Abstract:

牛环形泰勒虫病是由牛环形泰勒虫(Theileria annulata)寄生于牛类动物的红细胞和网状内皮系统内所引起的蜱传性血液原虫病。临床表现为高热、贫血等重剧症状，若诊治不及时死亡率极高经济损失巨大。本文采用PCR诊断方法对采集于塔什库尔干县的30份牦牛血样进行牛环形泰勒虫病检测。结果显示，PCR检测总体阳性率为13.3% (4/30)，母牦牛阳性率为13.0%，公牦牛阳性率为14.0%，经方差分析发现该病在牦牛性别之间感染率不显著(P = 0.935 > 0.05)，说明该县高原牦牛在不同程度地感染牛环形泰勒虫病，具有潜在危害，应该加强防范。
Bovine ring typhus is a rumorous blood protozoosis caused by the erythrocytes and reticuloendothelial system of Bovine larvae (Theileria annulata). The clinical manifestations are severe symptoms such as high fever and anemia. If the diagnosis and treatment are not timely, the mortality rate is extremely high and the economic loss is huge. In this paper, 30 yak blood samples collected from Tashkurgan County were tested by PCR for the detection of Theileria annulata. The results showed that the overall positive rate of PCR was 13.3% (4/30), the positive rate of female yak was 13.0%, and the positive rate of male yak was 14.0%. The variance of the disease was found to be insignificant between the sex of yak (P = 0.935 > 0.05), indicating that the plateau yak in the county is infected with Theileria annulata to varying degrees, which is potentially harmful and should be strengthened.
