Occurrence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in pigs in the State of Pará, Brazil / Ocorrência de anticorpos contra Toxoplasma gondii e Neospora caninum em suínos no estado do Pará, Brasil

We investigated the occurrence of Toxoplasma gondii and Neospora caninum antibodies in pigs raised in the Northeast of Pará, Brazil. At Study I, convenience sampled 151 pigs at two slaughterhouses, with and without state inspection; and Study II, which assessed 159 pigs with probabilistic sampling from nine pig farms. Serological analysis was performed using indirect fluorescent antibody test for T. gondii and N. caninum with a cutoff of 64 and 50, respectively. Overall, 6.77% pigs were seropositive for T. gondii and 5.16% for N. caninum. In Study I, pigs slaughtered with and without state inspection presented similar occurrence for both coccidia (p>0.05). Study II found an association between N. caninum seropositivity and sludge discarded into the soil, feeding pigs with animal-based protein, subsistence system, and absence of nipple drinkers. No association was found for T. gondii. Pigs from Pará are a potential source of T. gondii infection to humans. To our best knowledge, this is the first study to report anti-N. caninum antibodies in the serum of pigs in Pará State, Brazilian Amazon.(AU)

Foi investigada a ocorrência de anticorpos contra Toxoplasma gondii e Neospora caninum em suínos criados no nordeste do Pará, Brasil. No Estudo I, foram amostrados 151 porcos em dois matadouros, com e sem inspeção estadual. O Estudo II avaliou 159 suínos com amostragem probabilística de nove granjas de suínos. Para sorologia, utilizou-se o teste de imunofluorescência indireta para T. gondii e N. caninum com ponto de corte de 1:64 e 1:50, respectivamente. No geral, 6,77% dos suínos foram soropositivos para T. gondii e 5,16% para N. caninum. No Estudo I, suínos abatidos em matadouros com e sem inspeção estadual apresentaram ocorrência semelhante para ambos os coccídios (p> 0,05). Os animais amostrados de Belém, Benevides, Marituba, Bujaru, Castanhal e Igarapé-Miri foram positivos para T. gondii, enquanto os soropositivos para N. caninum foram encontrados em Belém, Bujaru, Castanhal e Santo Antônio do Tauá. O Estudo II encontrou associação entre soropositividade de N. caninum e esterco descartado no solo, alimentação dos suínos com proteína de origem animal, criação de subsistência e ausência de bebedores tipo nipple. Não foi encontrada associação para T. gondii. A carne suína apresenta potencial risco de transmissão de T. gondii para os habitantes da região. De acordo com nosso conhecimento, este é o primeiro relato de anticorpos anti-N. caninum em suínos no estado do Pará, Amazônia brasileira.(AU)

Infiltrative rectal adenocarcinoma in a dog

Background: Intestinal neoplasms are uncommon in dogs and adenocarcinoma is the main histological type found. Thisneoplasm presents slow growth and high capacity of causing metastasis. Histologically speaking, neoplasm cells can presentsolid, tubular, papillary arrangement and note amorphous extra-cellular material. Clinically observed tenesmus, diarrhea,dyskinesia, hematochezia, mane, protrusion of the anus, weight loss, anorexia. The occurrence and clinicopathologicalaspects of tumors in dogs’ gastrointestinal tract, the rectal segment, remains poorly understood. Accordingly, the aim ofthe present study is to report a case on infiltrative rectal adenocarcinoma diagnosed in a dog.Case: A 7-year-old male dog representative of the Fila Brasileiro breed was presented to the Veterinary Hospital of University Federal Rural of Amazonia, with history of hyperthermia, anorexia, apathy and tenesmus. Imaging examinationsdepicted prostatomegaly. Exploratory laparotomy was performed and showed the thickening and hardening of the rectumsegment. The animal was subjected to euthanasia. Necroscopy showed increased rectal perimeter; the mucosa in its opening presented atypical cerebroid aspect and irregular surface, and areas dark red. The rectal segment depicted a thick wallof white color, irregular limits covering the muscular and adjacent sub-mucosa. The peri-rectal adipose tissue presentedpoor delimitation with the rectum, multiple greyish and reddish areas. Increased prostate and iliac lymph, and multi nodeof regular limits in the lungs. The histology of the rectal tissue depicted epithelium with differentiated neoformation,composed of atypical cells; nuclear anisocytosis, anisocariasis and hyperchromasia placed in small islands, cords or tubular formation. Neoplasm growth was unorganized and of infiltrative character. Some areas presented mucosal patterncells with Signal Ring morphologic. Multiple rectal blood...

