摘要: 为了解江西省猪群猪传染性胸膜肺炎放线杆菌(APP)感染现状,本试验利用APP江西分离株研制了抗体间接血凝检测法(IHA)。试验将纯化的APP江西分离株培养菌液反复冻融,经超声波裂解处理后提取菌体抗原,致敏经戊二醛固定鞣酸化的兔红细胞,成功建立了APP抗体的IHA法。应用该法对猪瘟病毒、猪繁殖与呼吸综合征病毒、猪伪狂犬病病毒等病毒的阳性血清进行检测试验,结果均为阴性;对大肠杆菌、沙门氏菌、副猪嗜血杆菌阳性血清检测均为阴性。不同批次APP抗原经IHA检测,结果显示重复性好。本试验结果表明所建立的APP抗体IHA检测法有较好的特异性和重复性,为下一步血清学调查奠定基础。

Abstract: In order to understand the infection status of Actinobacillus pleuropneumoniae in Jiangxi province, we developed indirect hemagglutination assay (IHA) for detection of antibody by using APP isolates of Jiangxi province. IHA consisting of glutaraldehyde-tannic-fixed rabbit red blood cells (RRBC) coated with the supernatant of repetitive freeze-thawed and sonicated APP was established. The positive sera of hog cholera virus, porcine reproductive and respiratory syndrome virus, pseudorabies virus, Escherichia coli, Salmonella, Haemophilus parasuis showed negative results. Different batches of IHA antigen showed good repeatability. The results showed that the specificity and repeatability of IHA were good, which created the foundations for the serological survey.
