso do canabidio é insuficiente, uma vez que o foco da maior parte dos estudos clínicos é voltado para medicina humana. Ainda assim, a utilização de CBD mostrou-se eficaz, confirmando uma nova alternativa para o controle da dor em animais.(AU)

Cannabis sativa is a plant that has several therapeutic benefits for animals, such as the treatment of neuropathic and inflammatory pain and osteoarthritis. Pain is quite recurrent in the clinical routine, and its management is important to offer a better quality and comfort of life for the patient. The study aimed to identify, based on scientific evidence, the characteristics of the medicinal use of Cannabis Sativa in the treatment of chronic pain in dogs, using one of its active principles, cannabidiol (CBD). A bibliographical review was carried out in which experimental studies and case reports were searched in electronic databases, including sources containing the use of CBD in animals, which addressed pain control, as well as pain assessment score before, during and after the proposed treatment. After choosing and analyzing 54 studies, it is clear that in veterinary medicine the use of CBD is few, and the focus of clinical studies is on human medicine. The use of CBD proved to be effective, thus confirming a new alternative for pain control in animals.(AU)

Carcinoma de células escamosas (cce) em cão na região prepucial: relato de caso / Squamous cell carcinoma (scc) in dog in the preputial region: case report / Carcinoma de células escamosas (cce) en perro de la región prepucial: reporte de un caso

A expectativa de vida dos animais de companhia vem aumentando devido as mudanças comportamentais e de cuidados dos tutores. Em analogia, com as idades cada vez mais avançadas, é comum o desenvolvimento de doenças associadas, sendo o tumor o mais comum entre elas. Todavia, as neoplasias mais comuns na clínica de pequenos animais estão associadas ao sistema tegumentar. O carcinoma de células escamosas (CCE), ou carcinoma espinocelular, é uma neoplasia de epitélio, maligno, de crescimento lento e de baixo potencial metastático. Sua etiologia ainda não é precisamente conhecida e a causa exógena mais comum e descrita pela literatura é a exposição à luz ultravioleta, gerando consequentes lesões nas estruturas genéticas e imunogênicas na pele. Além disso, essas lesões apresentam-se de forma mais comum em animais de pelagem clara, com grande exposição solar e em área anatômicas hipopigmentadas. O prognóstico varia de acordo com a localização e o estágio clínico, sendo favorável o diagnóstico realizado precocemente, e o tratamento consiste na avaliação clínica seguida do protocolo adequado O presente relato de caso tem como objetivo principal reunir e discutir informações associadas sobre o carcinoma de células escamosas em caninos e felinos, abordando aspectos clínicos e patológicos, a fim de facilitar o raciocínio sobre o CCE, desde sua abordagem inicial, até seu diagnóstico final e estadiamento.(AU)

The life expectancy of companion animals has been increasing due to behavioral and care changes of the guardians. In analogy, with the increasingly advanced ages, the development of associated diseases is common, the tumor being the most common among them. However, the most common neoplasms in the small animal clinic are associated with the integumentary system. Squamous cell carcinoma (SCC), or squamous cell carcinoma, is a malignant, slow-growing, low-potential metastatic epithelial neoplasm. Its etiology is not yet precisely known and the most common exogenous cause described by the literature is exposure to ultraviolet light, generating consequent lesions on the genetic and immunogenic structures in the skin. In addition, these lesions are more common in light-haired animals, with high exposure to the sun, and in hypopigmented anatomical areas. The prognosis varies according to the location and clinical stage, being favorable to the early diagnosis, and the treatment consists in the clinical evaluation followed by the appropriate protocol. The present case report has as its main objective to gather and discuss associated information about squamous cell carcinoma in canines and cats, addressing clinical and pathological aspects, in order to facilitate the reasoning about the CCE, from its initial approach, to its final diagnosis and staging.(AU)

La esperanza de vida de los animales de compañía ha ido en aumento debido a los cambios de comportamiento y cuidado de los guardianes. Por analogía, con las edades cada vez más avanzadas, el desarrollo de enfermedades asociadas es común, siendo el tumor el más común entre ellos. Sin embargo, las neoplasias más comunes en la clínica de animales pequeños se asocian con el sistema tegumentario. El carcinoma epidermoide (CCE), o carcinoma epidermoide, es una neoplasia epitelial metastásica maligna de crecimiento lento y bajo potencial. Su etiología aún no se conoce con precisión y la causa exógena más común descrita por la literatura es la exposición a la luz ultravioleta, generando lesiones consecuentes en las estructuras genéticas e inmunogénicas de la piel.

