江苏省常州地区犬冠状病毒病的流行病学调查分析

Epidemiological Investigation of Canine Coronavirus Disease in Changzhou,Jiangsu Province

本研究采集常州地区3家宠物医院106例犬粪便和肛拭子,经胶体金和RT-PCR鉴定共检出45例犬冠状病毒(CCV)阳性病例,阳性检出率达到42.45%。对发病月份以及发病月龄进行统计学分析发现,1-3月龄幼犬属于CCV高发群体,阳性检出率可达44.44%;发病月份主要集中在冬春两季(10月~次年3月),发病率合计86.67%。感染犬常表现肠道症状,临床主要可见以腹泻为主。未经接种疫苗或者疫苗接种程序不完全的犬感染CCV概率远高于接种完成的犬。调查结果表明,常州地区宠物犬对犬冠状病毒病的感染率较高,需引起足够的重视。
