Flowchart of the process of Acb complex inclusion and strain selection for further molecular evaluation. Inclusion criteria was isolation of the Acb complex from non-redundant clinical samples (one per infected patient) obtained during the routine laboratory work. Acb complex - Acinetobacter calcoaceticus–baumannii complex; A. baumannii - Acinetobacter baumannii; BMD - Broth microdilution; CRAB - Carbapenem-resistant A. baumannii; DD - Disk diffusion; MLST - Multilocus sequence typing; PFGE - Pulsed-field gel electrophoresis
