摘要
[目的]为猪轮状病毒的针对性防治提供建议。[方法]以不同来源、不同饲养方式下218头猪的粪便为材料,用ELISA双抗夹心法检测其中的轮状病毒(RV)抗原,结合流行病学调查对猪轮状病毒的发病因素及发病特点进行分析。[结果]RV多为隐性感染,且感染率较高。从所取218份样品中共检测出RV阳性50头份,阳性率为22.94%,其中,仔猪170头份,阳性率22.35%,中猪48头份,阳性率25.0%;笼养模式下猪的发病率最低,为17.43%,农户圈养方式下猪的发病率最高,达36.84%。[结论]流行病学调查结果显示,仔猪对RV的感染率高于中猪,采取笼养模式,并对仔猪进行RV防治可降低猪RV的发病率。
[Objective] The study was to provide the suggestions for the appropriate prevention on porcine rotavirus. [Method] With stool of 218 pigs from different sources and feeding manners as the materials, the antigen of porcine rotaviras （RV） in them was detected by sandwich ELISA. Combined with epidemiology survey, the pathogenic factors and characters of porcine rotavirus were analyzed. [Result] Most RV were inapparent infection and its infection rate was higher. Total 50 pigs with positive RV were detected from 218 pigs and the positive rate was 22.94%. Among which, there were 170 piglets and their positive rate was 22.35%, while the medium pig was 48 and its positive rate was 25.0%. The pig incidence in captivity was the lowest, being 17.43%, while that in captive was the highest, being 36.84%. [Conclusion] The investigation results of epidemiology indicated that the RV infection rate of piglets was higher than that of medium pig. Taking captivity and prevention RV from piglets could decrease the V infection rate of pig.
