Identification of Acinetobacter baumannii and determination of MDR and XDR strains

الملخص EN

The current study focuses on the bacterium Acinetobacter baumannii due to its importance as a nosocomial infections source in addition to its increased resistance against antibiotics.

Different clinical and hospital environment samples were collected, and cultured on A.

baumannii selective media: Leed Acinetobacter agar and Herellea agar.

A.

baumannii have been identified by traditional methods, followed by confirmation using molecular identification to detect blaoxa-51 like gene which is considered a diagnostic gene since it is present in genome of all A.

baumannii strains.

The result was, nineteen bacterial isolates of A.

baumannii were obtained, from twenty-seven suspected isolates, detection of local isolates belonging to MDR or XDR group.

Results demonstrated that all local isolates are MDR and 16 isolates (84.2 % ) are XDR.
