摘要: 为了解猪群中病毒性繁殖障碍疾病的流行状况,用多重PCR诊断方法,对太原市附近14个养猪场和门诊病例共1068份样品进行了猪繁殖与呼吸综合征病毒(PRRSV)、猪瘟病毒(CSFV)、猪细小病毒(PPV)、猪伪狂犬病病毒(PRV)、猪圆环病毒2型(PCV-2)的检测,其平均感染率分别为:PRRSV 32%、CSFV 40%、PPV 20%、PRV 12%、PCV-2 27%。其中混合感染2种病毒的猪群为39%,感染2种病毒的猪为24%。用RT-PCR试剂盒对山西省11个地市66个猪场及121个散养户的1572份血样进行了PRRSV和CSFV的检测,结果PRRSV感染率为33%,CSFV感染率为46%。用间接血凝试验对61个县38个乡136个村179户的1593份血样进行了猪瘟免疫抗体的检测,平均合格率为43.9%,从而为防控此类疫病的发生,制定综合防制措施提供试验数据。

Abstract: In order to investigate the prevalence of porcine reproductive failure caused by viruses, 1068 patient samples from 14 pig farms in the vicinity of Taiyuan were detected using multiplex PCR diagnostic methods. The average infection, rate of porcine reproductive and respiratory syndrome virus (PRRSV), classical swine fever virus (CSFV), porcine parvovirus (PPV), pseudorabies virus(PRV) and porcine circovirus type 2 (PCV-2) were 32%,40%,20%,12%,27%, respectively.More than two viruses mixed infection was 39%,two virus infection was 24%. 1572 blood samples were detected using RT-PCR kits for PRRSV RNA and CSFV RNA in 11 cities of Shanxi province from 66 pig farms and 121 free-range pig farm households. The results showed that PRRSV infection rate was 33%. CSFV infection rate was 46%.1593 blood samples were detected to indentify immune antibody titer of CSFV, the average qualified rate was 43.9%. It provides experimental data for working out comprehensive measures to prevent and control the epidemic diseases.
