Eighty-five years awaiting for description: a new species of Tabanus Linnaeus (Diptera: Tabanidae) from the Paraná State, in Brazil

ABSTRACT The largest genus within the family Tabanidae (Diptera: Brachycera), Tabanus Linnaeus, has a worldwide distribution and includes medium to large conspicuous flies. Although the species are difficult to identify and a large number have already been described, several new Neotropical species have been reported for science in the past few years. Taxonomy, the science that describes and catalogs biodiversity, depends on collections, as these preserve specimens for later purposes, allowing examination and checking by specialists. In this paper we describe a new species, Tabanus argentistrigatus sp. n. based on two specimens stored in the collection of the Museum of Zoology of the São Paulo University since 1938. The new species is only known from one location in the state of Paraná, which is now highly anthropized.

Tabanidae (Diptera) collected on horses in a Cerrado biome in the state of Tocantins, Brazil / Tabanidae (Diptera) coletadas em equinos no bioma Cerrado no estado do Tocantins, Brasil

Abstract Tabanidae (Diptera), popularly known as horse flies, is an important vector group. This is the first study to ascertain the abundance and diversity of horse flies in horses at the cerrado biome of the state of Tocantins, Brazil. Collecting took place in typical Cerrado, and sampling occurred in the dry and rainy seasons. The horseflies were collected from horses using an entomological net. A total of 249 individuals were collected and spread over 25 species. The prevalent species were Stypommisa aripuana (25.8%) and Catachlorops rufescens (6.4%), in the dry period, and Fidena lissorhina (22.5%), Tabanus occidentalis var. dorsovittatus (10%) and Poeciloderas quadripunctatus (6.4%), in the rainy season. The results suggest that tabanids attack horses throughout the dry and rainy seasons, posing a constant threat to their health in the Cerrado of Tocantins.

Discrimination of cryptic species: Tabanus triangulum and Tabanus occidentalis (Diptera: Tabanidae) differ in size and shape / Distinção de espécies crípticas: Tabanus triangulum e Tabanus occidentalis (Diptera: Tabanidae) diferem em tamanho e forma

Abstract Horse fly females (Diptera, Tabanidae) are hematophagous and can vector pathogens that affect livestock. Complexes of cryptic species are common in Tabanidae, as exemplified by some species of Tabanus, including Tabanus triangulum and Tabanus occidentalis, both prevalent in the Southern region of Brazil. In this study, geometric morphometrics were employed to ascertain the wing venation in species identification. It was demonstrated that this tool effectively differentiates T. triangulum from T. occidentalis in the coastal plain of Rio Grande do Sul state, situated within the Pampa biome. The results indicate that T. triangulum and T. occidentalis occupy distinct regions of the morphological space, allowing their precise identification through geometric morphometrics, which is fast, affordable, and easy to implement.

Resumo Fêmeas de mutucas (Diptera, Tabanidae) são hematófagas e podem ser vetores de patógenos que afetam animais de criação. Complexos de espécies crípticas são comuns em Tabanidae, como exemplificado por algumas espécies de Tabanus, incluindo Tabanus triangulum e Tabanus occidentalis, ambas prevalentes na região Sul do Brasil. Neste estudo foi utilizada morfometria geométrica para avaliar a venação das asas na identificação de espécies. Foi demonstrada que essa ferramenta diferencia, efetivamente, T. triangulum de T. occidentalis na Planície Costeira do Rio Grande do Sul, situada no bioma Pampa. Os resultados indicam que T. triangulum e T. occidentalis ocupam regiões distintas do espaço morfológico, permitindo sua identificação precisa por meio da morfometria geométrica, a qual é rápida, acessível e fácil de implementar.

