摘　　要：目的了解河北省不同地区猪脑心肌炎病毒(EMCV)感染的流行情况。方法于2006-2008年间从河北省10个地区的31个猪场共采集了1 306份血清,应用间接酶联免疫吸附试验(ELISA)检测血清中EMCV非结构蛋白2C特异性抗体,分析不同地区、不同生长阶段猪群的EMCV抗体阳性率。结果1 306份血清中176份为EMCV 2C抗体阳性,总阳性率为13.48%;监测的10个地区中6个为抗体阳性,阳性率最高为26%;种母猪的EMCV感染率明显高于其他生长阶段猪感染率。结论河北省多个地区的猪场已经有EMCV感染存在,带毒母猪是猪群EMCV感染和流行的主要原因之一。In order to survey the prevalence of encephalomyocarditis virus（EMCV） infection in pigs in Hebei Province from 2006 to 2008,a total of 1306 swine serum from 31 farms in 10 regions in Hebei were tested for antibodies against EMCV nonstructural protein 2C by ELISA.Positive rates of antibodies in different regions and different age groups were analyzed.The results showed that antibodies against EMCV 2C were found in 176 out of 1306 serum samples collected from Hebei Province and the total positive rate was 13.48%.Seroprevalence of EMCV infection appeared in six out of ten surveyed regions and the highest positive rate was 26%.There was significant difference of seroprevalence in EMCV infection between breeder sows and other swine species.This survey indicated that EMCV infection has occurred in pig farms in most regions of Hebei Province and EMCV-carried breeder sows were one of the crucial causes for EMCV infection and prevalence.
