Results from the study showed that: There was the relationship between minimum inhibitory concentrations (MIC) of carbapenem (≥ 8 µg / ml) with the presence of carbapenemase (through phenotypic test: Carbapenem Inactivation Method - CIM, CarbaAcineto NP and modified CarbaAcineto NP) and carbapenemase encoding genes (blaOXA-23-like, blaNDM-1) among A baumannii strains.