Development, Histological, and Ultrastructural Evaluation of Sheep Hyperimmune Serum Therapy for COVID-19 / Desarrollo, Evaluación Histológica y Ultraestructural de la Terapia con Suero Hiperinmune de Oveja para COVID-19

SUMMARY: In response to the threat posed by new variants of SARS-CoV-2 and the urgent need for effective treatments in the absence of vaccines, the aim of this study was to develop a rapid and cost-effective hyperimmune serum (HS) derived from sheep and assess its efficacy. The utilization of a halal-certified, easily maintained in certain geographic regions, easy-to-handle animal such as sheep could provide a viable alternative to the expensive option of horses. Sheep were immunized with a whole inactivated SARS-CoV- 2 antigen to produce HS, which was evaluated for neutralizing potency using the PRNT50 assay. K18-hACE2 transgenic mice (n=35) were divided into three groups: control, SARS-CoV-2 exposure through inhalation, and SARS-CoV-2 exposed mice treated with HS. HS efficacy was assessed through serum proinflammatory cytokine levels, qRT-PCR analysis, histopathological examination of lungs and hearts, and transmission electron microscopy. Purified HS exhibited significant neutralizing activity (1/24,576). The SARS-CoV-2+HS group showed lower levels of TNF-α, IL-10, and IL-6 (P<0.01) and relatively lower levels of MCP-1 compared to the SARS-CoV-2 group. HS prevented death, reduced viral RNA levels in the lungs and hearts, protected against severe interstitial pneumonia, preserved lung tissue integrity, and prevented myocyte damage, while the SARS-CoV-2 group exhibited viral presence in the lungs. This study successfully developed a sheep-derived HS against the entire SARS-CoV-2 virus, resulting in a significant reduction in infection severity, inflammation, and systemic cytokine production. The findings hold promise for treating severe COVID-19 cases, including emerging viral variants, and immunocompromised patients.

En respuesta a la amenaza que suponen las nuevas variantes del SARS-CoV-2 y la urgente necesidad de tratamientos eficaces en ausencia de vacunas, el objetivo de este estudio fue desarrollar un suero hiperinmune (HS) rápido y rentable derivado de ovejas. y evaluar su eficacia. La utilización de un animal con certificación halal, de fácil mantenimiento en determinadas regiones geográficas y de fácil manejo, como las ovejas, podría proporcionar una alternativa viable a la costosa opción de los caballos. Las ovejas fueron inmunizadas con un antígeno de SARS-CoV-2 completamente inactivado para producir HS, cuya potencia neutralizante se evaluó mediante el ensayo PRNT50. Los ratones transgénicos K18-hACE2 (n = 35) se dividieron en tres grupos: control, exposición al SARS-CoV-2 mediante inhalación y ratones expuestos al SARS-CoV-2 tratados con HS. La eficacia de HS se evaluó mediante niveles de citoquinas proinflamatorias en suero, análisis qRT-PCR, examen histopatológico de pulmones y corazones y microscopía electrónica de transmisión. El HS purificado exhibió una actividad neutralizante significativa (1/24,576). El grupo SARS-CoV-2+HS mostró niveles más bajos de TNF-α, IL-10 e IL-6 (P<0,01) y niveles relativamente más bajos de MCP-1 en comparación con el grupo SARS-CoV-2. HS evitó la muerte, redujo los niveles de ARN viral en los pulmones y el corazón, protegió contra la neumonía intersticial grave, preservó la integridad del tejido pulmonar y evitó el daño de los miocitos, mientras que el grupo SARS-CoV-2 exhibió presencia viral en los pulmones. Este estudio desarrolló con éxito un HS derivado de ovejas contra todo el virus SARS-CoV-2, lo que resultó en una reducción significativa de la gravedad de la infección, la inflamación y la producción sistémica de citocinas. Los hallazgos son prometedores para el tratamiento de casos graves de COVID- 19, incluidas las variantes virales emergentes y los pacientes inmunocomprometidos.

