【摘要】：【目的】全面了解广西猪伪狂犬病毒(PRV)的流行特点,为相关部门制定科学的猪伪狂犬病防控措施提供决策参考。【方法】于2013年6月~2016年8月从广西12个地市不同规模猪场采集疑似猪伪狂犬病阳性组织样品473份和血清样品5041份,通过PCR和ELISA分别对组织样品和血清样品进行PRV病原和野毒抗体检测。【结果】广西地区规模猪场的组织样品和血清样品PRV阳性率分别为26.43%和24.50%,且组织样品PRV病原阳性率与血清样品野毒抗体阳性率基本一致,以2015年的PRV阳性率最低、2016年的PRV阳性率最高。在广西地区一年四季均能检测到PRV,且组织样品的PRV病原阳性率和血清样品的野毒抗体阳性率均以第三季度(秋季)最低,分别为19.80%和14.95%。除了梧州市和防城港市的检测样品未检出PRV外,其他10个地市的检测样品均能检出PRV,说明广西规模猪场普遍存在PRV感染,且以南宁、玉林、北海和桂林等地市较严重。【结论】广西规模猪场普遍存在PRV感染,尤其是2016年PRV阳性率明显上升。因此,要求养猪业发达的地市应加大对PRV的防控力度,实时监控PRV的流行趋势,避免混合感染,并做好净化工作。
[Abstract]:[objective] to understand the epidemic characteristics of porcine pseudorabies virus (PRV) in Guangxi. [methods] from June 2013 to August 2016, 473 samples of suspected pig pseudorabies positive tissues and 5041 serum samples were collected from different size pig farms in 12 cities of Guangxi. The positive rates of PRV in tissue samples and serum samples were 26.43% and 24.50% in pig farms in Guangxi, respectively, and the pathogenicity of PRV in tissue samples were 24.50% and 26.43% respectively, and the positive rates of PRV in tissue samples were 26.43% and 24.50% respectively, and the positive rates of PRV in tissue samples were 26.43% and 24.50%, respectively. The positive rate was basically the same as the positive rate of wild virus antibody in serum samples. The PRV positive rate was the lowest in 2015 and the highest in 2016. PRV was detected in all seasons of the year in Guangxi, and the positive rate of PRV in tissue samples and serum samples were the lowest in the third quarter (autumn), which were 19.80% and 14.95%, respectively. With the exception of the samples from Wuzhou and Fangchenggang, PRV could be detected in all the other 10 cities, indicating that PRV infection is widespread in large-scale pig farms in Guangxi, and in Nanning and Yulin. [conclusion] PRV infection is prevalent in large scale pig farms in Guangxi, especially the positive rate of PRV in 2016. Therefore, the prefectures with developed pig industry should strengthen the prevention and control of PRV, monitor the epidemic trend of PRV in real time, avoid mixed infection, and do a good job of purification.
