Monoclonal antibodies (MAbs) against seven serologically different P fimbriae (F7(1), F7(2), F8, F9, F11, F12, and F13) of uropathogenic Escherichia coli were tested for their ability to detect the P fimbriae on wild-type strains. In a plate agglutination test the MABs could detect the fimbriae on strains which expressed cloned fimbriae but not on wild-type strains. In a coagglutination test and in a whole-bacterium enzyme-linked immunosorbent assay the MAbs recognized the fimbriae on strains with cloned fimbriae and on wild-type strains. However, the coagglutination test has some disadvantages: only immunoglobulin G MAbs can be used, and the results cannot be read in an objective way. From these results, we concluded that the whole-bacterium enzyme-linked immunosorbent assay is the most convenient method for the determination of P fimbriae on wild-type E. coli strains. With this fast and easy method it is possible to do epidemiological studies on the distribution of P fimbriae among clinical isolates of uropathogenic E. coli and to extend the O:K:H serotype with the F serotype.
检测了针对尿路致病性大肠杆菌七种血清学不同的P菌毛(F7(1)、F7(2)、F8、F9、F11、F12和F13)的单克隆抗体(MAb)检测野生型菌株上P菌毛的能力。在平板凝集试验中,单克隆抗体能够检测出表达克隆菌毛的菌株上的菌毛,但不能检测野生型菌株上的菌毛。在协同凝集试验和全菌酶联免疫吸附试验中,单克隆抗体能够识别表达克隆菌毛的菌株和野生型菌株上的菌毛。然而,协同凝集试验有一些缺点:只能使用免疫球蛋白G单克隆抗体,并且结果无法客观读取。从这些结果中,我们得出结论,全菌酶联免疫吸附试验是测定野生型大肠杆菌菌株上P菌毛最方便的方法。通过这种快速简便的方法,可以对尿路致病性大肠杆菌临床分离株中P菌毛的分布进行流行病学研究,并将O:K:H血清型扩展为F血清型。
