2009-2010年云南部分猪场猪主要传染病血清流行病调查

Blood Serum Epidemic Research of Major Porcine Infectious Disease of Partial Hogpen from 2009 to 2010 in Yunnan Province

为了探查2009-2010年云南部分猪场对猪主要传染病疫苗接种后的免疫效果,本试验主要通过ELISA方法对样品进行血清流行病调查。结果表明,猪瘟病毒(classical swine fever virus,CSFV)抗体阳性率为84.33%(1211/1436);猪繁殖与呼吸综合征病毒(porcine reproductive and respiratory syndrome virus,PRRSV)抗体阳性率为74.84%(803/1073);猪圆环病毒2型(porcine circovirus type 2,PCV2)抗体阳性率为0.00%(0/80);猪伪狂犬病病毒(pseudorabies virus,PRV)抗体阳性率为62.26%(287/461);猪细小病毒(porcine parvovirus,PPV)抗体阳性率为54.25%(83/153);日本乙型脑炎抗体阳性率为63.33%(76/120)。提高PRRSV、PRV、PPV和乙脑疫苗的使用效果是云南省内猪场解决母猪流产的有效途径。

Blood serum epidemic research which to find the immune effect of partial hogpen from 2009 to 2010 in Yunnan province after major porcine infectious disease vaccine injection had been taken by ELISA test and latex agglutination test.The result showed the positive rate of porcine antibody respectively against CSFV,PRRSV,PCV2,PRV,PPV and Japanese encephalitis virus made up 84.33%（1211/1436）,74.84%（803/1073）,0.00%（0/80）,62.26%（287/461）,54.25%（83/153） and 63.33%（76/120）.After considering all the results presented above,we can safely predict that it＇s high time we prevent and lessen sow aborted by improving PRRSV,PRV,PPV and Japanese encephalitis virus vaccine using effect.
