2015～2016年我国东北三省地区猪A、B、C群轮状病毒流行情况调查

Epidemiological Survey of Rotavirus A,B and C in Sucking Piglets from Three Provinces of Northeast China during 2015-2016

为了解我国东北三省地区(黑龙江省、辽宁省、吉林省)规模化猪场新生仔猪的猪A群轮状病毒(GARV)、猪B群轮状病毒(GBRV)和猪C群轮状病毒(GCRV)的流行情况。利用巢式PCR方法对2015年1月至2016年10月从我国东北三省地区多个规模化猪场采集的108份仔猪腹泻病料和15份健康仔猪粪便样品进行分析。结果显示:黑龙江省GARV阳性率为47.4%,GBRV未检出,GCRV阳性率为5.3%;辽宁省GARV阳性率为51.5%,GBRV阳性率为3.03%,GCRV阳性率为6.1%;吉林省GARV的阳性率为21.1%,GBRV阳性率为7.1%,GCRV阳性率7.1%;并且存在GARV/GCRV混合感染的情况,因此,我国东北三省地区猪轮状病毒病的主要病原是GARV,但GBRV和GCRV也是幼龄猪群潜在的重要致病风险。为我国猪轮状病毒病的提前预防和综合防控提供流行病学参考数据。

In order to understand the epidemic situation of porcine group A rotavirus (GARV),porcine group B rotavirus(GBRV)and porcine group C rotavirus(GCRV)in three provinces of Northeast China(Heilongjiang,Liaoning,Jilin province).From Jan. 2015 to Oct.2016,108 samples of piglets’ diarrhea disease and 15 samples of healthy piglets’ feces were detected by RT-nPCR.The results showed that the positive rate of GARV was 47.4%,GCRV was 5.3%,the GBRV was not detected in Heilongjiang province.In Liaoning province the positive rate of GARV was 51.5%,GBRV was 3.03%,GCRV was 6.1%.In Jilin province the positive rate of GARV was 21.1%,GBRV was 7.1%,GCRV was 7.1%,and there was a mixed infection of GARV and GCRV.The main pathogens of rotavirus diarrhea in Northeast China was GARV,while GBRV and GCRV were potentially pathogenic in young suckling pigs.It could provide epidemiological data for early prevention and comprehensive prevention and control of swine viral diarrhea in China.
