Susceptibilidade a antimicrobianos de bactérias isoladas de leite caprino em Sergipe - Brasil / Antimicrobial susceptibility of bacteria isolated from goat milk in Sergipe - Brazil

Background: Bacterial resistance is a fundamental aspect of One Health, which is defined as the inseparable unity of animal, human, and environmental health. Epidemiological surveillance on the spread of bacterial resistance in animals and their derived products is essential given that meat, milk, and dairy products can carry resistant microorganisms that may reach humans through the food chain either by direct consumption or by handling the product. To eliminate the scarcity of information, it is necessary to characterize the epidemiological situation in terms of bacterial resistance in dairy production in northeastern Brazil. Thus, the objective of this study was to determine the frequency and antimicrobial susceptibility profile of bacteria isolated from goat milk samples from some municipalities in the Brazilian state of Sergipe. Materials, Methods & Results: The study included 28 goat farms in 4 municipalities of the Semiarid region of the State of Sergipe in Northeastern Brazil, namely Canindé de São Francisco (n = 11), Nossa Senhora da Glória (n = 6), Poço Verde (n = 6), and Porto da Folha (n = 5). All lactating does of each herd (n = 263) aged >1 year were, sampled randomly by non-probabilistic convenience sampling. Milk samples were collected from both teats, resulting in 526 samples in total. Bacterial culturing and isolation were performed, followed by antimicrobial susceptibility profile analysis to the following active principles: amoxicillin with and without clavulanic acid, amikacin, ampicillin with sulbactam, ciprofloxacin, cefalexin, cefalotin, ceftriaxone, chloramphenicol, doxycycline, enrofloxacin, gentamicin, levofloxacin, ofloxacin, penicillin G, and tetracycline. A survey form was used to obtain zootechnical information for each farm. Data are described as absolute and relative frequencies. The significance assessment of the differences between herd characteristics and bacterial isolation was performed using Pearson's chi-squared test. Bacterial isolation occurred in 15.4% (81/526) of the samples from 23.2% (61/263) of the goats. Escherichia coli (45.9% = 28/61), Staphylococcus caprae (16.4% = 10/61) and Enterococcus faecalis (11.5% = 7/61), were the most frequently isolated species. Bacterial isolations were predominant in dairy herds with up to 50 animals, production of 20 to 50 L/day and in the municipality of Porto da Folha. In terms of antimicrobial susceptibility, most isolates demonstrated resistance to penicillin and amoxicillin (88.5%), followed by ceftriaxone (23%), ofloxacin (23%), tetracycline (23%), doxycycline (19.7%), chloramphenicol (11.5%), levofloxacin (11.5%), ampicillin/ sulbactam (8.2%), amikacin (6.6%), cephalothin (4.9%), cephalexin (3.3%) and gentamicin (3.3%). Approximately 20% of the isolates were multidrug resistant, especially E. coli (50%) and S. aureus (16.7%). Discussion: E. coli was the most frequently isolated species from the samples. It is considered an environmental pathogen, and its high frequency in different herds indicates poor milking hygiene. E. coli also stood out as the species presenting the most multidrug-resistant (MDR) isolates (50%), with strains resistant to beta-lactams, aminoglycosides, quinolones, tetracycline, and chloramphenicol. Coagulase-negative staphylococci are recognized as a public health problem as they are etiological agents of various diseases and can easily acquire antimicrobial resistance genes. Although it was not the most frequently isolated species, S. aureus was the species with the second-highest frequency of MDR strains. The presence of MDR species is relevant and indicates the need for urgent action to reduce the dissemination of antimicrobial resistance. Relevant steps must be taken jointly by professionals involved in human, animal, and environmental health.

Occurrence of anti-Brucella abortus agglutinins in small ruminants in Sergipe / Ocorrência de aglutininas anti-Brucella abortus em pequenos ruminantes de Sergipe

The objective this study was to evaluate the occurrence of small ruminants seropositive for Brucella abortus in Sergipe, Brazil. Samples of sheep (1,200) and goats (675) serum blood was collected from 101 farms of 25 counties of the three mesoregions of the state. The technique of Acidified Buffered Acid stained with Rose Bengal (RB) was used and all samples confirmed a positive result using the 2-Mercaptoethanol technique. Four (0.21%) seropositive animals were diagnosed by technique AAT stained with RB, three sheep's (0.25%) and a goat (0.15%), were confirmed by the 2ME test. In all the positive properties, the intercropping of small ruminants with cattle was adopted, favoring the contact with the agent. The prevalence of anti-B. abortus antibodies in herds of small ruminants in Sergipe is described for the first time, and is low, however, it is important to identify seropositive animals to be discarded due to their zoonotic potential.(AU)

