Significance of genomic DNA group delineation in comparative studies of antimicrobial susceptibility of Acinetobacter spp.

There were significant differences in antimicrobial susceptibilities in isolates of genomic DNA groups 2 (Acinetobacter baumannii), 3, and 13TU collected from the same sources, e.g., patients in intensive care units and general wards, and in isolates of the same group collected from different sources. The delineation of genomic groups is important in comparative surveillance studies of antimicrobial susceptibilities.
