河南省部分地区规模化猪场繁殖障碍性疫病的血清学调查

Serological Investigation of Swine Reproductive Failure Diseases in Some Large-scale Pig Farms of Henan Province

[目的]了解河南省部分地区规模化养猪场繁殖障碍性疫病的流行情况,为有目的、有重点地开展相应的猪繁殖障碍性疫病免疫预防工作提供参考。[方法]对河南部分猪场送检于河南农业大学动物疫病检测诊断中心的血清进行监测,其中6 825、2 609、1 177、123和53份血清分别用于检测猪瘟、猪繁殖与呼吸综合征、猪伪狂犬病、猪细小病毒病和衣原体病抗体。[结果]血清学监测结果显示,血清中猪瘟、猪繁殖与呼吸综合征、猪伪狂犬病、猪细小病毒病和衣原体病相应抗体阳性率分别为63.28%、61.44%、25.49%、39.84%、5.66%。[结论]河南省部分地区猪瘟、猪繁殖与呼吸综合征、猪细小病毒病的防疫工作亟待加强,猪伪狂犬病的防治需要进一步强化,衣原体病已得到有效控制。

[Objective]To investigate the prevalence situation of swine reproductive failure diseases in some areas of Henan Province and provide reference for the immunization and prevention of swine reproductive failure diseases.[Method]Between May 2009 and April 2010,all serum samples from the Henan Agriculture University,Animal Disease Detection and Diagnosis Center were detected,including 6 825 serum samples for detecting classical swine fever（CSF） antibody,2 609 for porcine reproductive and respiratory syndrome（PRRS） antibody,1 177 for pseudorabies rabies virus gE（PRV） antibody,123 for porcine parvovirus（PPV） antibody and 53 for chlamydiosis antibody.[Result]The antibody positive rates of serums for detecting above five diseases were respectively 63.28%,61.44%,25.49%,39.84% and 5.66%.[Conclusion]The immunization and prevention of CSF,PRRS,PPV and PR in Henan Province needs to be strengthened urgently,and the chlamydiosis has been effectively controlled.
