In the present investigation, the seroprevalence of Toxoplasma gondii antibodies in 455 Tibetan sheep in Tibet, China, was examined using an indirect hemagglutination test. Of these, 26 (5.7%) Tibetan sheep were seropositive at the cut-off of 1:64 serum dilution. The seroprevalence ranged from 2.2% to 8.9% among Tibetan sheep of <1-yr-old, 1-3-yr-old, and >3-yr-old, but the differences among the age groups were not significant (P > 0.05). The prevalence in male Tibetan sheep (2.8%) was lower than that in female Tibetan sheep (6.6%), but the difference was not statistically significant (P > 0.05). The results of this survey indicated the presence of T. gondii infection in Tibetan sheep, which may cause economic losses to the local livestock industry and which poses a potential threat to human health in this area.
在本研究中，采用间接血凝试验检测了中国西藏455只藏绵羊的弓形虫抗体血清阳性率。其中，在血清稀释度为1:64的临界值时，有26只（5.7%）藏绵羊血清呈阳性。1岁以下、1 - 3岁和3岁以上藏绵羊的血清阳性率在2.2%至8.9%之间，但各年龄组之间的差异不显著（P > 0.05）。雄性藏绵羊的感染率（2.8%）低于雌性藏绵羊（6.6%），但差异无统计学意义（P > 0.05）。本次调查结果表明藏绵羊存在弓形虫感染，这可能给当地畜牧业造成经济损失，并对该地区人类健康构成潜在威胁。