Paraganglioma de corpo aórtico em cão / Aortic body paraganglioma in dog

Background: Aortic body paragangliomas are uncommon neoplasms that develop mainly in aortic and carotid bodies. It has been supposed that genetic factors and chronic hypoxia may stimulate tumor development. The brachycephalic dog breeds, as Boxer, are most predisposed to present this neoplasm. The clinical symptomatology is related to tumor size and localization. Usually aortic body paraganglioma has benign biological behavior, when it is malignant, rarely promotes metastases. The aim of this study was to report a case of the aortic body paraganglioma as death cause in a dog. Case: A canine, 10-year-old, male, cross breed, presented clinical signs as anorexia, emesis, cough, dyspnea and exercise intolerance. After death the animal was examined at the Department of Veterinary Pathology at the Federal Rural University of Amazonia. On necropsy, no pericardial effusion was identified, however pleural and abdominal effusion was observed, volume like 1000 and 700 mL, respectively. The heart had a neoplasm near the left atrium, it measured 6.5 x 8.2 cm, had irregular surface, firm consistency, grayish color, and at the cut showed infiltration in the myocardium, as well as obstruction of the left atrial lumen and left ventricle concentric hypertrophy. No distant metastases were found. Microscopically, the tumor consisted of polyhedral morphology cells, eosinophilic cytoplasm, spherical and hyperchromatic nucleus. Cells were grouped into lobes separated by fibrovascular stroma, large cells (less uniform cells), low mitotic rate and myocardial infiltration. On immunohistochemical analysis anti-cytokeratin, anti-vimentin and anti-S-100 antibodies were used. Tumour cells stained was absent for anti-cytokeratin and anti-vimentin, but was anti-S-100 positive. A case of malignant aortic body paraganglioma grade II was diagnosed.[…](AU)

Lesões cutâneas tipo tumorais associadas à infeção por avipoxvirus em uma marreca-cabocla (Dendrocygna autumnalis) / Cutaneous tumor-like lesions associated with infection by avipoxvirus in a Dendrocygna Autumnalis

The fowlpox, also known as contagiosum epithelioma, is caused by a poxvirus of the genus Avipoxvirus and affects both domestic and wild birds. The disease has two forms cutaneous and diphtheria. In March 2008 the sector of rehabilitation of wild birds from Mangual das Garças Park, located in Belém, Pará attended a duck (Dendrocygna autumnalis) that had nodular lesions in regions of the wing devoid of feathers. The lesions consisted of two large cutaneous tumor-like nodules that measured 4,2 x 3,8 cm and 2,8 x 2,2 cm in length and width, respectively. The nodules were surgically removed, fixed in 10% formalin, processed and stained with hematoxylin-eosin. Histopathology showed acanthosis and expressive hyperkeratosis, some cells showed spongiosis. The confirmatory diagnosis of fowlpox was established by the pathognomonic sign of the presence of large intracytoplasmic eosinophilic inclusion corpuscles (Bollinger bodies) in epithelial cells. This is the first report of poxvirus infection in a wild bird in the State of Pará, Brazil.

O setor de reabilitação de aves selvagens do Parque Mangual das Garças, localizado em Belém, Pará, recebeu um espécime de Marreca-cabocla (Dendrocygna autumnalis). O animal apresentava lesões nodulares em regiões desprovidas de penas na asa, que consistiam de dois grandes nódulos cutâneos de aspecto tumoral, que mediram 4,2 x 3,8 cm e 2,8 x 2,2 cm de comprimento e largura, respectivamente. Os nódulos foram removidos cirurgicamente, fixados em formol a 10%, e as amostras foram processadas para histopatologia, coradas pela hematoxilina-eosina. Na análise histopatológica, observaram-se acantose e expressiva hiperceratose; várias células mostraram espongiose. O diagnóstico da bouba foi estabelecido pelo sinal patognomônico da presença de grandes corpúsculos de inclusão eosinofílicos intracitoplasmáticos  (corpúsculos de Bollinger) nas células epiteliais da lesão tumoral. Este é o primeiro relato de infecção por poxvírus em ave selvagen no Estado do Pará, Brasil.

Os dados relacionados aos animais, procedência, identificação, espécie e inspeção post mortem foram levantados com o SIE. Todos os fígados analisados foram considerados unidades experimentais. Nos resultados houve alteração em 29,64% dos fígados analisados, representadas por telangiectasia, esteatose, abcesso, cirrose, tuberculose e peri-hepatite. Estes achados foram superiores ao encontrado na literatura, sugerindo que os animais do estudo estão mais acometidos por problemas hepáticos que levam às condenações do órgão em virtude das condições adversas de manejo e meio ambiente. A telangiectasia foi a causa principal de condenação de fígados (13,23%), mas a tuberculose representada por 1,59% merece ser ressaltada por ser zoonose importante. Não houve diferenças significativas das alterações hepáticas em relação à procedência dos animais, mostrando certa semelhança com
