To better understand the epizootiology of caprine paratuberculosis in the North of Portugal, a crosssectional
study was conducted from 2014 to 2015. The seroprevalence and risk factors for Mycobacterium
avium subsp. paratuberculosis (Map) seropositivity were evaluated. Antibodies against Map were
determined by a commercial ELISA. In 936 sera tested from 56 goat herds, 120 (12.8%, 95% CI: 10.8–
15.1%) goats and 34 (60.7%, 95% CI: 47.6–72.4%) herds were positive. Risk factors for seropositivity
were investigated by logistic regression models. The odds of Map seropositivity were found to be higher
for animals with clinical signs, OR 5 5.1 (95% CI: 2.7–9.6%), animals belonging to herds with previous
wasting disease, OR 5 2.3 (95% CI: 1.1–4.8%), and accumulation of manure in the herd, OR 5 3.1 (95%
CI: 1.7–5.7%). The potential risk factors identified in this study support the current recommendations
for the control of paratuberculosis in these and other animals.
