Quinolone resistance and biofilm formation capability of uropathogenic Escherichia coli isolates from an Iranian inpatients' population.

Our results showed considerable fluoroquinolone and quinolone resistance among UPEC along with a remarkable rate of biofilm-producing isolates from symptomatic hospitalized patients, making them a serious health concern in the region. This survey highlights the need for awareness on quinolone resistance and careful prescription of them by physicians.
