Figure 4.

The percentage of bacteria of each species that produce certain types of carbapenemases taken under consideration in this study. The presence of KPC, OXA-48, GES, NDM, and VIM were confirmed by the molecular method. MBL(+) means the positive result of phenotypic test but no molecular identification. CIM(+) means the positive carbapenem inactivation test but no phenotypic or molecular identification (KPC—Klebsiella pneumoniae carbapenemase, OXA-48—oxacillinase-48, GES—Guiana extended-spectrum, NDM—New Delhi metallo-β-lactamase, VIM—Verona integron-encoded metallo-β-lactamase, MBL—metallo-β-lactamase, and CIM—carbapenem inactivation method).
