The prevalence of small ruminant lentivirus (SRL) infection was evaluated in goats and sheep in two counties of Pernambuco State, Brasil. Seriological examinations were performed from a total of 672 goats and 325 sheep, one year of age and older, at two abattoirs. Sera were analyzed by agar gel immunodiffusion using Maedi-Visna K-1514 antigens. There were 42 reactive samples (95% confidence interval 3.6% to 4.9%) in both slaughter houses. In São Lourenço da Mata county, 3.2% and 4.0% of goat and sheep sera were responsive, whereas in Paulista county, 5.1% of goat samples and 8.2% of sheep were reactive. Thus, the prevalence of small ruminant lentivirus was low in goats and sheep sampled from the region.(AU)
