中文摘要:
      为评估常见猪病原的隐性感染情况,使用荧光PCR检测技术对采自13个屠宰场的1 224份健康猪淋巴结、1 194份健康猪扁桃体进行高致病性猪繁殖与呼吸综合征病毒(HPPRRSV)、猪繁殖与呼吸综合征病毒(PRRSV)、猪瘟病毒(CSFV)、猪伪狂犬病毒(PRV)等主要猪病病原进行核酸检测。结果显示,屠宰场内健康猪群中的病原阳性率分别为PRV 7.5%、PRRSV 4.5%、HPPRRSV 1.4%、CSFV 0.2%,表明健康猪群中有部分猪携带有致病性病原。
英文摘要:
      In order to evaluate the silent infection of the main pathogens in pigs,1 224 lymph nodes and 1 194 tonsils were collected from 13 pig slaughterhouses to detect porcine reproductive and respiratory syndrome virus (PRRSV),high pathogenic porcine reproductive and respiratory syndrome virus(HPPRRSV),classical swine fever virus(CSFV)and pseudorabies virus(PRV)by using fluorescent PCR technology. The results showed that the PRV infection rate in healthy swine herds was the highest,up to 7.5%,and the following was PPRSV( 4.5%),HPPRRSV (1.7%),CSFV (0.2%). The results indicated that some pigs in clinical healthy swine herds carryed pathogenic pathogens.
