摘　　要：为了解2009年-2014年河南省部分地区犬细小病毒（CPV）病流行病学情况,本研究对2009年3月-2014年12月来河南省6个地区（洛阳市、安阳市、焦作市、三门峡市、新乡市和郑州市）部分宠物医院就诊的19 907个病例进行了调查。结果表明：CPV病的发病率为5.87%（1 169/19 907）;6年时间内CPV病的发病率相对稳定,一年四季均可发生,但春季和秋季发病率最高;CPV主要感染4月龄以内的幼犬;公犬与母犬的发病率无明显差别;中小型犬、纯种犬和未接种疫苗的犬感染比例最高;阳性犬主要是从市场购买的幼龄犬;CPV可以与球虫、犬瘟热病毒（CDV）、犬冠状病毒、钩虫、蛔虫、绦虫、焦虫和线虫混合感染,与球虫的混合感染比例较高,与CDV混合感染比例次之。本研究调查的样品数量和来源较广,在一定程度上代表了CPV病在河南省的实际发病情况,为该病的进一步防制提供了现地调查依据。The aim of this study was to assess the epidemiology of canine parvovirus （CPV） in Henan area during the last 6-year period. A total of 19,907 dog clinical samples were collected from pet hospitals in the cities of Luoyang, Anyang, Jiaozuo, Sanmenxia, Xinxiang and Zhengzhou in Henan between 2009 and 2014, and subjected to detection of CPV infection. The results showed that 1,169 samples （5.87%） were CPV-positive detected by the immunochromatographic strip. While, the annual prevalence of CPV ranged from 4.16% to 8.06%. The prevalence was relatively high in the first 4 months of the year with the highest recorded in the 3rd month. Seasonal prevalence ranged from 4.89% to 7.32% with the highest recorded in spring. The prevalence was relatively high among puppies from the delivering during the first 4 months with the highest recorded in the third month. There was no significant difference in prevalence according to sex. In addition, the CPV-positives were higher among purebred dogs, small and medium-sized dogs, dogs without immunization, and dogs purchased from marketplace. Moreover, some of the CPV- positive dogs were also co-infected with coccidium, canine distemper virus （CDV）, hookworm, canine coronavirus, roundworm, tapeworm, and Babesia spp. The co-infection rates of CPV with coceidium were the highest, followed by CDV. Our findings are expected to facilitate a better understanding of the current status of CPV infection among dogs in Henan area.
