摘　　要：[ Objective] To understand the epidemic status of Eperythrozoon ovis in sheep in Xinjiang region of China. [ Method ] A total of 850 blood samples were collected from seven sheep breeding areas in Xinjiang region. The Eperythrozoon ovis infection was detected by blood tablet examination, blood smear stained with Wright＇s stain and polymerase chain reaction （PCR）. [ Result] The infection rates were 97%, 97% and 75% when the samples were detected by blood tablet examination, blood smear stained with Wright＇s stain and PCR, respectively. Sheep eperythrozooo nosis occurred in the four seasons without seasonal epidemics. No obvious difference in infection rates was observed between the sheep breeding areas. The Eperythrozoon ovis infection was slight or mild in most cases, but the infection was severe in two periods, that is, from May to June and from November to December. [ Conclusion] The Eperythrozoon ovis infection is popular in sheep in Xinjiang region of China, and the main inducements may be changes in seasons and forage formula.[ Objective] To understand the epidemic status of Eperythrozoon ovis in sheep in Xinjiang region of China.
