摘要:

运用ELISA、LAT和IHA对湖北省2006年度规模化猪场猪伪狂犬病(PR)、猪繁殖与呼吸综合征(PRRS)、猪乙型脑炎(JE)、猪细小病毒病(PP)、猪瘟(HC)、猪圆环病毒病(PCV-2)及弓形体病进行了血清学检测。分析调查结果发现PR、PRRS、JE、PP 、HC 5种疾病的免疫抗体平均阳性率分别为84.3%、78.3%、84.7%、58.0%、79.7%。非免PRRSV和PRV野毒的平均感染率分别为55.1%和17.7%,表明PRRSV感染情况比较严重。对58场次发病猪场的541份血清进行PRV、PRRSV、PCV-2混合感染情况的调查发现,规模化猪场中普遍存在二重或三重感染,从而使疾病更加复杂化,给防疫工作带来更大的困难。

Abstract: The porcine sera from intensive concentrated farms were examined by ELISA、LAT and IHA using the antibodies against seven diseases in 2006, including pseudorabies virus(PRV),porcine reproductive and respiratory syndrome virus(PRRSV),japanese encephalitis virus(JEV),porcine parvovirus(PPV),hog cholera virus(HCV),porcine circovirus(PCV) and Toxoplasmosis. Analysis results indicated that average positive rate of immunity antibody of HC,PR,PRRS,JE,PP were 84.3%,78.3%,84.7%,58.0%,79.7%, separately. The PRRSV infected seriously with the unvaccined pigs' average infective rate of PRRSV was 55.1%, but average infective rate of wildtype PRV was only 17.7%. Coinfectons among PRV,PRRSV and PCV-2 were detected by the 541 serum samples from the 58 infected farms. The results showed that double or triple coinfections were very genenral, which made diseases more complicated and preventions more difficult.
