【摘要】：为了解安徽地区不同规模猪场猪伪狂犬野毒(PRV-gE)的感染情况,为防控猪伪狂犬病(PR)提供科学依据,本调查应用ELISA方法,对2012年8月~2015年12月来自224个不同规模猪场的11 855份血清样品进行PRV-gE抗体检测。结果显示,血清样品总阳性率为14.03%,2012年8月~2015年12月分别为2.76%、5.12%、11.61%、26.61%;育肥猪、哺乳仔猪、母猪、保育猪、后备母猪及公猪依次为31.02%、29.27%、27.46%、22.29%、22.22%、18.52%,皖北、皖南和江淮地区分别为28.59%、9.59%、6.49%。猪场总阳性率为41.96%,大型规模场、中等规模场、小型规模场及散养户分别为4.74%、17.00%、23.15%,皖北、皖南和江淮地区分别为48.48%、35.71%、38.53%。结果表明,安徽地区猪群中PRV感染逐年上升,皖北地区样品阳性率显著高于其他地区,其中小型规模场及散养户的感染尤为严重,育肥猪和种猪带毒是伪狂犬病持续存在的重要原因,养殖方式、疫苗免疫、生物安全等因素均对PR的流行产生影响。
[Abstract]:In order to understand the infection of PRV-gE in pig pseudorabies in different size pig farms in Anhui, and to provide scientific basis for the prevention and control of PRV in pig pseudorabies, ELISA method was used in this investigation.From August 2012 to December 2015, 11,855 serum samples from 224 pig farms of different sizes were tested for PRV-gE antibodies.The results showed that the total positive rate of serum samples was 14.03, and 2.76 from August 2012 to December 2015 was 5.12, 11.61 and 26.61, respectively, and that of fattening pigs, lactation piglets, sows, nursery pigs, reserve sows and boars was 22.2922.222.222.222.22 and 18.52in turn, and 28.599.596.49m in northern Anhui, southern Anhui and Jianghuai areas, respectively.The total positive rate of pig farm was 41.96. The total positive rate of large scale field, medium scale field, small scale field and individual family was 4.74 and 17.00 respectively. The total positive rate in northern Anhui, southern Anhui and Jianghuai areas was 48.48 and 35.71 respectively.The results showed that the infection rate of PRV in pig herd in Anhui increased year by year, and the positive rate of PRV was significantly higher in the north of Anhui than in other areas, especially in the small scale field and the individual family.Fattening pigs and breeding pigs with virus are the important reasons for the persistence of pseudorabies. Breeding methods, vaccine immunization, biological safety and other factors have an impact on the prevalence of PR.
