摘要
为了解吉林省部分地区羊泰勒虫病的流行情况,试验采用PCR方法对采自吉林省部分地区羊血液样本235份进行羊泰勒虫检测,并对部分阳性样本进行测序分析,建立系统发育树。结果显示,羊泰勒虫阳性率为28.08%,为吕氏泰勒虫单独感染,没有检测到尤氏泰勒虫和绵羊泰勒虫感染。系统发育树分析表明,吉林省吕氏泰勒虫与青海分离株分布于同一分支,亲缘关系最近,与绵羊泰勒虫、尤氏泰勒虫亲缘关系较远。此次调查为吉林省羊泰勒虫病的综合防治提供了理论依据。
In order to study the prevalence of theileria parasites in ovine infections in sheep. A total of 235 peripheral hlood samples of sheep were collected from Jilin and detected by microscopic examination and PCR. The 18S rRNA gene was cloned from part of positive samples and used for phylogenetical analysis. As a resuh, Theileriosis in goats and sheep was positive in 28.08% of the samples. Phylogenetic tree analysis confirmed Theileria spp. was most closely related to Tlwileria luwenshuni Qinghai strains, but more distantly related to Theileria uilenbergi and Theileria ovis. The resuhs provide important information for prevention and control of Pirnplasma of Cattle and Sheep in the region.
