ERIC2 PCR patterns of TMP–SMZ-resistant, clonal group A (CgA) and ciprofloxacin-TMP–SMZ-resistant E. coli UTI isolates. Lanes 1 and 12, 1 kb ladder; lane 2, CgA prototype isolate and positive control; lanes 3–6, putative CgA isolates; lanes 7–11, ciprofloxacin-TMP–SMZ-resistant isolates, including CgG (lanes 7–9); lane 13, negative control. All isolates were recovered from unique women, except 1792 (lane 4) and 2000 (lane 5), which were isolated from two UTI episodes in the same woman, 57 days apart.
