摘要：
The prevalence of Brucella antibodies in serum of unvaccinated grazing goats as well as risk factors for brucellosis in northeastern Mexico were evaluated using data from a cross-sectional study between 2002 and 2008. Data were from 99 goat flocks. Serum samples from 12,127 goats were analyzed with the Rose-Bengal plate-agglutination test (RBPT). 9.3% of goats had antibodies against Brucella, and the disease affected 64% of goat flocks. A multiple logistic regression model identified altitude of grazing site (OR = 1.40), average annual precipitation (OR = 1.68), flock size (OR = 1.21) and breed of goats (indigenous goats more resistant than imported ones) as risk factors for seropositivity for Brucella. It was concluded that brucellosis is quite widespread in flocks in the region studied. Also, flocks with <50 goats, low geographical elevation of flock location, increased shrub cover and lower annual rainfall were associated with increased odds of testing positive for Brucella.
