    摘要:

    为探明2016年广西猪群主要疫病的感染情况,从发病猪场和屠宰场共采集猪组织样品340份,应用RT-PCR方法检测猪瘟病毒(CSFV)?猪繁殖与呼吸综合征病毒(PRRSV)、猪流行性腹泻病毒(PEDV),应用PCR方法检测猪圆环病毒2型(PCV2)和猪伪狂犬病病毒(PRV)?结果显示,发病猪场中的CSFV、PRRSV、PEDV、PCV2和PRV感染率分别为1.97%?16.45%?0.00%?34.21%和3.95%,而屠宰场猪的感染率分别为0.53%?11.17%?0.00%?43.09%和0.00%?对猪群的混合感染情况进行分析发现,PCV2和其它病原的混合感染率最高?其中,发病猪场二重感染率最高的为“CSFV+PCV2”,为3.95%;其次为“PRRSV+PCV2”,为3.29%?屠宰场二重感染率最高的是“PRRSV+PCV2”,为2.66%?结果表明:临床健康屠宰猪群和发病猪群中的PCV2和PRRSV感染率较高,其中PCV2感染率最高,且常与CSFV和PRRSV发生混合感染;PRV和CSFV主要在发病猪中被检出;加强PCV2和PRV的监控,对控制猪群发病具有重要意义;应通过加强生物安全措施来净化PRRSV和PRV?

    Abstract:

    To understand the current status of normal swine diseases in Guangxi,340 swine tissue samples were collected from clinically morbidity farms and slaughterhouses. CSFV,PRRSV and PEDV were detected by RT-PCR,and PCV2 and PRV were detected by PCR. The results showed that the infection rates of CSFV,PRRSV,PEDV,PCV2 and PRV in morbidity farms were 1.97%,16.45%,0.00%,34.21% and 3.95%,respectively,and these rates in the slaughterhouses were 0.53%,11.17%,0.00%,43.09% and 0.00%,respectively. The mixed infection situation of swine was analyzed,and it was found that the rate of PCV2 coinfection with other virus was the highest. In the morbidity farms,the highest rate of double infection was “CSFV+PCV2”,which was 3.95%,the second was “PRRSV+PCV2”,which was 3.29%. The highest rate of double infection in slaughterhouses was “PRRSV+PCV2”,which was 2.66%. The results indicated that the infection rates of PCV2 and PRSSV were higher,not only in morbidity farms,but also in slaughterhouses. Among them,the infection rate of PCV2 was the highest,and PCV2 coinfection with CSFV and PRRSV was universal. PRV and CSFV were detected mainly in diseased swine. It was important to enhance the surveillance of PCV2 and PRV for the control of swine disease incidence. PRRSV and PRV should be eliminated by strengthening biosafety measures.
