Question

Include gram reaction and microscopic morphology: description on primary plating media and any appropriate specialized media : benchside rapid tests: biochemical tests and any appropriate automated systems

ORGANISM IS ACINETOBACTER BAUMANNI

Answer 1

Acinetobacter baumannii is an opportunistic bacterial pathogen linked with hospital-acquired infections and ubiquitously found in soil and water.

A. baumannii is a Gram-negative coccobacillus, strictly aerobic, pleomorphic, non-fastidious, non-fermenting, and non-motile bacteria.

They are biochemically tested as catalase-positive, and oxidase-negative

Luria-Bertani agar or LB agar is used as primary plating media to culture it. However, specialized minimal media enriched with calcium acetate is used as special media for its isolation from the soil.
