Resumo
A Secretaria de Defesa Agropecuária estabeleceu o controle e erradicação de Maedi-Visna no Brasil, que inclui o diagnóstico laboratorial e sacrifício dos animais positivos. Com o objetivo de se determinar a ocorrência de Maedi-Visna em ovinos na região de Araçatuba-SP, foram coletadas 444 amostras de sangue de ovinos com idade entre dois e 12 anos, de ambos os sexos e de diversas raças, em 20 propriedades desta região escolhidas aleatoriamente. Exame físico geral foi feito em todos animais, incluindo-se freqüência cardíaca (FC), freqüência respiratória (FR) e temperatura retal (TR), afim de diagnosticar sinais clínicos compatíveis com a doença. Utilizou-se o kit para diagnóstico de Maedi-Visna (IDGA - Imunodifusão em gel de ágar) em amostras de soro. Doze animais reagiram positivamente ao teste, em cinco rebanhos distintos. Não houve associação significante entre prevalência da doença e a raça acometida, o sexo dos animais, os tipos de criação e nem entre as variáveis FC, FR e TR. A prevalência da doença foi de 2,7% sendo que nenhum animal positivo apresentou sinais clínicos compatível com Maedi Visna.
The Agriculture Council established measures for control and erradication of Maedi-Visna in Brazil, by the diagnosis and sacrifice of positive animals. The goal of this study was to determine the occurrence of Maedi-Visna in sheep in Araçatuba region – SP. Blood samples were collected from 444 sheep, age range of 2-12 years old, of both sexes and of various breeds, in 20 farms, aleatorily chosen, in this region. Physical examination was performed in all animals, including heart rate, (HR) respiratory rate (RR) rate and rectal temperature (RT) to diagnose the clinical signs compatible with the disease. Agar gel immunodiffusion test (AGID) kit was used to diagnose Maedi-Visna (Biovetech, Pernambuco, Brasil) in serum samples. Twelve animals were positive on the test in 5 different herds. There was no significant interatction between disease prevalence and the breed affected, sex, types of breeding, and HR, RR, or RT. The prevalence of the disease was 2.7% and no animal considered positive for Maedi-Visna showed clinical signs compatible with Maedi-Visna.