Performance of Horse Gram [Macrotyloma uniflorum (L.) Verdc] Germplasm for Seed Yield and Its Component Characters

The present investigation was carried out with 78 diverse horse gram [Macrotyloma uniflorum (L.) Verdc] genotypes along with 4 checks during the late Kharif season. Data was recorded on days to 50 percent flowering, days to maturity, plant height, number of branches per plant, pod length, number of seeds per pod, number of pods per plant, pod weight (g), seed yield per plant (g), and 100-seed weight (g). Analysis of variance revealed significant differences among all the genotypes for all the characters studied. A wide range of variations had been observed for all the characters except for the number of seeds per pod. The highest coefficient of variation was observed in the number of pods per plant followed by 100 seed weight and seed yield per plant. The phenotypic coefficients of variation (PCV) were higher than the genotypic coefficient of variation (GCV) for all the traits but the differences were narrow. The highest magnitude of PCV and GCV were recorded for seed yield per plant (g) followed by pod weight (g) indicating a wide range of variation which provides a chance for yield improvement. High heritability coupled with high genetic advance was observed for plant height, number of branches per plant, number of pods per plant, pod weight, seed yield per plant, and 100 seed weight indicating additive gene action and the abundant scope for improvement in these traits through simple selection. This study provides information about the performance of the genotypes and identifies some prominent genotypes. Thirty-three genotypes recorded significantly higher seed yield per plant as compared to the best-performing check. These genotypes were IC 426292, IC 470167, IC 426471, IC 470229, IC 470206, IC 470262, IC 426464, IC 107247, IC 108076, IC 426550, IC 426540, IC 108078, IC 426537, IC 470166, IC 467865, CRHG-1, IC 426539, IC 426478, IC 426524, IC 426549, IC 426522, IC 470170, IC 261278, IC 470188, IC 426535, IC 107222, IC 226533, IC 426574, IC 426523, IC 526965, IC 426571, IC 426517 and IC 426538. These genotypes may be further used for parental selection in breeding programs for the improvement of yield and its attributes in horse gram.

Assessment of Genetic Correlation, Path Coefficient Analysis and Principal Component Analysis in Horse Gram under Water Stress

A field experiment was conducted to evaluate the correlation and path analysis in thirty horse gram germplasm lines under moisture-stressed conditions using various selected characters. The association studies revealed a significant positive correlation of seed yield with relative water content, number of pods per plant, number of seeds per pod, total chlorophyll content, harvest index, proline content, root dry weight, root length and leaf area index. While days to 50% flowering, days to maturity, plant height and number of primary branches showed a significant negative correlation with yield. Path coefficient analysis revealed a high positive direct effect of the number of pods per plant on seed yield and the number of seeds per pod recorded exhibited the highest indirect effect on seed yield via the number of pods per plant under moisture stress conditions in horse gram. So, selection based on the number of pods per plant will be more beneficial under water stress conditions. The exploitation of genetic diversity is key to a successful breeding program. The principal component analysis using selected fifteen characters revealed the existence of adequate genetic variability among genotypes under study. First four principal components accounted for a cumulative variance of 82.47%. The principal component analysis (PCA) biplot revealed genotypes viz. IC22785, IC392329, HG 26L and IC20753 to highly diverse and these genotypes may be employed for enhancement of various traits in horse gram.

Objective:To observe the effect of horse-riding squat exercise plus Governor Vessel-regulating Tuina(Chinese therapeutic massage)therapy on static balance function in patients with stroke.Methods:A total of 176 stroke patients were enrolled as the study subjects and divided into four groups by the random number table method,namely horse-riding squat+Tuina group,horse-riding squat group,Tuina group,and control group,with 44 cases in each group.The control group was treated with rehabilitation balance training.The horse-riding squat+Tuina group,horse-riding squat group,and Tuina group were treated with additional horse-riding squat exercise plus Tuina,horse-riding squat exercise,and Tuina treatment,respectively.Four weeks of treatment was regarded as one treatment course.After 1 treatment course,the balance function of the four groups was compared.Results:After treatment,the ellipse area of motion and the length of motion in all four groups were reduced,and the intra-group differences were all statistically significant(P＜0.05).The difference in the ellipse area of motion before and after treatment in the horse-riding squat+Tuina group and the horse-riding squat group was larger than that in the control group,and the differences were statistically significant(P＜0.05).The difference in the ellipse area of motion before and after treatment in the horse-riding squat+Tuina group was larger than that in the Tuina group,and the difference was statistically significant(P＜0.05).The difference in the length of motion before and after treatment in the horse-riding squat+Tuina group,the horse-riding squat group,and the Tuina group was greater than that in the control group,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the pairwise comparison between the horse-riding squat+Tuina group,the horse-riding squat group,and the Tuina group(P＞0.05).Conclusion:Horse-riding squat exercise plus Governor Vessel-regulating Tuina therapy can effectively improve the static balance function in patients with stroke.Training the affected lower limb weight-bearing exercise,adjusting the center of gravity distribution,and promoting the mutual balance and coordination between muscle groups may be the mechanism of improving the static balance function.

