Our results showed that goats had higher seropositivity 49.65% (71\/143, 95%CI: 41.97\u201357.75) followed by sheep 16.67% (15\/90, 95%CI: 10.37\u201325.69) and cattle 3.25% (5\/154, 95%CI: 1.40\u20137.37). Livestock species with a history of abortion had higher seropositivity of 33.89% (goats 57\/62, sheep 4\/62, cattle 1\/62, 95%CI: 27.38\u201341.08) compared to non-aborting from the baseline study (goats 15\/30, sheep 11\/30, cattle 4\/30, 95%CI: 10.34\u201319.93). Conditional logistic regression model identified abortion as a significant risk factor, with goats being 26.71 times more likely to abort than cattle, and sheep 3.59 times more likely than cattle.