Toxoplasma gondii and Neospora caninum antibody seroprevalence and risk factors among dogs treated at Public Veterinary Hospitals in São Paulo, Brazil / Soroprevalência de anticorpos anti-Toxoplasma gondii e Neospora caninum em cães atendidos em Hospitais Públicos Veterinários em São Paulo, Brasil

Abstract Dogs can be infected by Toxoplasma gondii and Neospora caninum, for which they function, respectively, as intermediate, and definitive hosts. In the present study seroprevalence against T. gondii and N. caninum antibodies, were determined by indirect fluorescent antibody test (cut off of 16 and 50, respectively), in dogs that were treated at public veterinary hospitals in the metropolitan region of São Paulo and risk factors were identified. Out of the 1,194 samples 125 (10.5%; 95% CI: 8.8-12.3%) were positive for T. gondii and 9 (0.75%, 95% CI: 0.34-1.4%) for N. caninum. For T. gondii, statistical differences were observed between the proportions of positive dogs and different zones of the municipality (p = 0.025), and age (p = 0.02), higher among older dogs. The keepers were invited to answer an epidemiological questionnaire to analyze risk factors, and 471 (39.4%) agreed to be interviewed, and among their dogs 65 (13.8%) were T. gondii seropositive. Age group above 8 years (OR = 3.63; 95% CI: 1.08-12.23) was a risk factor and having a defined breed (OR = 0.49; 95% CI: 0.25-0.96) was a protective factor for T. gondii infection. Because of the low number of dogs positive for N. caninum, risk factors for this coccidium were not determined.

Resumo Cães podem ser infectados por Toxoplasma gondii e Neospora caninum, os quais funcionam, respectivamente, como hospedeiros intermediários e definitivos. Neste estudo, a soroprevalência contra anticorpos anti-T. gondii e N. caninum foi determinada pelo teste de imunofluorescência indireta (ponto de corte de 16 e 50, respectivamente), em cães atendidos em hospitais públicos veterinários da região metropolitana de São Paulo e fatores de risco foram identificados. Das 1.194 amostras, 125 (10,5%; IC 95%: 8,8-12,3%) foram positivas para T. gondii e 9 (0,75%, IC 95%: 0,34-1,4%) para N. caninum. Para T. gondii foram observadas diferenças entre as proporções de cães positivos e diferentes zonas do município (p = 0,025) e idade (p = 0,02), prevalência maior entre os mais velhos. Os tutores foram convidados a responder um questionário epidemiológico para análise de fatores de risco, e 471 (39,4%) concordaram em ser entrevistados, destes 65 cães (13,8%) eram soropositivos para T. gondii. Faixa etária acima de 8 anos (OR = 3,63; IC 95%: 1,08-12,23) foi fator de risco e raça definida (OR = 0,49; IC 95%: 0,25-0,96) foi fator de proteção para a infecção por T. gondii. Devido ao baixo número de positivos para anticorpos anti-N. caninum, fatores de risco para este coccídio não foram determinados.

Prevalence and risk factors associated with canine dermatophytoses among dogs in Kwara and Osun States, Nigeria

Background: Dermatophytosis (ringworm) is a zoonotic fungal skin infection caused predominantly by Microsporum canis, Microsporum gypseum and Trichophyton spp. It is highly transmissible and, while normally self-limiting, could be problematic due to its potential to cause disease in certain human populations. The occurrence and associated risk factors of dermatophytoses in dogs presented at three veterinary clinics in Osogbo, and Ilorin, Nigeria between July and November 2019 were investigated in this study. Methodology: This was a descriptive cross-sectional study of 325 dogs with lesions suggestive of dermatophytosis, selected by simple random sampling from veterinary clinics of two hospitals, purposively selected for the study due to high patronage of the veterinary hospitals by dog owners. Using conventional mycological sampling techniques, plucked hairs and skin scrapings were obtained the dogs. The samples were emulsified in 10% potassium hydroxide, examined microscopically for fungal elements and cultured using standard mycological procedures. Information on dog demographic characteristics and risk factors for dermatophytosis were collected using structured questionnaire. The association between risk factors and demographic variables with the occurrence of dermatophytoses was determined using Chi-square test (with Odds ratio and 95% confidence interval) and p value < 0.05 was considered statistically significant. Results: Positive cultures for dermatophytes were obtained from samples of 48 (14.8%) dogs with M. canis 37.5% (18/48), M. gypseum 27.0% (13/48) and T. mentagrophytes 8.3% (4/48). Other fungi identified were Aspergillus flavus 12.5% (6/48) and Malassezia canis 12.5% (6/48). The age distribution of positive dogs were < 1 year (50.0%, n=24), 1-3 years (29.2%, n=14) and > 3 years (20.8%, n=10), while the risk factors associated with dermatophytosis included sex of dogs (p=0.0428), history of dermatophytosis (p<0.0001), clinical presentation (p<0.0001) and lesion type, especially kerion and pustular lesions (p=0.0297). Conclusion: These findings established the occurrence of dermatophytosis in dogs kept for companionship (i.e., pets), security and breeding purposes in one northern and southern States of Nigeria. Our findings underscore the need for routine mycological investigations in dogs to facilitate early detection of cases and prompt institution of treatment interventions, thereby preventing zoonotic transmission of dermatophytes to their owners, handlers and veterinarians.

Biomechanical evaluation of four surgical techniques for ventral stabilization of the atlantoaxial joint in dogs

ABSTRACT Purpose: This study compared, through biomechanical evaluation under ventral flexion load, four surgical techniques for ventral stabilization of the atlantoaxial joint in dogs. Methods: In total, 28 identical atlantoaxial joint models were created by digital printing from computed tomography images of a dog, and the specimens were divided into four groups of seven. In each group, a different technique for ventral stabilization of the atlantoaxial joint was performed: transarticular lag screws, polyaxial screws, multiple screws and bone cement (polymethylmethacrylate-PMMA), and atlantoaxial plate. After the stabilization technique, biomechanical evaluation was performed under ventral flexion load, both with a predefined constant load and with a gradually increasing load until stabilization failure. Results: All specimens, regardless of stabilization technique, were able to support the predefined load without failing. However, the PMMA method provided significant more rigidity (p ≤ 0.05) and also best resisted the gradual increase in load, supporting a significantly higher maximum force (p ≤ 0.05). There was no statistical difference in flexural strength between the transarticular lag screws and plate groups. The polyaxial screws method was significantly less resistant to loading (p ≤ 0.05) than the other groups. Conclusions: The PMMA technique had biomechanical advantages in ventral atlantoaxial stabilization over the other evaluated methods.

