Abstract
ABSTRACT The seroprevalence of Maedi-Visna in sheep from Aracatuba region – SP, was determined and correlated to age, gender, breed, or sheep production systems. Blood samples were collected from 444 sheep, aging from two to 12 year-old. Both sexes and different breeds were sampled in 20 farms of this region. Physical examination was performed in all animals. Agar gel immunodiffusion test kit was used to diagnose in serum samples. Twelve animals, from five different farms, were AGID positive, yielding a seroprevalence of 2.7%, with no correlation among breed, gender, or sheep production systems and the detection of the disease. No animal considered positive for Maedi-Visna showed clinical signs compatible with Maedi-Visna.
