摘要 用犬肾细胞增殖犬细小病毒,经纯化﹑标化作为包被抗原,建立检测犬细小病毒抗体的间接ELISA方法。结果表明:抗原最佳包被浓度5μg/mL;血清最佳稀释度1:40,反应时间45min;酶标抗体最佳稀释度1:2000,反应时间45min;S/P≥0.240判为阳性,≤0.190判为阴性,介于二者之间为可疑。该抗原不与犬瘟热﹑犬传染性肝炎﹑犬冠状病毒病﹑猫泛白细胞减少症病原阳性血清反应;批内重复试验变异系数小于10%,批间重复试验变异系数小于15%;对20份免疫犬血清进行检测,阳性检出率为85%,明显高于血凝抑制试验(65%),符合率为80%。试验结果表明建立的间接ELISA检测犬细小病毒抗体方法特异、灵敏、可重复性好。