Occurrence of gastrointestinal parasites in dogs in a rural area of Santa Catarina, Brazil / Ocorrência de parasitas gastrintestinais em cães de área rural de Santa Catarina, Brasil

Abstract We investigated the occurrence of gastrointestinal parasites in dogs in rural areas of the municipality of Painel, Santa Catarina, Brazil. For this, 91 canine feces samples were collected from 82 farms between August, 2017 and January, 2018. These fecal materials were processed using the techniques of spontaneous sedimentation, centrifugation-floatation in zinc sulfate and Ziehl-Neelsen staining. A questionnaire in the form of an interview was administered to the dogs' owner and information about the farm and the main care provided for the dogs was obtained. Among 91 sampled dogs, 27 (29.7%) were positive for at least one parasite species. Ancylostoma was the most prevalent genus (16.5%), followed by Giardia duodenalis (14.3%), Trichuris vulpis (6.6%), Toxocara canis (5.5%), Entamoeba spp. (4.8%), Cryptosporidium spp. (3.3%) and Taeniidae (1.1%). Most dogs do not receive veterinarian care and rarely received antiparasitic treatment. They were free to roam and had free access to animal remains and garbage, which was reflected in the significant associations with the occurrence of parasites that were found. We conclude that rural dogs harbor gastrointestinal parasites, but that their owners are unaware of the risks that these parasites can bring to human health.

Resumo Foi investigada a ocorrência de parasitos gastrintestinais com potencial zoonótico, em cães de área rural do munícipio de Painel, Santa Catarina, Brasil. Para isso, foram colhidas amostras de fezes de 91 cães de 82 propriedades rurais, no período de agosto de 2017 a janeiro de 2018. Este material fecal foi processado pelas técnicas de sedimentação espontânea, centrífugo-flutuação em sulfato de zinco e coloração pelo Ziehl-Neelsen. Um questionário em forma de entrevista foi aplicado aos tutores dos cães e foram obtidas informações sobre a propriedade rural e principais cuidados com os cães. Entre as 91 amostras de fezes, em 27 (29,7%) foi detectada a presença de parasitos gastrintestinais, sendo Ancylostoma o gênero mais prevalente (15 / 16,5%), seguido por Giardia duodenalis (13 / 14,3%), Trichuris vulpis (6 / 6,6%), Toxocara canis (5 / 5,5%), Entamoeba spp. (4 / 4,8%), Cryptosporidium spp. (3 / 3,3%) e Taeniidae (1 / 1,1%). A maioria dos cães não recebia cuidados veterinários ou antiparasitários. Concluiu-se que os cães de área rural albergam parasitos gastrintestinais, porém seus tutores desconhecem os riscos que esses parasitos podem trazer para a saúde humana.

Isolation of Escherichia coli and Klebsiella pneumoniae strains producing extended-spectrum ß-lactamases from dog urine of the Metropolitan Area of the Aburrá Valley (Antioquia, Colombia) / Aislamiento de Escherichia coli y Klebsiella pneumoniae productoras de betalactamasas de espectro extendido a partir de orina de perros del Área metropolitana del Valle de Aburrá (Antioquia, Colombia)

ABSTRACT Escherichia coli and Klebsiella pneumoniae are the most common pathogens causing urinary tract infections in humans and animals. Close contact between humans and companion animals can facilitate the spread of multidrug resistant pathogens between both species. The objective of the research was to characterize extended-spectrum ß-lactamases (ESBL) -producing E. coli and K. pneumoniae isolated from dogs with urinary tract infections in the metropolitan area of Valle del Aburrá (Antioquia, Colombia). Three-hundred seventy-one urine samples collected from March 2018 to March 2019 in a veterinary clinical laboratory were analyzed. E. coli and K. pneumoniae isolates were detected in chromogenic agar and identified by biochemical tests. Susceptibility testing was performed by disc diffusion and ESBL production was evaluated by the double disk test in all isolates. MIC determination of ESBL-positive isolates were performed on the automated VITEK®2 system. Multiple PCR was used for the detection of CTX-M beta-lactamases (group 1, 2, 9 and 8/25), SHV, TEM, and AmpC of plasmid origin in ESBL-positive isolates. In total 22 out 371 isolates were positive for ESBL production by double disc test, 11 E. coli (ESBL-Ec) and 11 K. pneumoniae (ESBL-Kp). The multiple PCR detected CTX-M group 1 in the 22 ESBL-positive isolates. Multi-drug resistance was observed in all ESBL-producing isolates. In conclusion, a high frequency of antibiotic multi-resistance was found in ESBL-Ec and ESBL-Kp. The main ESBL detected was CTX-M group 1, which also prevails in human isolates.

