is an intracellular protozoan parasite which can cause abortion and stillbirth in ruminants. However, there is no information on Tibetan sheep infection in China. A total of 2187 serum samples were collected from Tibetan sheep in the major production areas of Luqu, Maqu, and Tianzhu in Gansu province, and Nyingchi in southeast Tibet, China. All samples were analyzed for the presence of antibodies to using a competitive-inhibition enzyme-linked immunoassay. Of the 2187 serum samples, 184 (8.4%, 95% CI 7.3-9.6) were tested seropositive. The seroprevalence ranged from 4.4% (95% CI 1.4-7.4) to 11.3% (95% CI 8.2-14.4) among different regions, seasons, ages, and pregnancies, and there was no statistical significance among those groups ( > 0.05). Seroprevalence in male (10.8% 69/638) (95% CI 8.4-13.2) was significantly higher than in female (7.4% 115/1549) (OR =1.51, 95% CI 6.1-8.7) ( < 0.01). To our knowledge, this is the first report of seroprevalence in Tibetan sheep in China, which provides baseline data for the prevention and control of infection in Tibetan sheep.
绵羊泰勒虫病是一种由细胞内原生动物寄生虫引起的疾病，可导致反刍动物流产和死胎。然而，目前在中国尚未有关于藏绵羊感染的信息。本研究共采集了来自中国甘肃省碌曲、玛曲和天祝以及西藏东南部林芝主要产区的 2187 份藏绵羊血清样本，使用竞争抑制酶联免疫吸附试验（cELISA）检测这些样本中是否存在针对绵羊泰勒虫的抗体。在 2187 份血清样本中，有 184 份（8.4%，95%置信区间 7.3-9.6）呈血清阳性。不同地区、季节、年龄和妊娠状态下的绵羊泰勒虫血清阳性率在 4.4%（95%置信区间 1.4-7.4）至 11.3%（95%置信区间 8.2-14.4）之间，组间差异无统计学意义（>0.05）。雄性（10.8%，69/638）（95%置信区间 8.4-13.2）的血清阳性率明显高于雌性（7.4%，115/1549）（OR=1.51，95%置信区间 6.1-8.7）（<0.01）。据我们所知，这是中国首次报道藏绵羊绵羊泰勒虫血清阳性率，为藏绵羊绵羊泰勒虫感染的防控提供了基线数据。
