犬在埃立克体病研究中的作用

Canine Ehrlichia and Ehrlichiosis

随着新病原及病原新的致病性不断被发现 ,埃立克体及埃立克体病已经成为预防医学和兽医学研究热点。在已经发现的 1 1种埃立克体病原中 ,有 5种可以直接感染犬 ,引起不同的犬埃立克体病 ;另外 2种为早先分别从人单核细胞埃立克体病和粒细胞埃立克体病患者中分离的病原 ,在流行区的犬体内也可以分离到。资料表明犬对许多埃立克体都极为敏感 ,犬在埃立克体及埃立克体病研究上占有重要地位。鉴于这是我国近年才发现的新病原 ,许多兽医及研究工作者不认识它 ,文章就相关埃立克体对犬的感染和所致疾病以及在流行病学上的意义进行了综述。

As the new pathogen and the new disease caused by it is recognized,Ehrlichia and ehrlichiosis become the focus of preventive medical science and veterinary medicine in recent years. Eleven species were recognized now; five of them can infect dogs and cause different kinds of canine ehrlichiosis. Two species that caused human monocytic ehrlichiosis and human granulocytic ehrlichiosis respectively had been isolated from dogs that lived in the epidemic area. The research results indicated that dogs are sensitive to many species of Ehrlichia,and very important in the domain of Ehrlichia and ehrlichiosis research. Since it is a new pathogen that was found in our country just a few years ago,many veterinary and research workers didn't know Ehrlichia and ehrlichiosis. Here we discussed the canine Ehrlichiosis and its significance in epidemiology.