RESUMEN Escherichia coli y Klebsiella pneumoniae son los patógenos más comunes causantes de infecciones en tracto urinario en humanos y animales. El contacto estrecho con los animales de compañía puede favorecer la diseminación de patógenos multiresistentes entre ambas especies. El objetivo de la investigación fue caracterizar E. coli (Ec -BLEE) y K. pneumo-niae (Kp -BLEE) productores de betalactamasas de espectro extendido provenientes de aislados de caninos con infecciones del tracto urinario del Área Metropolitana del Valle de Aburrá. 371 muestras de orina de caninos colectadas entre marzo de 2018 y marzo 2019 en un laboratorio clínico veterinario fueron analizadas. E. coli y K. pneumoniae se detectaron en agar cromogénico y se identificaron mediante pruebas bioquímicas. La prueba de susceptibilidad se realizó por difusión en disco y la producción de BLEE se evaluó por test de doble disco en todos los aislados. La determinación de la CIM en aislados positivos a BLEE se realizó en el sistema automatizado VITEK®2. Se utilizó PCR múltiple para la detección de betalactamasas tipo CTX-M (grupo 1, 2, 9 y 8/25), SHV, TEM y AmpC de origen plasmídico en aislados positivos a BLEE. Un total de 22 de 371 aislados fueron positivos a BLEE por test de doble disco, 11 E. coli (Ec -BLEE) y 11 K. pneumoniae (Kp-BLEE). La PCR detectó CTX-M grupo 1 en los 22 aislados positivos a BLEE. Se observó multirresistencia en todos los aislamientos productores de BLEE. En conclusión, se encontró una alta frecuencia de multirresistencia en Ec-BLEE y Kp-BLEE. La principal BLEE detectada fue CTX-M grupo 1, que también predomina en aislados humanos.

Se realizó una encuesta a los jefes de familia en las viviendas utilizando como instrumento una guía de entrevista validada por expertos. La información recolectada se transfirió a una hoja de Excel® para ser procesada con el software Epidat 4.2. El 70% (IC95% = 65,8-74,2%) de las viviendas tuvo canes. Los centros poblados con mayor tenencia de canes fueron Tunyabamba y Mateclla (100%, respectivamente). La mayoría de viviendas tuvo un solo can (51,3%), con predominio del sexo macho (68,8%) y edades entre 2 y 8 años (77,6%). Pocas familias tuvieron en confinamiento a sus canes (19%) y los han esterilizado (2%). Sin embargo, aunque la mayoría de los canes fueron vacunados contra la rabia (81,9%), son pocos los que tuvieron control veterinario (16%). Todos los centros poblados, a excepción de California, tuvieron en promedio un can por vivienda. En el distrito existen 1.717 canes con propietario y una razón de tres personas por cada can. Los centros poblados de Llactabamba, Acco, Tunyabamba, Lambraspata, Los Ángeles, Sotapa Pararani y otros tuvieron una razón de dos personas por can. En conclusión, existe excesiva cantidad de canes en el distrito de Huancarama, constituyendo una proporción elevada en relación con la de personas.

ABSTRACT The objective of the research was to estimate the population of dogs with an owner and to evaluate some aspects of their sanitary status in the district of Huancarama. The study was quantitative, observational, descriptive and cross-sectional. It was carried out in November 2020. The dwellings were selected through a proportional random stratified sampling considering the populated centers as strata. A survey of household heads was conducted using an interview guide validated by experts as an instrument. The information collected was transferred to an Excel* sheet to be processed later with the Epidat 4.2 software. 70% (95% CI = 65, 8-74, 2%) of the dwellings had dogs. The populated centers with the highest proportion of dog ownership were Tunyabamba and Mateclla (100%, respectively). Most of the dwellings had only one dog (51, 3%), with a predominance of the male sex (68, 8%) and ages between 2-8 years (77, 6%). Few families have their dogs confined (19%) and have them sterilized (2%). However, although the majority of the dogs were vaccinated against rabies (81,9%), few had veterinary control (16%). All populated centers, with the exception of California, had an average of one can per dwelling. In the district there are 1.717 dogs with owners and a ratio of three people to each dog. The population centers of Llactabamba, Acco, Tunyabamba, Lambraspata, Los Angeles, Sotapa Pararani, and others had a ratio of two people per dog. In conclusion, there is an excessive number of dogs in the district of Huancarama, constituting a high proportion in relation to that of people.

Comparación de los valores de glucosa en caninos obtenidos con glucómetros portátiles y la prueba estándar de laboratorio / Comparação dos valores de glicose em caninos obtidos com glicômetros portáteis e o teste laboratorial padrão / Comparison of glucose values in dogs obtained with portable glucometers and the standard laboratory test

