Divergent Regulation of Virulence Factors by FimK in Classical and Hypervirulent Klebsiella pneumoniae Pathotypes.
Klebsiella pneumoniae is an opportunistic bacterial pathogen that is increasingly recognized as a major global threat. Type 1 pili, encoded by the fim operon, are virulence factors imperative in K. pneumoniae urinary tract infection. FimK, a regulatory protein, has been shown to repress type 1 fimbrial expression in sp...
