中文摘要：

目的初步了解上海市犬体表蜱虫寄生情况。方法2011年3—12月，在上海市18个区（县）采用动物体表采集法捕获犬体表蜱类样本，将蜱虫样本带回实验室，在解剖显微镜下观察成蜱形态，通过形态学鉴定蜱种类。结果在上海市18个区（县）共调查犬1950只，其中在嘉定、闵行、浦东、松江、黄浦、金山6个区的犬体表共捕获蜱虫328只，经实验室鉴定分为2属2种；宠物犬体表寄生的蜱种为血红扇头蜱和长角血蜱，实验犬和警犬体表寄生的蜱种为血红扇头蜱。结论血红扇头蜱是上海市犬体表寄生的优势蜱种，长角血蜱是新发现的寄生于上海市犬体表的硬蜱蜱种；应加强对媒介蜱的防控。

Objective To investigate the ticks which parasitize on the bodies of dogs in Shanghai. Methods The tick sam-ples were collected from the dogs in 18 districts and counties of Shanghai from March to December in 2011, and the ticks were identified for the species through the morphological analysis by the dissecting microscope in laboratory. Results Totally 1 950 dogs were investigated for ticks parasitizing on the bodies of districts including Jiading, Minhang, Pudong, Songjiang, Huangpu and Jinshan. These ticks were belong to 2 species of 2 genera by morphological analysis in laboratory. Rhipicephalus sanguineus and Haemaphysalis longicornis were the ticks parasitizing on the bodies of pet dogs. R. sanguineus was the main ticks parasitizing on the bodies of police dogs and laboratory dogs. Conclusion R. sanguineus is the domain tick parasitizing on dogs in Shanghai, and H. longicornis is a newly found hard tick species parasitizing on dogs in Shanghai. We should strengthen the prevention and control of ticks.