La medición de glucosa en caninos es un procedimiento habitual en la clínica diaria, actualmente este valor se puede obtener mediante dispositivos portátiles y pruebas laboratoriales. Se realizó esta investigación con el fin de aportar mayor conocimiento sobre la importancia de la medición de glucosa, ya que en los últimos años ha perdido valor entre las pruebas hematológicas a considerar debido a que solo se relaciona con determinadas patologías como la diabetes u otras enfermedades metabólicas. El presente trabajo tiene como objetivo comparar los valores de glucosa en caninos obtenidos mediante un glucómetro portátil de uso humano (Accu-chek® Active, Roche Diagnostic, Mannheim, Alemania); veterinario (aLcose® Vet Glu, jjPlus Corporation, New Taipei, Taiwán) y la prueba estándar de laboratorio, esto nos indicará la fiabilidad de los resultados obtenidos mediante estos métodos. Se realizó la toma de muestras de sangre de 50 caninos clínicamente sanos, de los cuales se obtuvo el resultado de glucemia mediante estos tres métodos. Los resultados de nuestra investigación evidenciaron que las tres formas de evaluación de la glucosa sanguínea en perros brindaban resultados estadísticamente diferentes (p < 0.05). Se obtuvo valores de glucosa diferentes entre los tres métodos de medición, teniendo como promedios finales 84.14 mg/dL, 101.12 mg/dL y 91.12 mg/dL correspondientes al glucómetro portátil de uso humano, veterinario y a la prueba estándar de laboratorio respectivamente. En conclusión, los glucómetros portátiles de uso humano subestiman los valores reales de glucosa, mientras que los de uso veterinario lo sobreestiman, comparados con la prueba estándar de laboratorio.

A medição de glicose nos cães é um procedimento habitual realizado no atendimento clínico. Atualmente este valor pode ser obtido por meio de dispositivos portáteis e testes laboratoriais. Esta pesquisa foi realizada com a finalidade de destacar a importância da medição de glicose, visto que nos últimos anos esta avaliação não tem sido muito valorada entre os testes hematológicos, sendo considerada relevante apenas em relação a patologias como a diabetes e outras doenças metabólicas. O presente estudo teve como objetivo comparar os valores de glicose em cães obtidos com glicômetro portátil de uso humano; veterinário e o teste padrão de laboratório. Esta comparação poderá indicar a confiabilidade dos resultados obtidos mediante os métodos avaliados. Foi realizada a amostragem do sangue de 50 caninos clinicamente sadios os quais foram submetidos a avaliação de glicose mediante os três métodos. Os resultados de nossa investigação evidenciaram que as três formas de avaliação da glicose sanguínea têm resultados estatisticamente diferentes (p < 0,05). Os valores de glicose tiveram medias finais de 84,14 mg/dL, 101,12 mg/dL e 91,12 mg/dL para o glicômetro portátil de uso humano (Accu-chek® Active, Roche Diagnostic, Mannheim, Alemanha), veterinário (aLcose® Vet Glu, jjPlus Corporation, Nova Taipei, Taiwan) e o teste padrão de laboratório, respectivamente. Ao concluir, os glicômetros portáteis de uso humano subestimam os valores reais de glicose e os de uso veterinário os superestimam quando comparados com o teste padrão de laboratório.

The measurement of glucose in canines is a common procedure in daily clinical practice. Currently this value can be obtained by use of portable devices and laboratory tests. This research was carried out in order to provide more knowledge about the importance of glucose measurement, since in recent years it has lost value among the hematological tests to be considered because it is only related to certain pathologies such as diabetes or other metabolic diseases. The present study aimed to compare the glucose values in dogs obtained with a portable glucometer for human use, veterinarian use, and the standard laboratory test. This comparison may indicate the reliability of the results obtained through the evaluated methods. A blood sampling of 50 clinically healthy canines was taken and submitted to glucose evaluation using the three methods. Our investigation showed that the three ways of assessing blood glucose have statistically different results (p < 0.05). Glucose values had final averages of 84.14 mg/dL, 101.12 mg/dL, and 91.12 mg/dL for the portable glucometer for human use (Accu-chek® Active, Roche Diagnostic, Mannheim, Germany), veterinary (aLcose® Vet Glu, jjPlus Corporation, New Taipei, Taiwan) and the standard laboratory test, respectively. In conclusion, portable glucometers for human use underestimate the glucose values, and those for veterinary use overestimate them compared to the standard laboratory test.

Veterinary Biotypology: a review and new possibilities

The truths surrounding medical practices are seasonally challenged by innovative concepts that can aggregate changing procedures in many degrees. The Galtonian eugenics issues supported the pure-breed idea in dictatorial governments, and introduced mesological studies, turning possible to join genetic concepts to the physiology and psychology of the human organism. Following human medicine, more therapeutic models need to forthcoming in domestic animals. The companionship necessity and the highly responsive behavior have addressed the domestication of dogs and their relationship to owners, to an endpoint that both share the same pathologies. Thus, traditional human concepts of biotypology could be extended to companion animals. Grauvogl (1811-1877) proposeda simple biochemical correlation between physiological states and the miasmas of sick individuals (oxygenoid -syphilis, hydrogenoid -sycosis, carbo-nitrogenoid -psora). Antoine Nebel (1870-1954) correlated biochemical status with the musculoskeletal system and behavior as well. Leon Vannier (1880-1963) model, whose morphophysiological distortions and behavioral inconsistencies were explained by the carbon element and variations in its bonds with phosphorus or fluor radicals was another attempt to categorize and predefine physiology states. Following the advent of structural and functional identification of thyroid hormone in the 1940s, Henri Bernard described the neuro-morphofunctional plasticity of individuals guided by their predominant embryonic leaflet and consequent hormonal diseases. Methods:This work is a narrative review with the purpose of describing and discussingthe legacy ofbiotypology studies and their applicability in dog therapy, and proposinga new homeopathic approach in veterinary medicine based on the miasmas, also contributing to the scarcelyavailable literature. Results:Based on cellular exchanges and consequent metabolic rate, animals can be classified into psoric (no evidence of clinical signs, stable behavior, and adequate exonerative cellular processes); sycotic (cellular dysfunction with alterations in oxidative phosphorylation processes allowing accumulation of cellular toxins such as reactive oxygen and nitrogen species; clinically culminating in chronic inflammations in noble organs, and purulent discharges; unstable and polarized behavior) and syphilitic (whose cellular alterations have reached the molecular level, reducing protein expression and determining cellular toxicity and loss of function; indifferentbehavior). Generalities such as temperature influence, weight, thirst and feedingshall also be considered. Discussion and Conclusion: Thismodel could benefit stray animals, newly adopted or even from shelters, whose actual behavior is unknown, and the search for the Simillimum may be impaired.

