Leishmaniose visceral em cães / Visceral leishmaniasis in dogs

Background: Canine visceral leishmaniasis (CVL) is a zoonosis of variable clinical presentation, either in systemic orcutaneous form. Clinical signs include anorexia, ophthalmopathies, and chronic kidney disease. In the state of Santa Catarina, the foci are concentrated in the capital and its adjacencies, in the east side of the state. The objective of this studyis to outline the first three reported cases of CVL in the municipality of Curitibanos, since there are no reports to date inthe region of the mountainous plateau, in the middle west of Santa Catarina.Cases: All dogs were treated at the Veterinary Clinic School of the Federal University of Santa Catarina, Campus Curitibanos. The animals, two males and one female, belonged to the same tutor, resided in Curitibanos, and were attendedbetween 2016 and 2020. In the first case, attended in 2016, the complaint was of eye and skin changes about three monthsago. The animal lived in an urban environment and came from Uruguaiana, Rio Grande do Sul. On physical examination,the animal presented skin peeling, wet and crusty lesions, bloody discharge in the ears and nasal hyperkeratosis, as wellas signs suggestive of uveitis. In this case, euthanasia was carried out. The second case had complaints of respiratory, eyechanges, hyporexia, and polydipsia. The dog was prostrate, dehydrated, with lymphadenomegaly and respiratory disorders, compatible with bacterial pneumonia. Bilateral corneal edema confirmed uveitis. Upon return, the animal remaineddehydrated with enlarged lymph nodes. In the aspiration of the lymph nodes, suggestive forms of Leishmania sp. wereobserved. The recommended confirmatory tests were performed, leading to a definitive diagnosis of CVL. The patientwas treated with miltefosine, but later died. The third case was attended for general evaluation after a positive diagnosisfor CVL during an epidemiological survey of the second case. The animal was alert, tachycardic, and tachypneic with...(AU)

Feline plasm cell pododermatitis: case report / Pododermatite plasmocitária felina: relatode caso

Feline Plasmacytic Pododermatitis is an uncommon dermatological disorder that affects one or multiple paw pads and leads to swelling, ulceration, hemorrhage, scaling, erythema, and striation. Its etiopathogenesis is poorly understood, however, an immune-mediated basis is strongly suggested. A two-year-old neutered, mixed breed, male cat was referred to the Veterinary Clinic of the Federal University of Santa Catarina (UFSC), Curitibanos Campus, with a brief clinical history of progressive lesions on palmar and plantar pads for one month. On physical examination, the patient had enlarged popliteal and inguinal lymph nodes, and paw pads with thin, swollen, hyperemic, erythematous, and purple color skin with multiple white striations. Histopathological diagnosis confirmed plasmacytic pododermatitis, and glucocorticoid therapy with prednisolone was prescribed. In the present report, the patient's clinical follow-up was compromised, as the tutor did not perform the prescribed treatment and did not return with the animal for further evaluations.

A pododermatite plasmocitáriafelina é uma desordem dermatológica incomum que acomete os coxins plantares e/ou palmares, levando a edema, ulceração, hemorragia, descamação, eritema e estrias esbranquiçadas. Sua etiologia e patogenia são desconhecidas, mas acredita-se que tenha origem imunomediada. Foi atendido na Clínica Veterinária Escola da UFSC, CampusCuritibanos, um felino, macho, sem raça definida, 2 anos de idade, castrado, com histórico de lesões nos coxins palmares e plantares há um mês, com evolução progressiva. Ao exame físico apresentava-se com os linfonodos poplíteos e inguinais aumentados, além de coxins com pele fina, edemaciada, hiperêmica, com eritema, púrpura e estrias esbranquiçadas. O diagnóstico histopatológico confirmou pododermatite plasmocitária e foi prescrito tratamento à base de prednisolona. Não foi possível acompanhar a evolução clínica do paciente, pois o tutor não realizou o tratamento prescrito e não trouxe o animal para novas avaliações.

