Influence of fluoroquinolones on expression and function of P fimbriae in uropathogenic Escherichia coli.


P fimbriae are the major adhesins mediating attachment of pyelonephritogenic Escherichia coli to urinary tract tissues, and they therefore constitute a recognized virulence factor. In this work, the effect of fluoroquinolones on P fimbria expression and function in E. coli SS142 and C1212 was assessed. Ciprofloxacin, fleroxacin, and norfloxacin were… (More)
