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.
在本研究中，于2012年5月至6月期间从五个县采集了650只山羊的血清样本，并通过间接血凝试验检测了抗弓形虫抗体；58只（9%）山羊有抗弓形虫抗体，抗体效价为1:64至1:1024。血清阳性样本分布在所有五个县：宽甸县的血清阳性率（15%，21/139，95%置信区间[CI] 9 - 21%）与其他四个县（盖州、桓仁、岫岩和辽阳）在统计学上有差异，且岫岩县（12%，15/127，95% CI 6 - 17%）与其他两个县（桓仁、辽阳）之间的血清阳性率差异显著（P < 0.05）。据我们所知，这是中国辽宁省绒山羊弓形虫暴露血清阳性率的首次报告。我们的结果表明，辽宁绒山羊可能是辽宁省弓形虫传播的潜在宿主。
