Prevalence of ST131 Among Fluoroquinolone-resistant Escherichia coli Obtained From Rectal Swabs Before Transrectal Prostate Biopsy

In our locale, the epidemic multidrug-resistant ST131 clonal group accounts for 70% of FQ-R rectal E coli isolates among men undergoing TPB. Such ST131 isolates have distinctive virulence profiles, are extensively antimicrobial-resistant, and are negatively associated with Asian race. Further investigation is needed regarding risk factors for and clinical consequences of colonization with such strains among men undergoing TPB.
