Detection and determination of Toxoplasma gondii seroprevalence in native Korean goats (Capra hircus coreanae).

Toxoplasma gondii is an important zoonotic protozoan pathogen that causes serious illness in immunocompromised humans and infection in animals worldwide. The current study was conducted for detection of T. gondii infection and determination of the seroprevalence of the pathogen in native Korean goats (Capra hircus coreanae). Analysis of a total of 610 sera samples collected from 60 herds between 2009 and 2011 were performed using a commercial enzyme-linked immunosorbent assay (ELISA) kit for detection of anti-T. gondii IgG antibodies. Among the animals tested, 5.1% (31/610) showed seropositivity for anti-T. gondii antibodies, and 38.3% (23/60) of the herds were seropositive. The prevalence rates between young (<1 year) and adult (≥1 and ≤3 years) goats were 7.0% and 4.1%, respectively, without statistical significance (p>0.05). Likewise, the prevalence rates observed during cold season (October-March) and warm season (April-September) were 2.9% and 5.5%, respectively, without statistical significance. Seroprevalence rates observed in the northern, central, and southern regions were 7.9%, 3.8%, and 4.2%, respectively. In conclusion, we report for the first time on the seroprevalence of anti-T. gondii antibodies in native Korean goats (Capra hircus coreanae). The results of this study also indicate that there is a nationwide distribution of T. gondii infection among goats. Therefore, the implementation of integrated control strategies as well as measures for prevention and control of T. gondii infection within goats is recommended.