First report of Leishmania (Mundinia) martiniquensis in South American territory and confirmation of Leishbunyavirus infecting this parasite in a mare

BACKGROUND Epidemiological data related to leishmaniases or Leishmania infection in horses are scarce. However, studies carried out in different regions in the world showed equids parasitised by Leishmania braziliensis, L. infantum and L. martiniquensis. OBJECTIVES Identify the Leishmania species causing cutaneous leishmaniasis in a mare, living in Rio de Janeiro State (Brazil), and search the presence of Leishmania viruses in the isolated parasite. METHODS Isoenzymes and polymerase chain reaction (PCR) targeting ITSrDNA region followed by sequencing were conducted for typing the isolated parasite. A search for Leishmania virus infection was also performed. FINDINGS The mare presented skin nodules and ulcers in the left pinna caused by Leishmania spp. that was detected by culture and PCR. The parasite was identified as Leishmania (Mundinia) martiniquensis, infected by Leishbunyavirus (LBV), representing the first description of this species in South America. The animal travelled to different Brazilian regions, but not to outside the country. MAIN CONCLUSIONS The worldwide distribution of L. martiniquensis and its infection by LBV were confirmed in this study, indicating the autochthonous transmission cycle in Brazil. The clinical profile of the disease in the mare, showing fast spontaneous healing of cutaneous lesions, may indicate that skin lesions related to L. martiniquensis infection in horses might be underdiagnosed.

Presence of Helicobacter spp. in dental tartar and gastric mucosa, and its relationship with EGUS in horses from a public slaughterhouse

Background: Despite the fact that Helicobacter spp. has been detected in equine gastric mucosa, no evidence exists about this infection in Colombian horses affected by equine ulcerative gastric syndrome (EGUS), nor in dental tartar. Objective: To detect Helicobacter spp. DNA in equine gastric mucosa and dental tartar and determine the relationship between the presence of Helicobacter spp. and gastric lesions. Methods: Samples of glandular gastric mucosa and dental tartar were collected from 30 equine slaughterhouses. Macroscopic lesions of the stomachs were classified and the total DNA in all samples was extracted using a commercial extraction kit. A final-point PCR was performed using primers for amplification of a segment of 251 bp of the gene encoding the 16s rRNA region; the amplified fragments were subjected to a second PCR to determine the presence of H. pylori, the VacA gene was typified. The resulting amplicons were sequenced. Results: It was possible to amplify 16s rRNA in several samples but there was no amplification of VacA. Fragments of the sequences were compatible with H. heilmannii. The 23.3 and 10% of gastric and tartar samples were positive for 16s rRNA of Helicobacter spp., respectively. Conclusion: Although genetic material of Helicobacter spp. was found in some animals, there was no relationship with gastric lesions. It is possible that helicobacteriosis has no bearing in EGUS etiology.

