Abstract: The present study was conducted to investigate tick species and tick-transmitted Theileria and Babesia species in Qinghai Province, Northwestern China. A total of 357 ticks, belonging to 2 Ixodid genera, Haemaphysalis qinghaiensis (167; 46.8%) and Dermacentor nuttalli (190; 53.2%) were collected from the domestic animals during May and June 2010. The ticks were separated into 78 tick pools according to their species and examined for Theileria and Babesia species by a nested PCR targeting 18S rRNA gene. Of the 25 H. qinghaiensis pools, 2 (8.0%) were tested positive for Theileria. Only 1 (1.9%) was tested positive for Babesia in 53 D. nuttalli pools. The sequence and phylogenetic analyses showed that Babesia and Theileria detected in this study were grouped into B. caballi and T. luwenshuni, respectively implying the potential existence of theileriosis and babesiosis in animals in Qinghai Province.
