摘 要：There is a lack of information concerning the prevalence of Toxoplasma gondii infection in Liaoning cashmere goats from northeastern China. In the present study, a total of 650 serum samples were collected from 5 counties between May and June 2012 and antibodies to T. gondii were detected by indirect haemagglutination assay(IHA). 58(8.92%) of them were detected positive for antibodies to T. gondii in serum samples, with antibody titres ranging from 1:64 to 1:1024. Seropositive samples were distributed in all 5 counties and seroprevalences in Kuandian county(15.11%, 21/139, 95% confidence interval [CI], 9.15% to 21.06%) were statistically different with other 4 counties(Gaizhou, Huanren, Xiuyan, Liaoyang), and the seroprevalences difference between Xiuyan county(11.81%, 15/127, 95% confidence interval [CI], 6.20% to 17.42%) and other 2 counties(Huanren, Liaoyang) was significant different(P0.05). 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 China.
