AbstractOccurrence of seropositive sheep (Ovis aries) to Bovine Leukemia Virus (BLV) by agar-gel immunodiffusion test (AGID) using the antigen gp51 was surveyed for the period 2005-2007. Samples were collected from sheep in the Brazilian states of Rio Grande do Sul, Paraná, São Paulo, Pernambuco, Maranhão, Pará, Bahia, Mato Grosso, Rondônia, and Acre. Two of 35 (5.7%) flocks were seropositive to BLV, and the rate of seropositive animals was 0.077% (two of 2,592). The two seropositive sheep were female, one 13-month old Santa Inês breed and other of unknown age and breed, both from the state of São Paulo. Distribution of BLV in the ovine population studied proved to be a rare event in Brazil.
