Seroprevalence of Mycobacterium avium subspecies paratuberculosis in Korean black goats (Capra hircus aegagrus)

In total, 582 sera from 116 black goat herds were analyzed by a commercially available ELISA kit to monitor the seroprevalence of Mycobacterium avium subspecies paratuberculosis (Mpt) in Korean black goats (Capra hircus aegagrus). The mean number of goats sampled per herd was 5.11, 4.66, and 5.38 for the northern, central, and southern regions of Korea, respectively. The apparent regional prevalence of Mpt was estimated at 18.2-38.2% and 4.6-15.3% for herds and goats, respectively. The Mpt-positive goats were predominantly detected in the south (n=28), compared to either the northern (n=9) or central (n=11) regions (chi=14.459, P<0.05). Our findings indicate that Mpt is prevalent among the goat population, but regional variation exists.
