摘　　要：于2011年8月采用逆毛式检蜱法采集重庆、福建、广东、海南、广西、河北、河南、湖南、山西、江苏和浙江等11个省(市、区)19处警犬基地警犬体表蜱虫,共计399只。采用巢式PCR和序列测定方法,对蜱体内的巴贝虫感染情况进行初步调查。结果显示,警犬体表寄生蜱体内巴贝虫总阳性率为5.3%(21/399),均为佛氏巴贝虫(Babesia canis vogeli)。其中重庆、广东、广西、海南和浙江等5省(市、区)警犬基地采集的蜱虫,巴贝虫阳性率分别为4/16、3.6%(1/28)、12.5%(11/88)、3.3%(4/121)和1/15。提示中国警犬体表寄生的蜱虫,存在一定比例的佛氏巴贝虫感染阳性率,接触人员有潜在感染的风险,应加强预防和控制。399 tick specimens were collected from the body surface of police dogs in Chongqing municipality, provinces of Fujian, Guangdong, Hainan, Guangxi, Hebei, Henan, Shanxi, Jiangsu and Zhejiang. Nested-PCR and se-quence testing were taken to investigate the prevalence of Babesia sp. in ticks. The results showed that Babesia vogeli was found in ticks infested on the body surface of police dogs, with a positive rate of 5.3%. The prevalence in Chongqing, Guangdong, Guangxi, Hainan and Zhejiang was 4/16, 3.6%（1/28）, 12.5%（11/88）, 3.3%（4/121） and 1/15, re-spectively. It suggested that there was a certain rate of infected ticks infested on the body suriface of police dogs, which contrubuted to the potential threat to staff. The prevention and control measures should be strengthened.