High dilution in Leukopenia treatment in five dogs

Leukopenia is associated with the consumption of peripheral leukocytes, decreasedproduction due to endotoxemia and septicemia, medullary hypoplasia, nutritional diseases orautoimmune reactions. In a case report by Narita et al, Echinacea angustifolia demonstrated theeffectiveness of treatment of leukopenia in penguins. Aims:Report the evolution of homeopathictreatment in 5 dogs' patients between 3 and 5 years old, presenting leukopenia. Methodology:The homeopathic treatment was chosen, using Echinaceaangustifolia due to its immunostimulant andimmunomodulatory actions, which evolution was analyzed by blood tests. The exposedinformation is consented by the tutors. Results:The same protocol was made for all of the patients, including 4 globules of Echinacea angustifolia 6 cH orally, every 12 hours for 30 days. The first dog attended on 07/21/2021, presented 4.000 leukocytes, which increased to 6.800 on 08/17/2021. Thesecond patient attend on 12/07/2021 presented 4.700 leukocytes, increasing to 6.800 on 01/25/2022. The third patient attended on 08/24/2021 presented 5.400 leukocytes, which increased to 6.800 on 10/15/2021. The fourth patient presented 4.300 leukocytes on 01/13/2022, increasing to 5.500 on 02/11/2022. The fifth patient presented on12/12/2021 4.600 leukocytes, increasing to 8.400 on 02/03/2022. Therefore, the average of the first collection was 3.681 leukocytes and in the second there was an increase to 6.860 leukocytes (T-test, p= 0,0167). Conclusion:The use of the homeopathic medicine Echinacea angustifolia shows great results, being a viableoption for the treatment of leukopenia, without the side effects.

Mycoplasma maculosum and Mycoplasma spumans associated with fertility disorders in dogs from a Bernese Mountain dog kennel / Mycoplasma maculosum y Mycoplasma spumans asociados con desórdenes defertilidad en perros de un criadero de boyero de Berna

Abstract The aim of this short communication is to describe a case of subfertility and otheranomalies associated with the presence of Mycoplasma spumans and Mycoplasma maculosumin a Bernese Mountain Dog kennel. After the arrival of two dogs from abroad, some fertilitydisorders, such as unsuccessful mating, pregnancy losses and abnormal sperm analysis results,were observed. Two consecutive samplings (vaginal swabs) of three and two bitches with prob-lems, respectively, were performed and M. spumans and M. maculosum were identified by PCRand sequencing. After treatment for 15 days with doxycycline and 9 days with azithromycin,successful pregnancies were achieved and the results of the sperm analyses were reversed.Considering that no other infectious agents causing subfertility problems were detected andthat no management measures or other medication apart from these antibiotics were applied,it was concluded that fertility problems were due to the presence of these two Mycoplasmaspecies.

Retrospective study on the incidence of cats and dogs' spinal injuries by computed tomographic scan. Part I: Cervical and Cervicothoracic / Estudo retrospectivo sobre incidência de injúrias em coluna vertebral de cães e gatos por meio de exame tomográfico. Parte I: Cervical e Cervicotorácica

Injuries involving the spine are frequent in dogs and knowledge of them is important to define the patient's treatment and prognosis. The objective of this retrospective study was to describe the epidemiological profile of animals and lesions in the cervical (C1-5) and cervicothoracic (C6-T2) spine diagnosed through tomographic examination. Compilation of computed tomography (CT) reports for the referred regions was carried out in a diagnostic center between 01/04/2017 and 30/04/2020, with or without contrast, from the clinical routine, in order to relate the most common lesions and their locations, as well as the species, breeds and ages most affected. A total of 1164 CT scans were performed in the period, 57.56% (n=670/1164) for the spine, with 89.7% (n=601/670) reports accessed, where both regions referred to here totaled 26.95% of the studies (n=162/601). Male mixed-breed dogs (MBD) showed the most lesions. For the cervical spine, the most identified lesion was disk extrusion and the site was C3-C4, while the mean age for lesions was 8.09±3.55 years. As for cervicothoracic, disk mineralization was more frequent and the mean age for lesions was 6.96±2.93 years. It was concluded that the spine is the main target of CT scans, that lesions related to the intervertebral disk were the main ones identified, and older MBD animals are the main ones affected.