Objetivou-se avaliar a ocorrência de pequenos ruminantes soropositivos para Brucella abortus em Sergipe, Brasil, a partir de 1.200 amostras de soro sanguíneo de ovinos e 675 de caprinos, oriundos de 101 propriedades de 25 municípios das três mesorregiões do estado, nas quais foi empregada a técnica do Antígeno Acidificado Tamponado (AAT) corado com Rosa Bengala (RB) como triagem e do 2-Mercaptoetanol (2ME) como confirmatória. Foram diagnosticados 4 animais (0,21%) soropositivos pela técnica de AAT corado com RB, 3 ovelhas (0,25%) e 1 cabra (0,15%), que posteriormente foram confirmados pelo teste de 2ME. Em todas as propriedades positivas era adotada a criação consorciada de pequenos ruminantes com bovinos, favorecendo o contato com o agente causador. A ocorrência de anticorpos anti-B. abortus em rebanhos sergipanos de pequenos ruminantes é descrita pela primeira vez, e mostra-se baixa; entretanto, é importante a identificação de animais soropositivos para que sejam descartados, devido seu potencial zoonótico.(AU)

Squamous cell carcinoma in chinese hamsters (Cricetulus griseus)

Background: The companion animal market has changed over the years. The number of people living in small apartments has increased; as a result, the demand for small pets such as exotics, fish, and small rodents has also increased due to their smaller space requirements and ease of handling and care. Pets help relieve anxiety and stress in people suffering from social issues. Small rodents are usually bred in specific cages with cellulose or wood shaving bedding, and fed with commercially available diets. Small rodent clinics struggle due to the lack of scientific reports on some diseases and therapies. To date, the oncology literature is too limited to develop better diagnosis and treatment methods. Here, we report three cases of squamous cell carcinoma in the mandibular region of Chinese hamsters (Cricetulus griseus).Case: Three adult male hamsters averaging 1.5 years old, from different pet stores, bred under home conditions by different owners in Sergipe, Brazil, were brought to the Dr. Vicente Borelli Hospital at Pio X University for exotic veterinary care. Each animal had been bred alone in a specific breeding cage. Each had a history of apathy, loss of appetite, and rapid deformity of the facial region. Radiographs showed areas of bone involvement and extensive injury, with partial resorption of the left ramus and angle of the mandibular region. Due to the location of the tumor mass, the clinical status, and limitations in systemic treatment, euthanasia was recommended for each animal. After anamnesis, the animals were subjected to clinical assessment. A firm and well-circumscribed mass was identified on palpation. In case A, it compromised the left mandible from the angle to the body and extended to the maxillary soft tissues and left superior lips. In case B, it extended from the ramus to the symphysis on the left side and to the maxillary region, similar to case A.[...]

Clinical, pathological, and immunohistochemistry characterization of toxoplasmosis in dogs with distemper in the semiarid region of Paraíba, Brazil / Caracterização clínica, patológica e imuno-histoquímica da toxoplasmose em cães com cinomose no semiárido da Paraíba, Brasil

The objective of this study was to describe the clinical, pathological, and immunohistochemistry characteristics of five cases of toxoplasmosis, an infection often associated with distemper in dogs. From January 2000 to December 2012, a retrospective study was performed analyzed dogs with distemper in the semiarid region of Paraíba. We evaluated this sample to focus on individuals who presented with concomitant structures in protozoa characteristics, and performed immunohistochemistry (IHC) tests using polyclonal anti-Toxoplasma gondii antibody. In all cases, the clinical signs were similar including digestive changes, as well as respiratory, neurological, and ocular lesions, suggesting an infection of canine distemper virus. The diagnosis of distemper was confirmed on histopathological analysis depending on the presence of intranuclear and intracytoplasmic eosinophilic inclusion bodies in different tissues. Histopathological examination also revealed the characteristic presence of parasitic cysts T. gondii in the brain in four cases, and in the lung in one case. The brain cysts were associated with multifocal areas of malacia and lung there was alveolar septa thickening due to infiltration of macrophages, lymphocytes, and plasma cells, with moderate proliferation of type II pneumocytes and coalescing multifocal areas of necrosis. These cysts are characterized by round and strongly basophilic structures, measuring approximately 5 to 70 μm, delimited by thin wall, stained by hematoxylin and eosin, and immunomarked as brown by immunohistochemistry (IHC) using the chromogen DAB. The diagnosis of toxoplasmosis associated with infection by canine distemper virus in the five case studied was based on microscopic findings and confirmed by immunohistochemistry. Toxoplasmosis should be included in the differential diagnosis of dogs with severe progressive systemic signs, especially when respiratory and neurological involvement is suspected.(AU)

