[ Objective ] Piropiasmosis often occurred in the scattered feeding cattie farm in Southern Xinjiang. This disease is a tick - borne endemic biood protozoai disease with high mortaiity rate. This research aimed to investigate the prevaience rate of piropiasmosis and vector tick in some cattie farms better prevent and controi piropiasmosis and reduce the ioss that was caused by this disease to the raisers. [ method ] The author coiiected materiais with iocai veterinarians and owners, took them back to the schooi iaboratory, identified and anaiyzed the vector ticks and pathogen by microscope and the data about piropiasmosis. [ Result ] Bovine tropicai theiieriosis and bovine babesiosis were judged by comprehensive judgment, and the main vector ticks were Hyalomma detritum Hyalomma asiaticum and Boophilus microplus. The infection rate of biood protozoa was 84% : bovine theiieria annuiata 71. 4% ; Babesia bigemina 40. 5% ; babesia bovis 29%. [ Conclusion ] Through this survey we detaiied the occurrence and epidemic status of piropiasmosis in some cattie farms and the predominant distributive species of the iocai vector ticks, and found that there were severai piropiasmosis cross - infection. The resuit provides some scientific basis for the prevention of piropiasmosis.
