【摘要】：为初步了解我国上海市及周边部分地区猪传染性胸膜肺炎放线杆菌(Actinobacillus pleuropneumoiae,APP)的感染情况,对2015~2016年间采集于上海市、江苏省、江西省以及浙江省部分地区的1031份猪血清进行胸膜肺炎放线杆菌感染情况检测。结果显示,上海市及周边地区部分规模化猪场猪群中APP抗体总阳性率为27.06%,其中APP抗体阳性率江西省(38.08%)、江苏省(33.09%)和浙江省(25.21%)均高于上海市(11.20%);种猪(37.74%)高于哺乳仔猪(33.16%)和育肥猪(25.96%)以及保育猪(14.68%);APP抗体水平夏季(40.25%)高于冬季(25.00%)、春季(28.21%)和秋季(15.29%);小型猪场(42.11%)高于中型(24.86%)和大型猪场(17.97%)中APP抗体阳性率。统计分析显示,APP抗体阴、阳性与地区、猪群的生长阶段、生长季节以及猪场规模有关(P0.001)。检测结果表明,我国上海市及周边地区猪群中胸膜肺炎放线杆菌感染较为普遍。本研究结果为我国猪传染性胸膜肺炎(porcine contagious pleuropneumonia,PCP)的防控以及净化工作提供了一定的数据支持。
[Abstract]:In order to understand the infection status of Actinobacillus pleuropneumoaeae APP in Shanghai and its surrounding areas, the samples were collected in Shanghai, Jiangsu Province from 2015 to 2016. In Jiangxi Province and some parts of Zhejiang Province, 1 031 pig serum samples were tested for Actinobacillus pleuropneumoniae infection. The total positive rate of APP antibody in some large-scale pig farms in Shanghai and its surrounding areas was 27.06, of which the positive rate of APP antibody in Jiangxi Province (38.08g), Jiangsu Province (33.099) and Zhejiang Province (25.21) was higher than that in Shanghai (11.20%); breeding pig (37.74)) was higher than that in breast-feeding piglets (33.16) and fattening pigs (25.96%).). The antibody level of app in summer was higher than that in winter (28.21 in spring) and in autumn (42.11) was higher than that in medium scale (24.86) and in large pig farm (17.97). The positive results were related to the growth stage, growing season and the size of pig farm. Actinobacillus pleuropneumoniae infection is common in pigs in Shanghai and its surrounding areas. The results of this study provide some data support for the prevention, control and purification of porcine contagious pleuropneumoniae in China.
