摘  要:为了研究黑龙江省部分地区猪繁殖与呼吸综合征(PRRS)血清学流行情况,采用ELISA方法对采集于72个猪场共计1 237份血清样品(仔猪653份,母猪584份)中的猪繁殖与呼吸系统综合征病毒(PRRSV)抗体进行了检测,并通过调查问卷对猪场感染PRRSV的潜在风险因素进行识别。结果表明:免疫猪群中仔猪PRRSV抗体流行率为61.5%[95%置信区间(CI):58.6,64.4],母猪为81.7%(95%CI:79.3,84.1);未免疫猪群中仔猪PRRSV抗体流行率为52.3%(95%CI:49.8,54.8),母猪为63.6%(95%CI:61.0,66.2);猪群PRRSV抗体流行率为92.9%(95%CI:89.0,96.8)。没有发现与该地区猪场感染PRRSV相关联的风险因素。To study serological prevalence of porcine reproductive and respiratory syndrome (PRRS) in some areas of Heilongjiang province, a total of 1 237 blood samples (653 copies of piglets, 584 copies of sows) collected from 72 pig farms were tested using ELISA for detecting Pro- cine reproductive and respiratory syndrome virus(PRRSV) serum antibodies. A questionnaire was used to identify potential risk factors associated with PRRSV infection in the infected pig farms. The test results showed that the PRRSV antibody prevalence rates in immunized piglets and sows were 61.5% (95% CI : 58.6, 64.4) and 81.7% (95% CI : 79.3,84.1 ) , respectively. In non - immunized herds, the PRRSV antibody prevalence rates in piglets, sows and herds were 52.3% (95% CI: 49.8,54.8), 63.6% (95% CI: 61.0,66.2) and 92.9% (95% CI: 89.0,96.8 ), respectively. No risk factor was found to be associated with the PRRSV infected pig farms.
