Summary: | Paratuberculosis is an infectious disease caused by Mycobacterium avium subsp. paratuberculosis (Map) characterized by chronic granulomatous enteritis. The purpose of this work was to report the anatomopathology of three cases of paratuberculosis in autochthonous dairy cattle from Resende, Rio de Janeiro, Brazil. Animals presented characteristic clinical symptoms of paratuberculosis and were seroreactive to ELISA. They were euthanized and necropsied. Small and large intestines, mesenteric lymph nodes and ileocecal valve samples were collected and processed for histopathology and bacteriology. Tissues were fixed in 10% buffered formalin, processed for paraffin inclusion, and stained by HE (haemathoxilin-eosin) and ZN (Ziehl-Neelsen). Macroscopic alterations such as small intestine wall segmental thickness, mucosal hyperaemia, and corrugation were observed. Ileocaecal valve emaciation, evident mesenteric lymphadenomegally, and lymphangiectasy were also present. The main histopathological findings were enteritis, lymphangitis and granulomatous lymphadenitis. Intestinal lesions were mainly restricted to mucosa and submucosa of jejune and ileum, characterized by inflammatory infiltration of lymphocytes, eosinophils, epithelioid macrophages, and scarce giant Langhan’s–type cells. Numerous acid-fast bacilli were observed into macrophages on the top of villi, lamina propria and lymph nodes parenchyma. Anatomopathology was characteristic for the disease and was considered a valuable tool for the diagnosis of paratuberculosis.KEYWORDS: anatomopathology; bovine; Map; paratuberculosis. |

Visamos registrar a anatomopatologia de três casos de paratuberculose em bovinos leiteiros autóctones oriundos de Resende-RJ. Esses animais apresentavam sinais clínicos de paratuberculose e, após teste de ELISA positivo, foram eutanasiados e necropsiados. Amostras de intestino, linfonodos mesentéricos e válvula ileocecal foram colhidas, fixadas em formol neutro tamponado a 10%, processadas e coradas pelo HE (hematoxilina-eosina) e ZN (Ziehl-Neelsen). Alterações macroscópicas, como espessamento da parede do intestino delgado, mucosas congestas e corrugadas, foram observadas. A linfadenomegalia e linfangectasia também foram evidentes, assim como a congestão e edemaciação das válvulas ileocecais. Os principais achados histopatológicos foram enterite, linfangite e linfadenite granulomatosas. As lesões intestinais se resumiam à mucosa e submucosa, principalmente do jejuno e do íleo e caracterizavam-se por infiltrado inflamatório de linfócitos, eosinófilos e macrófagos epitelióides. A coloração de ZN demonstrou bacilos álcool ácido resistentes (BAAR) nos macrófagos, no ápice das vilosidades e lâmina própria e, ainda, no parênquima dos linfonodos mesentéricos. A anatomopatologia foi característica e considerada uma valiosa ferramenta no diagnóstico da paratuberculose.PALAVRAS-CHAVE: anatomopatológico; bovino; Map; paratuberculoseUniversidade Federal de Goiás2012-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/549010.5216/cab.v13i2.5490Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 13 No. 2 (2012); 228-233Ciência Animal Brasileira / Brazilian Animal Science; v. 13 n. 2 (2012); 228-2331809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/5490/11158https://revistas.ufg.br/vet/article/view/5490/11159Rodrigues, Ana Bárbara F.Ristow, Paula C.
