摘要
为调查重庆市规模化猪场2014—2015年猪流行性腹泻（PED）流行病学特征,采集2014年10月至2015年5月18个疑似发生猪流行性腹泻猪场599份血液样品,采用酶联免疫吸附试验（ELISA）方法,分析猪场腹泻病猪中猪流行性腹泻病毒（PEDV）感染情况。结果发现,重庆市规模化猪场PEDV阳性率,在1~5日龄仔猪为92.47%,5~10日龄仔猪为88.41%,10日龄至断奶前仔猪为82.35%;有腹泻症状的怀孕母猪为52.69%。该病在冬春季节高发,呈流行趋势,严重制约了重庆市养猪业的健康发展,在养猪生产中应加强PED的免疫、监测及综合防控工作。
In this study, we analyzed the epidemiological features of porcine epidemic diarrhea virus（PEDV）in large-scale pig farms in Chongqing from 2014 to 2015 with epidemiological investigation methods. We analyzed PEDV epidemic situation in large-scale pig farms diarrhea sick pigs by collecting blood samples from large-scale pig farms from October 2014 to May 2015 using ELISA method. Results show that 1~5 days piglets positive rate of PEDV infection were 92.47%. And that in 5 to 10 days piglets were 88.41% and in 10 days piglets to preweaning piglets were 82.35%. The results also show that positive rate of PEDV infection in pregnant sows presenting with of diarrhea symptoms group was 52.69%. This study indicates that PEDV was widespread, very severe in winter and spring which imposes great threat to healthy development of pig industry in Chongqing. Results of this study suggested that we should strengthen immune and comprehensive prevention for PEDV in pig production. It has become the current important tasks to prevent swine disease in China.
