Fluoroquinolone resistance among CTX-M producing uropathogenic Escherichia coli from HIV and non-HIV patients in South India

Background Extended spectrum b-lactamase (ESBL) especially, the CTX-M producing Escherichia coli has emerged world wide as the leading cause of community onset UTI in the era of antibiotic resistance. The CTX-M producers often exhibit co-resistance towards fluoroquinolones and are a growing challenge to patient care. The purpose of this study was to determine the incidence of fluoroquinolone resistance among CTX-M producing uropathogenic E.coli (UPEC).
