藏猪传染性胸膜肺炎血清流行病学调查

Seroepidemiological Investigation of Infectious Pleuropneumonia in Tibetan Pigs

为了解藏东地区藏猪胸膜肺炎放线杆菌的感染状况并分析其风险因素,试验从林芝、昌都两市103个藏猪养殖场(户)随机采集588份藏猪血清,应用ELISA法进行血清抗体检测,同时开展风险因素问卷调查,通过SPSS23.0软件进行统计学分析。结果表明:藏东地区猪胸膜肺炎放线杆菌群体阳性率为84.47%(87/103),个体阳性率为46.26%(272/588),其中,昌都市阳性率为70.86%(214/302),林芝市阳性率为20.28%(58/286),不同地区、年龄的藏猪阳性率差异极显著(P<0.01),不同养殖模式、不同性别的藏猪之间,阳性率差异不显著(P>0.05)。研究结果对藏东地区藏猪传染性胸膜肺炎的防控具有指导意义。

In order to understand the infection status of Actinobacillus pleuropneumoniae in Tibetan pigs in eastern Tibet and analyze its risk factors,588 Tibetan pig sera were randomly collected from 103 Tibetan pig farms(households)in Nyinchi and Changdu areas,and then serum antibodies were detected by ELISA,while risk factors were investigated.Statistical analysis was carried out by SPSS 23.0 software.The results showed that the population positive rate of Actinobacillus pleuropneumoniae in eastern Tibet was 84.47%(87/103),and the individual positive rate was 46.26%(272/588).Among them,the positive rate in Changdu was 70.86%(214/302),and that in Nyingchi city was 20.28%(58/286).There were significant differences in the positive rate of Tibetan pigs in different regions and ages(P<0.01).There was no significant difference in the positive rate(P>0.05).The results had guiding significance for the prevention and control of infectious pleuropneumonia of Tibetan pigs in eastern Tibet.