Antecedentes: A pesar de que se ha detectado Helicobacter spp. en mucosa gástrica equina, no existe evidencia de esta infección en caballos criollos colombianos afectados por síndrome ulcerativo gástrico (SUGE), ni tampoco reportes en sarro dental. Objetivo: Detectar ADN de Helicobacter spp. en sarro dental y mucosa gástrica de equinos, y determinar la relación entre la presencia de la bacteria y lesiones gástricas. Métodos: Las muestras de mucosa glandular gástrica y sarro dental fueron colectadas de 30 equinos que se encontraban en planta de beneficio. Las lesiones macroscópicas fueron clasificadas y el ADN total de las muestras fue extraído utilizando un kit comercial. Se desarrolló PCR convencional usando cebadores específicos para la amplificación de un segmento de 251 pb de un gen que codifica la región 16S del ARNr; los fragmentos amplificados fueron sometidos a una segunda PCR para determinar la presencia de H. pylori mediante la amplificación del gen VacA. Los amplificados resultantes fueron secuenciados. Resultados: Fue posible amplificar 16s ARNr en varias muestras, pero no hubo amplificación de VacA. Los fragmentos de las secuencias fueron compatibles con H. heilmannii. El 23,3 y 10% de las muestras gástricas y sarro fueron positivas para 16s ARNr de Helicobacter spp., respectivamente. Conclusión: Aunque el material genético de Helicobacter spp. se encontró en algunos animales, no hubo relación con las lesiones gástricas. Es posible que la helicobacteriosis no tenga incidencia en la etiología del EGUS.

Avaliação de soluções eletrolíticas e vias da administração sobre o teor de umidade das fezes de equinos desidratados experimentalmente / Evaluation of electrolyte solutions and administration routes on the moisture content of feces of experimentally dehydrated horses

A ocorrência de processos fisiopatológicos que cursam com desidratação da ingesta no trato gastrointestinal dos equinos é comum na rotina clínica. Fatores como diminuição da motilidade intestinal e sobrecarga intraluminal de conteúdo desidratado podem levar a compactação em segmentos como estômago, ceco e cólons. Este estudo objetivou realizar a comparação entre soluções eletrolíticas enterais hipotônica (SeHIPO) e isotônica (SeISO) e a solução Ringer com lactato de sódio (RL IV) sobre o teor de umidade das fezes de equinos submetidos a um período de desidratação experimental (PD). Foram utilizados seis equinos adultos, todas fêmeas com idades entre 10 e 15 anos, média de 440 kg de peso corpóreo. O PD constou de 36 horas de jejum hídrico e alimentar associadas a duas administrações intravenosas de furosemida, sendo a primeira imediatamente no início (T-36) e a segunda 12 horas após o início do PD. Os tratamentos utilizados foram: SeHIPO e SeISO, ambas administradas por via nasogástrica em fluxo contínuo (HETfc), e RL IV administrada pela via intravenosa. Todos os tratamentos foram administrados a uma taxa de infusão contínua de 15mL kg-1 h-1 durante 8 horas consecutivas. O delineamento experimental utilizado foi o crossover6x3, onde cada animal foi submetido, em sistema de rodízio, aos três tratamentos em momentos distintos. As soluções eletrolíticas enterais demonstraram maior eficácia na recomposição do teor de umidade das fezes quando comparadas à terapia RL IV. A hidratação enteral com soluções isotônicas e hipotônicas administrada em fluxo contínuo são eficazes em restaurar o teor de umidade das fezes, podendo ofertar uma opção econômica, segura e eficiente na reidratação de pacientes e nas afecções que cursam como obstruções intraluminais simples.

The occurrence of pathophysiological processes that curse with digesta dryness in the gastrointestinal tract of horses is common in clinical routine, factors such as decreased intestinal motility and intraluminal overload of dry content can lead to compaction in segments such as cecum and colon. This study aimed to compare a hypotonic enteral solution (SeHIPO), an isotonic enteral solution (SeISO) and a Ringer with sodium lactate solution (RL IV) over the moisture content of equine feces submitted to an experimental dehydration protocol. Six adult horses were used, all females aged between 10 and 15 years, average body weight of 440 kg. The PD consisted of a 36 hours period of water and food fasting associated with two intravenous administrations of furosemide, the first immediately at the beginning (T-36) and the second 12 hours after the beginning of the PD. The treatments used were: SeHIPO (hypotonic enteral solution administered via nasogastric), SeISO (enteral isotonic solution administered via nasogastric) and RL IV (Ringer's solution with sodium lactate administered intravenously), all treatments were administered by continuous infusion at a rate of 15mL kg-1 h-1 for 8 consecutive hours. The experimental design used was the 6x3 crossover, where each animal is submitted, in a rotation system, to the three treatments at different times. Enteral fluid therapy with isotonic and hypotonic solutions administered in continuous flow are effective in restoring the moisture content of feces, and may offer an economical, safe, and efficient option for rehydrating patients and in conditions that progress as simple intraluminal obstructions.

