ABSTRACT
Serum samples (n = 1532) were collected between May 2011 to April 2012 from goats from 76 herds (49 from dairy farms and 27 herds for genetic improvement) from three geographical regions from the state of Pernambuco, Brazil Zona da Mata, Agreste, and Sertão. Samples were processed using agar gel immunodiffusion test, with p28 CAEV antigen. The objective was to determine the risk factors for small ruminant lentivirus (SRLV) in dairy goats and goats with high genetic value. Overall, seroprevalence was 13.7% (210/1532) [95% CI 12-15.4%] in animals and 67.1% (51/76) [95% CI 56.5%- 77.7%] in herds. In dairy farms the seroprevalence was 73.5% (36/49) [95% CI 61.1%- 85.8%], and in properties with animals of high genetic value it was 55.6% (15/27) [95% CI 36.8%- 74.3%]. Robust Poisson regression analysis adjusted by the random effect of the herd showed that risk factors were importing bucks from another Brazilian state (prevalence ratio [PR] = 4.73 [95% CI 2.05; 10.88]), not isolating sick animals (PR = 3.27 [95% CI 2.24; 4.76]), and participating in fairs/animal crowding (PR = 1.52 [95% CI 1.09; 2.11]). Prevalence results show that SRLV is present in caprine herds in the state of Pernambuco and identified risk factors are strongly related to animal transit. Considering the epidemiological situation, the first step for mitigating the consequences of this disease would be controlling animal transit.
