Seroprevalence of Toxoplasma gondii infection in Liaoning cashmere goat from northeastern China

In the present study, serum samples from 650 goats were collected from five counties between May and June 2012 and antibodies to Toxoplasma gondii were detected by indirect haemagglutination assay; 58 (9%) had antibodies to T. gondii with antibody titres of 1:64 to 1:1024. Seropositive samples were distributed in all five counties: seroprevalences in Kuandian county (15%, 21/139, 95% confidence interval [CI] 9–21%) were statistically different from the four other counties (Gaizhou, Huanren, Xiuyan and Liaoyang), and the seroprevalence difference between Xiuyan county (12%, 15/127, 95% CI 6–17%) and two other counties (Huanren, Liaoyang) was significantly different (P < 0.05). To our knowledge, this is the first report of the seroprevalence of T. gondii exposure in Liaoning cashmere goat in China. Our results indicated that Liaoning cashmere goat could be a potential reservoir for the transmission of T. gondii in Liaoning Province