Protocol-optimizing study of combining Tuina and horse-riding squat exercise for knee osteoarthritis / 针灸推拿医学（英文版）

Objective: To evaluate the efficacy of Tuina (Chinese therapeutic massage) manipulation plus horse-riding squat exercise in treating knee osteoarthritis (KOA) and optimize the combining protocol. Methods: Based on a 2×2 factorial design, 120 eligible KOA patients were randomized into a manipulation group (group A1B2), a manipulation plus horse-riding squat group (group A1B1), a sitting knee-adjustment group (group A2B2 group), and a sitting knee-adjustment plus horse-riding squat group (group A2B1), with 30 cases in each group. The intervention was conducted three times a week, lasting for four weeks. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) was taken as the major measure for efficacy evaluation (including three component scores, pain, stiffness, and daily function, and total score). Results: The three component scores (pain, stiffness, and daily function) and the total score of WOMAC showed significant differences after the intervention in the four groups (P<0.05). There were significant inter-group differences in the WOMAC stiffness score amongst the four groups after the intervention (P<0.05). In group A1B1, the step length, stride, walking speed, and knee joint flexion angle changed significantly after treatment (P<0.05). After the intervention, the step length changed significantly in group A1B2 (P<0.05), and the walking speed changed significantly in group A2B1 (P<0.05). There were no significant differences in the step length, stride, walking speed, or knee joint flexion angle among the four groups (P>0.05). The extensor peak torque at 180 °/s changed significantly in group A1B2 after treatment (P<0.05). Neither the intra-group nor the inter-group comparisons of the four groups revealed significant differences in the other isokinetic muscle strength parameters (P>0.05). The main effect of manipulation showed significant in affecting the WOMAC pain and total scores (P<0.05). The main effect of horse-riding squat exercise showed significant in affecting the WOMAC pain and stiffness scores (P<0.05). Conclusion: The four treatment protocols all can improve the symptoms of KOA, for instance, relieving pain and stiffness, and enhancing daily function. Group A2B1 produces the most eminent effect in relieving joint stiffness. The main effects of both manipulation and horse-riding squat exercise are significant in reducing pain. Besides, the main effect of horse-riding squat exercise is significant in relieving joint stiffness.

New records of Tabanidae (Diptera) in an ecotone zone between the Cerrado and the Amazon Forest and an updated list of species of Tocantins, Brazil / Novos registros de Tabanidae (Diptera) em uma zona ecotonal entre o Cerrado e a Floresta Amazônica e lista atualizada de espécies do Tocantins, Brasil

Abstract Tabanidae is a family of the order Diptera composed of insects popularly known as horse flies. Compared to the current knowledge about other insects, tabanids can be considered a well-studied group in Brazil, however, little is known about the Tabanidae fauna in the Tocantins state, since only 44 species had been recorded for the state, which is not a very significant number among the 488 species recorded for the country. Thereby, we aimed to enlarge the knowledge of tabanids present in the state by identifying the specimens collected over the last decade in an important transition area between the Cerrado and Amazon domains. We accounted 302 specimens distributed in three subfamilies (Pangoniinae, Chrysopsinae, and Tabaninae), four tribes (Scionini, Chrysopsini, Diachlorini, and Tabanini), 12 genera, 29 species, and two varieties. Of these, only eight species and the two varieties had been recorded in the Tocantins state, numbering 21 new records for the state. Thus, we updated the records of Tabanidae for the Tocantins state for 65 known species.

