Acinetobacter baumannii is a typically short almost round rod-shaped (coccobacillus) Gram-negative bacterium. It can be an opportunistic pathogen in humans affecting people with compromised immune systems and is becoming increasingly important as a hospital-derived (nosocomial) infection. It has also been isolated from environmental soil and water samples. Bacteria of this genus lack flagella whip-like structures many bacteria use for locomotion but exhibit twitching or swarming motility.
