摘要 为了解甘肃天祝藏族自治县牦牛弓形虫病流行情况,为制定科学防控措施提供参考数据,本次调查采用间接血凝法对该地区12个乡镇的397份牦牛血清进行了弓形虫抗体检测。结果显示,该地区牛群弓形虫血清抗体阳性率平均为24.18%,最高和最低的两个地区分别是赛什斯镇和毛藏乡,不同乡镇间的牦牛血清弓形虫抗体感染率有显著性差异(P<0.05);雌性牦牛的弓形虫血清抗体阳性率略高于雄性;不同年龄比较,年龄小于3岁的牦牛阳性率最高。结果表明,该地区牦牛弓形虫病流行较为普遍,应引起重视。 To well understand the information on epidemiology of Toxoplasma gondii infection in yaks in Tianzhu Tibetan autonomous county of Gansu Province and set out the prevention and control measures, the indirect agglutination test(IHAT) were used to examine the 397 yak serums which from twelve rural towns in Gansu Province. In the study, the seroprevalence of T. gondii in yak was 24.18%. Among of them, the infection of T. gondii in Saishensi township was the highest, but Maozang township was the lowest, and the difference was statistically significant(P〈0.05). The seroprevalence in female was slightly higher than that in male. The highest seropositive group was determined at yaks less than 3 years old. The results indicated that T. gondii infection was prevalent in yak in Tianzhu tibetan autonomous county of Gansu Province, which implication for the public health concern in this region should be warned.
