Abstract

The schizont stage of an unidentified Theileria sp. infective for small ruminants was observed. Intact sheep were infected with adult Haemaphysalis qinghaiensis collected from fields where ovine theileriosis was prevalent. When the infested sheep developed theileriosis, tissue and organ smears were prepared. Theileria schizonts were demonstrated in liver, spleen, lung, kidney, lymph node and peripheral blood. Most of the schizonts were found outside the host cells, which was probably a smear artifact. This study adds our knowledge that lung and kidney can be parasitized by schizonts of Theileria sp.

摘要

观察到一种未鉴定的对小反刍动物有感染性的泰勒虫属原虫的裂殖体阶段。将完整的绵羊用从绵羊泰勒虫病流行地区采集的青海血蜱成虫进行感染。当受感染的绵羊患泰勒虫病时，制备组织和器官涂片。在肝脏、脾脏、肺、肾脏、淋巴结和外周血中发现了泰勒虫裂殖体。大多数裂殖体发现于宿主细胞外，这可能是涂片假象。本研究增加了我们对泰勒虫属原虫裂殖体可寄生于肺和肾脏的认识。
