摘  要：
为分析贵州地区2013年~2015年仔猪病毒性腹泻发病情况和流行特征,本研究对2013年~2015年贵州省5个不同的地州(市)采集的27个规模养猪场7 153头猪进行发病时间、发病日龄、发病率、死亡率等发病状况调查,并采用RT-PCR方法对采集的203份仔猪腹泻粪便样品进行病原核酸检测。结果显示,猪群多在冬春季节发生腹泻,发病日龄为2日龄~7日龄,猪群腹泻发病率为61.07%,病死率为71.50%;病原核酸检测结果显示:猪流行性腹泻病毒(PEDV)的阳性率为63.54%,猪传染性胃肠炎病毒(TGEV)的阳性率为0.98%,猪轮状病毒(Po RV)的阳性率为7.88%;PEDV与TGEV混合感染率为0.99%,与Po RV混合感染率为10.84%。该调查结果表明贵州地区仔猪病毒性腹泻发病率及病死率均较高,引起仔猪病毒性腹泻的主要病原为PEDV,并且出现PEDV/TGEV和PEDV/Po RV的混合感染。

摘  要：
In order to investigate epidemic characteristics of viral diarrhea in piglets during 2013 to 2015 in Guizhou region, a total of 7,135 pigs were surveyed on the prevalence of the viral diarrhea diseases by RT-PCR detections in 27 large-large scale pig farms of five different places in Guizhou area during this period. The results display that the newborn piglets were more likely to be infected at 2 to 7 days post-delivery with higher morbidity in spring and winter, and the diarrhea rate of pigs was 61.07% with a mortality of 71.50%. The RT-PCR detection results showed that the positive rates were 63.54% for porcine epidemic diarrhea virus(PEDV), 7.88% for porcine rotavirus(Po RV) and 0.98% for transmissible gastroenteritis virus(TGEV), respectively. The mixed infection rates were 10.84% for PEDV with Po RV and 0.99% for PEDV with TGEV. These data indicated that the viral diarrhea caused a relatively high morbidity and mortality in the piglets in Guizhou area and the main pathogen is PEDV, together with the mixed infection of Po RV and TGEV.
