[目的]系统了解新疆绵羊群体中绵羊附红细胞体的感染、流行情况.[方法]实验采用鲜血压片、血涂片染色镜检和PCR方法,检测新疆7个绵羊主要养殖区绵羊血样850份.[结果]新疆绵羊群体中附红细胞体感染率很高,采用鲜血压片、血涂片染色镜检感染率达到97%,PCR检测感染率为75%;一年四季均有感染,季节性流行不明显;区域之间感染率无明显差异;感染强度多为中、轻度感染,而重度感染有两个小高峰,分别在5月到6月和11月到12月.[结论]新疆绵羊群体中绵羊附红细胞体存在严重感染;季节转换和饲草料结构的变化是本病发生的主要诱因.

[Objective and Method]To learn the infection and epidemic status of eperythrozoon in Xinjiang,blood sheeting, Wright's stained blood smear with lightmicroscope and PCR were used to detect infection of the sheep eperythrozoon in Xinjiang, eight hundred and fifty blood samples were collected.[Result]The result indicated that there is serious infection of the eperythrozoon in Xinjiang; The infection rate reached 97% by use of blood sheeting and Wright's stained blood smear with light microscope.The infection rate reached 75% by PCR;Throughout the year there are occurrence of infections,no obvious seasonal one and no significant difference between the districts.Infection intensity was moderate or slight,but severe infection included two small peaks, respectively, from May to June and from November to December. [Conclusion]Conclusion was drawn that there was a high infection rate of Eperythrozoon in the population of Xinjiang sheep.The main predisposition of occurrence of this disease lies in the seasonal changes and forage conversion.