Resumo Tabanidae é uma família da ordem Diptera composta por insetos popularmente conhecidos como mutucas. Quando comparado ao conhecimento sobre os demais insetos, os tabanídeos podem ser considerados um grupo bem estudado no Brasil, entretanto pouco se conhece sobre a fauna de Tabanidae do Tocantins, sendo que até então, apenas 44 espécies haviam sido registradas para o estado, um número pouco significativo, já que são registradas 488 espécies para o País. Desse modo, o presente trabalho visou ampliar o conhecimento acerca dos tabanídeos do estado através da identificação dos espécimes coletados ao longo da última década em uma importante área de transição entre os domínios Cerrado e Amazônia. Foram estudados 302 espécimes, distribuídos em três subfamílias (Pangoniinae, Chrysopsinae e Tabaninae), quatro tribos (Scionini, Chrysopsini, Diachlorini e Tabanini), 12 gêneros, 29 espécies e duas variedades. Apenas oito espécies e as duas variedades haviam sido previamente registradas para o Tocantins, totalizando 21 novos registros para o estado. Com isso, os registros de Tabanidae para o Tocantins são atualizados para 65 espécies.

Causes of abortion, stillbirth, and perinatal mortality in horses / Causas de aborto, natimortalidade e morte perinatal em equinos

Causes of abortion, stillbirth, and perinatal mortality in horses were investigated in the Department of Veterinary Pathology of the Federal University of Rio Grande do Sul (SPV-UFRGS) from 2000 to 2015. In this period, 107 cases were analyzed using macroscopic, microscopic, and complementary tests. Of these, 77 were aborted fetuses, 16 were stillbirths, and 14 were perinatal deaths. Conclusive diagnosis was established in 42.8% of the fetuses analyzed, with 28.6% classified as infectious origin, 9.1% as non-infectious, and 5.1% as other. Bacterial infections, especially those related to Streptococcus spp. were the most frequently observed. In stillborn foals, diagnosis was established in 62.5% of cases, and 50% of these were related to non-infectious causes, such as dystocia and birth traumas. As for perinatal mortality, a conclusive diagnosis was reached in 78.57% of cases, and infectious causes associated with bacterial infections accounted for 64.1% of these diagnoses.(AU)

Ectoparasites infesting animals living in close contact with human beings: a real trouble for One Health perspective? / [Ectoparasitos infestando animais que vivem em contato próximo com seres humanos: um problema real para a perspectiva Saúde Única?]

The number of domestic animals living with human beings is rapidly increasing in parallel with an enhanced risk of transmission of their parasites and the pathogens they might carry. The aim of this study was to assess the occurrence of hematophagous arthropods infesting domestic animals from Northeastern Brazil and to remark the implications of their occurrence on the epidemiology and control of selected veterinary and human diseases. From January 2017 to April 2019, ectoparasites infesting domestic cats, dogs and horses were collected for their respective hosts and identified. Overall, ectoparasites were sampled from 86 domestic animals, living in different anthropic settings. A total of 401 specimens (344 ticks and 57 fleas) were collected from different hosts [i.e., 10 (2.49%), 96 (23.94%) and 295 (73.57%) from cats, dogs and horses, respectively]. Two flea (i.e., Ctenocephalides canis and Ctenocephalides felis) and 5 tick species (i.e., Amblyomma ovale, Amblyomma sculptum, Dermacentor nitens, Rhipicephalus microplus and Rhipicephalus sanguineus sensu lato) were identified. This study provides data on the ectoparasite fauna infesting domestic animals from Northeastern Brazil. The diagnosis and treatment of these parasites should not be underestimated, considering the role that hematophagous arthropods display as vectors of pathogens of medical and veterinary concern.(AU)

