目的:建立一种快速诊断布鲁氏菌感染的方法。方法:将布鲁氏菌可溶性菌体抗原结合于硝酸纤维膜上,以胶体金颗粒结合的羊抗人IgG作为标记抗体,建立滴金免疫测定法,检测布鲁氏菌感染者血清抗体,通过布鲁氏菌抗原抗体渗滤在硝酸纤维膜上反应...目的:建立一种快速诊断布鲁氏菌感染的方法。方法:将布鲁氏菌可溶性菌体抗原结合于硝酸纤维膜上,以胶体金颗粒结合的羊抗人IgG作为标记抗体,建立滴金免疫测定法,检测布鲁氏菌感染者血清抗体,通过布鲁氏菌抗原抗体渗滤在硝酸纤维膜上反应,2 m in后肉眼观察结果。并与试管凝集试验比较。结果:滴金免疫测定法的敏感性为95.35%(41/43),特异性为98.99%(98/99),其他病患者血清反应均为阴性,Youden′s指数为0.9434。滴金免疫测定法与试管凝集试验的符合率为97.89%(139/142),两法无显著性差异(P>0.05)。结论:滴金免疫测定法可用于布鲁氏菌病的临床检测和流行病学筛查,具有推广应用价值。展开更多