As lesões envolvendo coluna vertebral são frequentes em animais de companhia, podendo ocorrer à nível vertebral, medula espinal, disco intervertebral, meninges ou raízes nervosas, e o conhecimento das mesmas é importante para definir o tratamento e prognóstico do animal. O objetivo desse estudo retrospectivo foi descrever o perfil epidemiológico dos animais e das lesões em coluna vertebral cervical (C1-5) e cervicotorácica (C6-T2) diagnosticadas por meio de exame tomográfico. Realizou-se a compilação de laudos de tomografias computadorizadas para as referidas regiões realizadas em centro diagnóstico comercial, entre 01/04/2017 a 30/04/2020, contrastadas e não-contrastadas, provenientes da rotina clínica, a fim de relacionar as lesões, raças e locais mais comuns. Foram realizados 1164 exames tomográficos no período avaliado, sendo 57,56% (n=670/1164) para a coluna, com 89,7% dos laudos acessados (n=601/670), sendo que as regiões cervical e cervicotorácica somaram 26,95% dos estudos (n=162/601). Em ambas regiões, os cães sem raça definida (SRD) machos foram os que mais demonstraram lesões. Para a coluna cervical, a lesão mais identificada foi extrusão de disco e o local mais afetado foi C3-C4, enquanto a média de idade para lesões foi 8,09±3,55 anos. Já para cervicotorácica, a mineralização de disco foi mais frequente e média de idade para ocorrência de lesões foi de 6,96±2,93 anos. Concluiu-se que a coluna vertebral foi o principal alvo de tomografias, as lesões relacionadas ao disco intervertebral foram as mais identificadas, sendo animais SRD com idade avançada os mais acometidos.

Retrospective study on the incidence of cats and dogs' spinal injuries by computed tomographic scan. Part II: Thoracolumbar and lumbosacral / Estudo retrospectivo sobre incidência de injúrias em coluna vertebral de cães e gatos por meio de exame tomográfico. Parte II: Toracolombar e Lombossacral

For vertebromedullary injuries, epidemiological knowledge is essential to guide the choice of the most effective diagnostic method. The objective of this retrospective study was to describe the epidemiological profile of animals and thoracolumbar and lumbosacral spine lesions diagnosed by computed tomography scan. A compilation of CT scan reports for the aforementioned regions performed in a comercial diagnostic center from 04/01/2017 to 04/30/2020, contrasted and non-contrasted, from routine, was performed in order to list the most common lesions and their locations, as well as the species, breeds and ages most affected. There were 1164 CT scans performed in the period evaluated, all of them in dogs, 57,56% (n=670) for the spine, with 89,7% reports accessed (n=601), where the regions mentioned here added up to 73,05% studies (n=439). In both regions, male French Bulldog dogs had the most injuries. For the thoracolumbar region, disk mineralization, followed by extrusion, were the most frequent injuries, while the site was T12-13 and the mean age 6,5±3,63 years old. In the lumbosacral, disk protrusion was most frequent, the most affected site was L7-S1 and age 6,65±3,79 years. It was concluded that the spine is the main target of CT scans, and that lesions related to the intervertebral disk were the main ones identified, with chondrodystrophic animals being more predisposed to injury.

Para lesões vertebromedulares é indispensável o conhecimento epidemiológico para direcionar a escolha do método diagnóstico mais eficaz.

Realizou-se a compilação de laudos de tomografias computadorizadas para as referidas regiões realizadas em centro diagnóstico comercial, entre 01/04/2017 a 30/04/2020, contrastadas e não-contrastadas, provenientes da rotina, a fim de relacionar as lesões e seus locais de ocorrência, bem como a espécie, raças e idades mais comuns. Foram realizados 1164 exames tomográficos no período avaliado, sendo 57,56% (n=670) para a coluna, com 89,7% laudos acessados (n=601), nos quais as regiões toracolombar e lombossacral somaram 73,05% dos estudos (n=439). Em ambas as regiões, os cães Bulldog Francês machos foram os que mais apresentaram lesões. Para a região toracolombar, a mineralização de disco, seguida pela extrusão, foram as lesões mais frequentes, enquanto o local foi T12-13 e a média de idade 6,5±3,63 anos. Na lombossacral, a protusão de disco foi mais frequente, o local mais afetado foi L7-S1 e idade de 6,65±3,79 anos. Concluiu-se que a coluna vertebral é o principal alvo de tomografias, e que as lesões relacionadas ao disco intervertebral foram as principais identificadas, sendo os animais condrodistróficos mais predispostos a lesões.

