Occurrence of canine parvovirus in dogs from Henan province of China in 2009–2014

Background There is no information concerning the genotype of Canine parvovirus (CPV) currently circulating in Henan province, China. Therefore, the aim of the present study was to provide insights into the epidemiology and molecular characterization of CPV circulating in Henan province from 2009 to 2014. Results Nineteen thousand nine hundred seven dogs from pet hospitals in the cities of Luoyang, Anyang, Jiaozuo, Sanmenxia, Xinxiang, Zhengzhou in Henan province between 2009 and 2014 were investigated. Over the 6-year period, 1169 CPV-positive cases were identified and the morbidity of CPV infection ranged from 4.16 to 8.06 %, although morbidity was not significant (P > 0.05) between 2009 and 2014. Factors associated with morbidity included sampling season, dog age, breed, vaccination status, and sex. CPV co-infection with coccidium (10.00 %), canine distemper virus (4.79 %), hookworm (2.40 %), canine coronavirus (1.11 %), roundworm (1.03 %), tapeworm (0.17 %) and Babesia spp. (0.09...

背景：目前尚无关于中国河南省当前流行的犬细小病毒（Canine parvovirus, CPV）基因型的相关研究资料。因此本研究旨在深入解析2009年至2014年间河南省流行的犬细小病毒的流行病学特征与分子生物学特性。
结果：本研究于2009年至2014年间，对河南省洛阳、安阳、焦作、三门峡、新乡、郑州各宠物医院收治的19907只犬开展了流行病学调查。6年监测期间共检出1169例犬细小病毒阳性病例，犬细小病毒感染发病率介于4.16%至8.06%之间，且2009年至2014年间发病率无显著统计学差异（P＞0.05）。与发病率相关的影响因素包括采样季节、犬只年龄、品种、疫苗接种状态及性别。犬细小病毒混合感染病例中，球虫（coccidium）感染占比10.00%、犬瘟热病毒（canine distemper virus）感染占比4.79%、钩虫（hookworm）感染占比2.40%、犬冠状病毒（canine coronavirus）感染占比1.11%、蛔虫（roundworm）感染占比1.03%、绦虫（tapeworm）感染占比0.17%，巴贝斯虫属（Babesia spp.）感染占比0.09……
