摘  要:
以纯化的重组F41菌毛蛋白作为检测抗原,建立了检测产肠毒素大肠杆菌F41菌毛抗体的间接ELISA方法。经优化筛选的最佳反应条件:包被抗原浓度为0.26μg/孔,血清稀释度为1∶800,酶标二抗工作浓度为1∶6 000,30 g/L明胶封闭1 h,底物作用时间为10 min。经试验验证,该方法具有特异性好、敏感性高、重复性好、稳定性强等特点。用建立的间接ELISA方法与PCR方法进行符合性试验,总符合率为97.4%。表明,该方法可以用于产肠毒素大肠杆菌F41菌毛抗体的检测。

摘  要:
An indirect enzyme-linked immunosorbent assay(ELISA) was developed based on a purified recombinant F41 pili protein of enterotoxigenic Escherichia coli(ETEC).The optimum test conditions were as follows:the concentration of coating antigen was 0.26 μg per well,the dilution of serum and HRP-labeled mice anti-bovine IgG were 1∶800 and 1∶6 000,respectively,30 g/L gelatin blocked for 1 h,and the reaction time of coloration was 10 min.The specificity,sensitivity,reproducibility and stability were evaluated.Compared with antigen from PCR,97.4% agreement for positive and negative samples were obtained.The results indicated that the indirect ELISA could be used for detecting anti-F41 pili antibodies of ETEC.