Clostridioides difficile: achados epidemiológicos em animais domésticos em um Hospital Veterinário Universitário em ­ Teresina, PI / Clostridioides difficile: epidemiological findings in domestic animals in a University Veterinary Hospital in Teresina, PI

O objetivo deste estudo foi analisar a prevalência de Clostridioides difficile e suas toxinas (A/B) nas fezes de animais domésticos de um Hospital Veterinário Universitário de Teresina - PI. A detecção de C. difficile e suas toxinas foi realizada por meio de um ensaio imunoenzimático, denominado C. Diff Quik Chek Complete® (TECHLAB), capaz de detectar antígeno Glutamato Desidrogenase (GDH) e as toxinas A/B produzidas pelo bacilo, realizado em amostras fecais de cães (C. lupus) e e gatos (Felis catus) coletadas entre agosto de 2019 a setembro de 2020. Um total de 54 amostras fecais foram analisadas, das quais 16 foram positivas para C. difficile (29,63%). 68,75% (11/16) pertenciam a caninos, enquanto 31,25% (5/16) a felinos. Amostras diarreicas e não diarreicas foram utilizadas para o estudo e uma maior prevalência do bacilo pôde ser identificada em amostras diarreicas (33%). Nenhuma das amostras apresentou toxinas do patógeno. Os achados deste estudo evidenciam que C.difficile está presente no estado do Piauí. Foi possível identificá-lo em todas as espécies e em amostras diarreicas ou não, demonstrando que essa infecção pode se manifestar de formasintomática e assintomática, levantando a possibilidade de infecção cruzada entre o animal e seu tutor.

The aim of this study was to analyze the prevalence of Clostridioides difficile and its toxins (A/B) in the feces of domestic animals at a University Veterinary Hospital in Teresina - PI. The detection of C. difficile and its toxins was performed by an immunogenic enzyme, called C. Diff Quik Chek Complete® (TECHLAB), capable of detecting antigen glutamate dehydrogenase (GDH) and A/B toxins produced by this bacillus, performed in fecal samples of dogs (C. lupus) and cats (Felis catus) collected between August 2019 and September 2020.:54 stools were analyzed, of which 16 were positive for C. difficile (29.63%). 68.75% (11/16) belonged to canines, while 3.25% (5/16) to felines. Diarrheal and non-diarrheal diseases are used for the study and a higher prevalence of bacillus can be identified in diarrheal diseases (33%). None of the samples present pathogen toxins. The results of this study show that C. difficile is present in the state of Piauí. It can be identified in all species and in diarrheal or non-diarrheic samples, demonstrating that this infection can be symptomatic and asymptomatic, giving the possibility of cross-infection between the animal and its owner.

Ocorrência de Babesia sp, Ehrlichia canis e Hepatozoon canis em cães domiciliados, em dois municípios do estado do Espírito Santo - Brasil / Occurrence of Babesia sp, Ehrlichia canis and Hepatozoon canis in domiciled dogs in two municipalities of the state of Espírito Santo - Brazil / Ocurrencia de Babesia sp, Ehrlichia canis y Hepatozoon canis em perros domiciliados em dos municipios del estado de Espírito Santo - Brasil

As doenças transmitidas por carrapatos são afecções de grande importância na clínica médica de pequenos animais, devido à alta casuística e ampla distribuição vetorial no território brasileiro. Os principais agentes responsáveis pelas infecções em cães são Babesia sp., Ehrlichia canis e Hepatozoon canis. Os animais infectados são assintomáticos ou apresentam sinais clínicos inespecíficos, sendo necessário a utilização de testes diagnósticos para definição do agente etiológico, e diagnóstico seguro. O objetivo do presente estudo foi determinar a ocorrência desses micro-organismos em cães naturalmente infectados, domiciliados nos municípios de Vila Velha e Anchieta, Espírito Santo, utilizando diferentes testes de detecção: Reação em cadeia polimerase (PCR), sorologia para detecção de anticorpos anti Ehrlichia canis e pesquisa de hematozoários em esfregaço sanguíneo. Foram analisadas 65 amostras de sangue obtidas por venopunção de veia cefálica de cães. No teste de PCR, 4,62% dos animais foram positivos para Babesia vogeli e 1,54% para Ehrlichia canis sendo os resultados para Hepatozoon canis negativos. No teste sorológico para E. canis 90,77% dos animais foram positivos para a presença de anticorpos, e na pesquisa em lâminas de esfregaço sanguíneo 3,02% apresentavam outros hemoparasitas. Os resultados indicam a dispersão desses hemoparasitas na população canina da região de estudo, entretanto com baixa ocorrência. O teste de PCR demonstrou-se como o mais sensível no qual Babesia vogeli foi o agente mais observado.(AU)

Tick-borne diseases are diseases of great importance in the medical practice of small animals, due to the high casuistry and wide vectorial distribution in the Brazilian territory. The main agents responsible for infections in dogs are Babesia sp., Ehrlichia canis and Hepatozoon canis. Infected animals are asymptomatic or present nonspecific clinical signs, requiring the use of diagnostic tests to define the etiologic agent, and safe diagnosis. The objective of the present study was to determine the occurrence of these microorganisms in naturally infected dogs domiciled in the municipalities of Vila Velha and Anchieta, Espírito Santo, using different detection tests: polymerase chain reaction (PCR), serology to detect antibodies against Ehrlichia canis and research of hematozoa in blood smears. Sixty-five blood samples obtained by venipuncture of the cephalic vein of dogs were analyzed. In the PCR test, 4.62% of the animals were positive for Babesia vogeli and 1.54% for Ehrlichia canis, and the results for Hepatozoon canis were negative. In the serological test for E. canis, 90.77% of the animals were positive for the presence of antibodies, and in the research in blood smear slides, 3.02% presented other hemoparasites. The results indicate the dispersion of these hemoparasites in the canine population of the study region, however with low occurrence. The PCR test proved to be the most sensitive, in which Babesia vogeli was the most observed agent.(AU)
