Investigation of Metallo Beta Lactamases and Oxacilinases in Carbapenem Resistant Acinetobacter baumannii Strains Isolated from Inpatients

Only OXA 23-like carbapenemase was responsible for carbapenem resistance in carbapenem-resistant Acinetobacter strains in Edirne. The MBL-producing Acinetobacter strain is not yet a problem in our hospital. MBL resistance was found by phenotyping tests, which must be confirmed by genotypic methods; multiplex PCR tests can be easily used for screening MBL.