Objetivou-se com este trabalho descrever as características clínicas, patológicas e imuno-histoquímica de cinco casos de toxoplasmose associados à cinomose em cães no semiárido da Paraíba. Para isso, foi realizado um estudo retrospectivo durante o período de janeiro de 2000 a dezembro de 2012, sendo identificados e selecionados os casos de cães com cinomose. Destes, foram avaliados os que apresentavam concomitantemente estruturas características de protozoários e realizada a imuno-histoquímica (IHQ) com anticorpo policlonal anti-Toxoplasma gondii. Em todos os casos os sinais clínicos foram semelhantes e sugestivos de infecção pelo vírus da cinomose canina, variando de alterações digestivas, respiratórias, neurológicas e lesões oculares. O diagnóstico de cinomose foi confirmado na histopatologia através da presença de corpúsculos de inclusões virais eosinofílicos intranucleares e intracitoplasmáticos em diferentes tecidos. O exame histopatológico revelou ainda a presença dos cistos parasitários característicos de T. gondii no encéfalo em quatro casos e no pulmão em um caso. No encéfalo os cistos estavam associados a áreas multifocais de malacia e no pulmão havia espessamento dos septos alveolares por infiltrado de macrófagos, plasmócitos e linfócitos, com proliferação moderada de pneumócitos tipo II e áreas multifocais a coalescentes de necrose. Esses cistos caracterizaram-se por estruturas arredondadas fortemente basofílicas medindo aproximadamente de 5 a 70 μm, delimitadas por uma fina parede pela hematoxilina e eosina e na IHQ foram fortemente imunomarcados em marrom para T. gondii. O diagnóstico de toxoplasmose associado à infecção pelo vírus da cinomose nos cinco casos estudados foi baseado nos achados microscópicos e confirmado através da imuno-histoquímica. A toxoplasmose deve ser incluída no diagnóstico diferencial de cães com sinais sistêmicos progressivos severos, principalmente quando há envolvimento respiratório e neurológico.(AU)

Neoplasias de cães e gatos na Paraíba

As neoplasias em cães e gatos são causas frequentes de morte na Paraíba. Essa dissertação é formada por dois artigos originais: o primeiro, submetido à Pequisa Veterinária Brasileira, relata a frequência de neoplasias diagnosticadas em cães e gatos no Hospital Veterinário da Universidade Federal de Campina Grande, Patos, Brasil, entre 2003 e 2010. Para tal, foram revisados todos os protocolos de necropsias e biópsias realizadas no Laboratório de Patologia Animal da referida instituição. As neoplasias mais frequentes em cães ocorreram na pele e anexo (46,1%), seguido da glândula mamária (24,4%), sistema genital (9,6%) e sistema alimentar (6,9%). Os tumores malignos foram mais frequentes que os benignos (p=0,001), representando 78% e 22% respectivamente. Em gatos, a frequência de neoplasias de pele e glândula mamária foram idênticas (39,4% cada), seguidas das do sistema digestivo (8,5%) e fígado (5,7%); os tumores malignos representaram 95,8% dos tumores diagnosticados nesta espécie. O segundo artigo, aceito para publicação na Veterinary Parasitology, relata a associação da infecção por Platynosomum fastosum com o desenvolvimento de colangiocarcinomas em gatos. P. fastosum é um trematódeo das vias biliares de felinos, geralmente encontrado como achado de necropsia. No início da década de 1980, no Brasil, foi associado à colangiocarcinomas, mas este achado não foi confirmado nas numerosas publicações sobre o parasita nos últimos 30 anos. Durante o período de 2000 a 2011, no Hospital Veterinário da Universidade Federal de Campina Grande, no nordeste do Brasil, foram necropsiados 348 gatos, dos quais 11 (3,16%) apresentaram lesões causadas por P. fastosum e presença do parasito. [...] Além disso, são necessários estudos, que determinem os fatores epidemiológicos envolvidos no desenvolvimento dos tumores que acometem os cães e gatos, nas diferentes regiões, a fim de serem tomadas medidas para diminuir a ocorrência e letalidade das neoplasias.

