| 摘 要： | 为了了解河北省屠宰场猪只高致病性猪蓝耳病的带毒情况,采用RT-PCR方法对2006～2009年采自全省11个地市228个县级屠宰场1565份商品猪的肺脏或肺门淋巴结进行高致病性猪繁殖与呼吸综合征病毒(HP-PRRSV)病原学检测,结果4年间猪场的阳性比率分别为55.56％、72.50％、44.62％和28.74％；4年样品阳性检出率分别为28.45％、40.74％、12.01％和7.31％.HP-PRRSV同伪狂犬病病毒(PRV)、圆环病毒2型(PCV-2)和猪瘟病毒(CSFV)混合感染所占的比率为61.66％,多以PCV-2和PRV的二重或三重混合感染为主.总之,HP-PRRSV在河北省猪群中污染面积较大,值得高度重视. |

| Abstract: | To investigate the infection status of highly pathogenic porcine reproductive and respiratory syndrome virus(HP-PRRSV) in pigs from slaughterhouses in Hebei Province,1565 samples of lung or pulmonary lymphonodes were collected from 228 slaughterhouses and examined by RT-PCR.The results showed that the average HP-PRRSV positive rates were 28.45%,40.74%,12.01% and 7.31% from 2006 through 2009,respectively.Co-infection of PRRSV with other pathogens was also detected,which were mainly multiple infection,and the... |
