Acinetobacter the aerobic non fermenting GNCB are emerging as important pathogens in health care associated infection, exhibiting increased antimicrobial resistance by virtue of multiple resistant mechanisms with practically no therapeutic options. The objective was to determine the multitude of resistant mechanisms by phenotypic and genotypic characterization and the prevalent antimicrobial susceptibility pattern. 175 clinically significant non-duplicate Acinetobacter isolates were included. ESBL, AmpC and carbapenamase production were determined by CLSI phenotypic confirmatory method, AmpC disc test, Modified Hodge test and Imipenem-EDTA combined disc test respectively. | Phenotypic and molecular characterization of carbapenamase among acinetobacter isolates in a tertiary care hospital Tamil Nadu India