Neoplasms in dogs and cats are a frequent cause of death in Paraíba. This dissertation is formed by two papers. In the first paper, send for publication to the Brazilian Journal of Veterinary Research reports the frequency of neoplasm diagnosed in dogs and cats at the Veterinary Hospital of the Federal University of Campina Grande in Patos, northeastern Brazil, between 2003 and 2010. All necropsy and biopsy protocols from the pathology laboratory were revised and data related to the tumors were analyzed. Tumors of the skin and anexa were the most frequently diagnosed (46.1%), followed by tumors of the mammary gland (24.4%), genital system (9.6%), and alimentary system (6.9%). Malignant tumors (78%) were more frequent than bening tumors (22%) (p=0.001) In cats the frequency of skin and mammary gland tumors was the same (39.4%), followed by tumors of the digestive system (8.5%) and liver (5.7%). In cats, 95.8% of the tumors were malignant. The second paper, accepted for publication on the veterinary Parasitology reports the association between Platynosomum fastosum infection and cholangiocarcinomas in cats. P. fastosum is a feline biliary tract trematode that generally causes asymptomatic infections. In the early 1980s in Brazil, P. fastosum was associated with cholangiocarcinomas, but this finding was not confirmed in the various publications on the parasite during the last 30 years. From 2000 to 2011, in the Veterinary Hospital of the Federal University of Campina Grande in northeast Brazil, 348 cats were necropsied, 11 of which (3.16%) were parasitized by P. fastosum. [...] As a result, the systematic histologic diagnosis and the determination of the epidemiology of the tumors, in the different regions, are necessary to decrease tumor mortality.

Avaliação clínica, hematológica e parasitária em equinos de tração na cidade de Aracaju, Sergipe / Clinical, hematological and parasitological evaluation in equines used for wagon traction in Aracajú city, SE, Brazil

Com o objetivo de estimar as condições gerais de saúde dos equinos de tração utilizados na cidade de Aracaju-SE, foram realizadas avaliações clínico-laboratorial em 50 destes animais, atendidos no hospital veterinário da Faculdade Pio Décimo no período de agosto a dezembro de 2008. Na avaliação clínica constatou-se aumento da frequência respiratória e cardíaca em 36% e 30% dos cavalos, respectivamente. Lesões de pele estavam presentes em 5% dos animais e incluíam alopecia, escoriações, crostas e feridas. Houve presença de ectoparasitas (carrapatos) em 54% dos equinos. As alterações patológicas nos membros como tenossinovite, tendinite, aumento de volume articular e claudicação, bem como rachaduras e fissuras nos cascos, casqueamento e ferrageamento inadequados, foram observadas em 46% dos animais avaliados. Endoparasitos estavam presentes em 58% dos animais avaliados, sendo os estrôngilos os mais prevalentes. Entre estes, 34,48% possuíam um elevado grau de parasitismo. Os resultados obtidos sugerem que os equinos de tração urbana da referida cidade apresentam deficiências de manejo que levam a patologias e que comprometem a capacidade de trabalho, a saúde e o bem-estar destes animais, sendo necessária a adoção de medidas que visem minimizar os problemas advindos desta atividade.

To estimate the general health condition of traction equines used in the Aracaju city, Sergipe state, Brazil, clinical laboratory evaluations were performed on 50 horses attended in the veterinary hospital of Faculdade Pio Décimo, from August to December, 2008. At clinical evaluation 36% and 30% increase of respiratory and cardiac frequencies, respectively, was found. Skin lesions were present in 5% of the animals including alopecia, abrasion, crusts and wounds. Ectoparasites (ticks) were present in 54% of the equines. Pathological disorders of the locomotor system, as tenosynovitis, tendinitis, joint swelling, claudication, hoof cracks, inadequate trimming and shoeing were observed in 48% of the horses. Endoparasites were present in 58% of the horses and the Strongyloides were more prevalent. Among these horses, 34.48% had high degree of parasitism. The results indicate that urban traction horses in the referred city have handling deficiency that induces pathologies and compromises animal work capacity, health and welfare, and requires actions to minimize problems resulting from this activity.