O número de animais domésticos infestados por ectoparasitos vivendo em estreito contato com seres humanos está aumentando, elevando o risco de infecção pelos patógenos transmitidos por vetores. Objetivou-se neste estudo avaliar a ocorrência de ectoparasitos infestando animais do nordeste do Brasil e discutir as implicações desse parasitismo na epidemiologia e no controle de doenças de importância médico-veterinária. De janeiro de 2017 a abril de 2019, artrópodes foram coletados de gatos, cães e cavalos, e identificados morfologicamente. Ectoparasitos foram removidos de 86 animais infestados provenientes de áreas urbanas e rurais. Foram identificados 401 espécimes (344 carrapatos e 57 pulgas) coletados de diferentes hospedeiros (10 (2,49%), 96 (23,94%) e 295 (73,57%) de gatos, cães e cavalos, respectivamente. Duas espécies de pulgas (Ctenocephalides canis e Ctenocephalides felis) e cinco espécies de carrapatos (Amblyomma ovale, Amblyomma sculptum, Dermacentornitens, Rhipicephalus microplus e Rhipicephalus sanguineus sensu lato) foram identificadas. Este estudo fornece informações sobre a ectofauna de animais domésticos do nordeste do Brasil. Portanto, o diagnóstico e o tratamento desses parasitos não devem ser subestimados, considerando que os artrópodes aqui relatados podem veicular patógenos de importância médico-veterinária.(AU)

Objetivou-se com este estudo demonstrar a influência do tipo de treinamento sobre as medidas dos tendões flexores palmares em equinos de vaquejada que correm à direita do boi na microrregião do Alto Médio Gurgueia, Sul do Piauí, Brasil. Foram utilizados oito animais, da raça quarto de milha e seus mestiços, de diferentes idades, peso e sexo, selecionados e questionados sobre o tempo que exerciam a atividade de vaquejada e o tipo de treinamento a qual eram submetidos, que refere-se a maneira como praticavam a prova correndo de que lado do boi, em uma prova de vaquejada no município de Cristino Castro, Sul do Piauí, Brasil, onde os participantes eram provenientes de diferentes haras da Microrregião do Alto Médio Gurgueia, Sul do Piauí, Brasil. Em cada animal foi realizada ultrassonografia das zonas IB, IIB e IIIB dos tendões flexores digital superficial (TFDS) e digital profundo (TFDP), obtendo-se as medidas dos diâmetros médio lateral (DML) e dorso palmar (DDP) através do plano transverso em cada uma das diferentes zonas. Os dados foram submetidos a análise estatística (ANOVA), utilizando-se o teste t a nível de significância de (p<0,05), observando-se que não houve diferença significativa entre as medidas avaliadas. De acordo com os resultados obtidos, cavalos atletas que correm a direita do boi não apresentam diferença significativa nos diâmetros médio lateral e dorso palmar dos tendões flexores entre os antímeros direito e esquerdo do membro torácico.

The objective of this study was to demonstrate the influence of the type of training on the measurements of the palmar flexor tendons in vaquejada horses that run to the right of the ox in the microregion of the Alto Médio Gurgueia, South of Piauí, Brazil. Eight animals of the quarter-mile breed and their crossbreed, of different ages, weight and sex, were selected and asked about the time they were engaged in the activity of the vaquejada and the type of training they were submitted to as they practiced running on which side of the ox, in a vaquejada test in the municipality of Cristino Castro, South of Piauí, Brazil, where the participants came from different farms of the microregion of the Alto Médio Gurgueia, South of Piauí, Brazil. The ultrasonography of the IB, IIB and IIIB zones of the superficial digital (TFDS) and deep digital flexor tendons (TFDP) were performed in each animal, obtaining the measurements of the lateral diameters (DML) and palmar dorsum (DDP) through the transverse plane in each of the different zones. Data were submitted to statistical analysis (ANOVA), using the t test at the significance level of (p <0.05), observing that there was no significant difference between the measures evaluated. According to the results, horses for vaquejada athletes do not present significant difference in the lateral diameters and palmar dorsum of the flexor tendons between the right and left thoracic limb antimeres.
