Resumo: | The epidemic and clinic-pathological aspects of paratuberculois in a dairy cattle herd in the Rio Claro county, southern Rio de Janeiro region, are described. In the years 2006-2009, eight adult cows presented chronic-intermittent diarrhea, chronic weight loss and normal appetite. At necropsy, the subserosal lymphatics were proeminent and dilated, mesenteric nodes were enlarged, and intestinal mucosa was corrugated, thickened and of microgranular aspect. Especially, in duodenum, was observed polipoids lesions in mucosa surface. Histopathology revealed, from the duodenum to the rectum, severe and diffuse granulomatous inflammation of the lamina propria and submucosa, broadened and distorced villi, marked dilatation of the lymphatic vessels in their apex, lymphangioectasia and granulomatous lymphangitis in the submucosa. Ziehl-Neelsen stain revealed variable amounts of acid-fast bacilli in macrophages, Langhan s giant cells and freely in the musosa and submucosa of the small intestine and colon, and in lymphnodes. Lesions in the lamina propria, particularly in the jejun and ileum, in some animals, were severe hypertrophy; polipoids lesions observed in duodenum mucosa was markedly muscularis mucosa hipertrophy , intestinals and duodenal glands hiperplasia. Mycobacterium avium subsp. paratuberulosis was isolated by bacterial cultivation of samples from feces, intestinal mucosa and milk, and identified through IS900 PCR. From 298 cows, older than three years, the percentage of reactive animals was 40%, in indirect ELISA test. The diagnosis of paratuberculosis was based on clinic-epidemiological data, sorology, bacterial isolation and IS900 PCR. After the adoption of control measures, as slaughter of sick cows and selective slaughter of soropositive animals, was observed reduction of clinical cases in the herd, from six cases to one case per year, in three years of study. |

No per?odo de 2006 a 2009, oito vacas adultas da ra?a Girolanda apresentaram diarreia cr?nico-intermitente, perda de peso progressivo e apetite normal. ? necropsia observou-se vasos linf?ticos subserosos proeminentes, linfonodos mesent?ricos aumentados de volume, ?midos ao corte, serosa do intestino com aspecto anelado e cerebr?ide, mucosa espessada, pregueada e com aspecto microgranular. Em especial, no duodeno havia les?es polip?ides na supef?cie da mucosa. ? microscopia, desde o duodeno at? o intestino grosso, havia acentuada inflama??o granulomatosa difusa, marcada dilata??o dos vasos linf?ticos no ?pice das vilosidades, linfangiectasia e linfangite granulomatosa na submucosa, muscular e serosa, altera??es tamb?m vistas nos linfonodos mesent?ricos. A colora??o de Ziehl-Neelsen revelou, vari?vel quantidade de bacilos ?lcool-?cido resistentes no interior de macr?fagos, c?lulas gigantes de Langhans e livres na mucosa e submucosa do intestino delgado e grosso e em linfonodos mesent?ricos. A l?mina pr?pria da mucosa, principalmente do jejuno e ?leo de alguns animais, apresentava acentuada hipertrofia; as les?es polip?ides correspondiam ? marcada hipertrofia da muscular da mucosa, hiperplasia de gl?ndulas duodenais e intestinais. Mycobacterium avium subsp. paratuberculosis foi isolado em cultivo bacteriano a partir de amostras de fezes, raspado de mucosa intestinal e leite e identificado pela t?cnica de PCR IS900. Atrav?s da avalia??o sorol?gica semestral, foram analisadas 298 vacas, a partir de tr?s anos de idade, e observou-se cerca de 40% de animais reagentes ao teste ELISA indireto no per?odo estudado. O diagn?stico da paratuberculose foi baseado nos dados cl?nicopatol?gicos, sorologia, isolamento e identifica??o do agente em amostras de fezes, raspado de mucosa e leite, atrav?s do cultivo bacteriano e PCR IS900. Ap?s implementa??o de medidas de controle, tais como elimina??o de animais doentes, abate seletivo dos soropositivos, separa??o dos bezerros ao nascer com utiliza??o de banco de colostro, observou-se diminui??o da ocorr?ncia de casos cl?nicos no rebanho, de seis casos por ano para cerca de um caso por ano, em tr?s anos de estudo.Made available in DSpace on 2016-04-28T20:18:25Z (GMT).