Deaths of Cows During Long Distance Transportation to the Slaughterhouse. Changes on Histopathological Examination, Muscle and Liver Glycogen Storage and Muscle pH

The present experiment aimed to perform histopathological, muscle and liver glycogen and muscle pH analyses ofcows dead during transportation, and submitted to necropsy in slaughterhouses inspected by Federal Agencies, in Araguaína– TO, Brazil, from January to July 2013. Six affected animals dead during transportation and submitted to necropsyconstituted the Experimental Group (EG); a Control Group (CG), was composed by 6 cows slaughtered ordinarily followingthe slaughter flow. Gross and histopathological evaluations were accomplished only on EG. The main gross lesionsobserved at necropsy were extensive subcutaneous and muscle hemorrhage and hematomas, interstitial (83.3% of cases) andalveolar (66.6% of cases) lung emphysema, lung congestion (66.6% of cases) and edema (16.6% of cases), kidney (83.3%of cases) and liver congestion (16.6% of cases). On histopathological evaluation, the lungs showed interstitial (100% ofcases) and alveolar emphysema (66.6% of cases), congestion (66.6% of cases), edema (16.6% of cases) and blood aspiration(16.6% of cases). Renal congestion (83.3% of cases), hyaline casts (50% of cases) and tubular degeneration were thekidneys changes (16.6% of cases). Rarefaction of the white pulp (66.6% of cases), red pulp (66.6% of cases) andhemosiderin (16.6% of cases) were detected on spleen. The hepatocytes showed turve and finely vacuolyzed cytoplasm(lace-like aspect) possibly caused by a reduction on glycogen (50% of cases) and congestion (16.6% of cases). Autholysiswas observed on 50% of the livers and 16.6% of the spleens and kidneys. The animals from the EG presented higher meanof degenerate muscle fibers. The intercostal muscle was more affected when compared with other muscles on the samegroup. Muscle pH values were higher on EG than on CG. Differently, glycogen average values were similar between groups(EG 58.97 µmol/g and CG 57.05 µmol/g)[...]

Pesquisa de genes de virulência em Salmonella Hadar em amostras provenientesde material avícola / Survey of virulence genes in Salmonella Hadar in materials coming from chickens

A salmonelose é uma das mais importantes zoonoses, mundialmente reconhecida por sua implicação em saúde pública e também por resultar em perdas econômicas na produção animal. O resultado das infecções por Salmonella é determinado pelo status do hospedeiro e o status da bactéria. Enquanto idade, genética e fatores ambientais podem determinar o status do hospedeiro, o status das bactérias é determinado pelos chamados fatores de virulência. No presente trabalho foram pesquisados três genes de virulência relacionados à Salmonella, os genes fimbriais invA, agfA e lpfA. Foram testadas 45 amostras isoladas a partir de mecônio, carcaças e cortes de frango no Rio Grande do Sul, pelo Centro de Diagnóstico e Pesquisa em Patologia Aviária (CDPA) da Universidade Federal do Rio Grande do Sul (UFRGS) Os testes foram feitos através da Reação em Cadeia pela Polimerase (PCR) e as leituras foram feitas em gel de agarose a 1,2% corados com brometo de etídio e visualizados sob luz ultravioleta. Os resultados obtidos mostram a presença dos três genes em todas as amostras de Salmonella Hadar testadas

Salmonelosis is one of the most important zoonosis, recognized in the entire World for its importance in public health, and resulting in economic lost in animal production. The results of Salmonella infection is determined by the host status and the status of bacteria. While age, genetic and environmental factors can determine the status of the host, the status of bacteria is determined by the called virulence factors. In this work tree genes were analyzed, the genus invA, agfA and lpfA. 45 samples were tested , isolated from carcass, parts of carcass and feces samples in Rio Grande do Sul, by the Centro de Diagnóstico e Pesquisa em Patologia Aviária (CDPA) from Universidade Federal do Rio Grande do Sul (UFRGS). The tests were made by the Polymerase Chain Reaction (PCR) and the reads were made in 1,2% agarose gel colored with etidium bromet and analyzed in UV light. Results show the presence of all three genes in all samples of Salmonella Hadar tested
