摘　　要：为调查重庆市部分规模化猪场2014—2015年猪轮状病毒（PRVs）的血清流行病学特征,2014年10月至2015年5月采集18个疑似发生PRVs感染猪场的599份猪血液样品,采用美国KERNEL PRVs野毒感染抗体ELISA方法,分析猪场腹泻病猪中PRVs感染情况。调查发现;重庆市部分发生腹泻的规模化猪场中,PRVs在1~5日龄仔猪中的阳性率为95.70%,在5~10日龄仔猪中的阳性率为91.30%,在10日龄至断奶前仔猪中的阳性率为86.77%,在怀孕的出现腹泻症状的母猪中的阳性率为73.12%;PRVs感染在冬春季节高发,呈区域性流行。调查结果表明,在发生腹泻的规模化猪场中,PRVs是引发猪腹泻的重要病原之一;在养猪生产中,应加强对PRVs的免疫、监测及综合防控工作。In order to investigate the epidemiological features of porcine rotavirus （PRV） in large-scale pig farms in Chongqing city during 2014--2015, 599 blood samples from 18 suspected PRV infected pig farms were collected to analyze its morbidity situation using ELISA kits of American KERNEL company from October 2014 to May 2015. Results showed that the positive rate of PRV infection in 1-5 days old piglets was 95.70%, and that in 5-10 days old piglets was 91.30%, while that in 10-day-old piglets to weanling piglets was 86.77%. The results also showed that the positive rate in pregnant sows presenting diarrhea symptoms was 73.12%. PRV was regional prevalence and infected with high incidence in winter and spring. This study indicated that PRV was one of the important pathogenic reasons causing diarrhea in large-scale pig farms and the immunization, monitoring, and control for PRV should be strengthened in pig production.
