Prevalence of the crpP gene conferring decreased ciprofloxacin susceptibility in enterobacterial clinical isolates from Mexican hospitals

Abstract

These findings indicate the presence of crpP genes among ESBL-producing isolates from Mexican hospitals and point to widespread crpP-type genes in old Enterobacteriaceae clinical isolates (from 1994). CrpP probably confers resistance by means of the phosphorylation of ciprofloxacin.
