The prevalence of 31 virulence factors was analyzed among nalidixic acid-susceptible and -resistant Escherichia coli strains from phylogenetic group B2. Hemolysin, cytotoxic necrotizing factor 1, and S and F1C fimbriae genes were less prevalent among nalidixic acid-resistant E. coli strains. Quinolone resistance may be associated with a decrease in the presence of some virulence factors.
对来自系统发育B2组的耐萘啶酸和萘啶酸敏感的大肠杆菌菌株中的31种毒力因子的流行情况进行了分析。溶血素、细胞毒性坏死因子1以及S和F1C菌毛基因在耐萘啶酸的大肠杆菌菌株中不太常见。喹诺酮耐药性可能与某些毒力因子的存在减少有关。
