OPRD1 and bathing suit ichthyosis: Next, 7 FQ/meropenem-non-susceptible, oprD-mutant BSI isolates from OHSU HM/HCT patients (ST111/M0067, ST111/M0101, ST111/218M0087, ST111/M0025, ST291/M0103, ST299/M0128, and ST446/M0117, see Table 2) were evaluated to determine whether the colonization advantage seen in oprD transposon mutants was also observed in the clinical isolates.
