A typical coccobacillus with short rod-shaped gram-negative bacterium which is lack of a whip-like structures used for locomotion yet exhibits swarming motility due to the presence of pole-like formation that can be retracted and extended.

Acinetobacter baumannii is a pleomorphic water organism that preferentially colonizes aquatic environments which is commonly isolated from irrigating solutions and intravenous solutions. It is lack cytochrome C oxidase and produces at least one beta-lactamase an enzyme responsible for cleaving atom lactam.

Acinetobacter baumannii has low virulence but competent of causing infection in organ transplant andfebrile neutropenia where most of the isolates recovered from hospital specifically from respiratory secretions and urine which shows colonization rather than infection. It has properties liketoxins that deliver to the system which directly affect host cell and qualities that contribute to the microbe fitness in surviving the host environment.

Acinetobacter baumannii is medically important particularly in a hospital-derived infections where it can be an opportunistic pathogen in humans in which occurs as outbreaks. Its infections complicate continuous ambulatory peritoneal dialysis or caused catheter linked bacteria.
