Tigecycline is regarded as a last-resort treatment for multidrug-resistant Acinetobacter baumannii. However, tigecycline resistance in A. baumannii has increased worldwide. In this study, we investigated heteroresistance isolates from South Korea. Antibiotic susceptibility testing was performed on 323 nonduplicated isolates. Among 260 and 37 tigecycline-susceptible -intermediate-resistant isola...
Nine Staphylococcus capitis isolates from blood cultures of newborns were examined for resistance to vancomycin. MICs were within the susceptible range, but population profiling revealed a resistant subpopulation. Only isolates with the largest subpopulation were identified as heteroresistant to vancomycin by Etest. This finding may have therapeutic implications.
Characteristic for methicillin-resistant (Mcr) staphylococci is the heterogeneous expression of the intrinsic methicillin resistance. The majority of the cells express resistance to low concentrations of methicillin, and a minority of the cells express resistance to much higher concentrations. We show here (i) that the presence of the mecA encoding region on plasmid pBBB79 was sufficient to ren...
