Enlarge / This Scanning Electron Microscope image depicts several clusters of aerobic Gram-negative, non-motile Acinetobacter baumannii bacteria under a magnification of 24,730x. Members of the genus Acinetobacter are nonmotile rods, 1-1.5µm in diameter, and 1.5-2.5µm in length, becoming spherical in shape while in their stationary phase of growth. This bacteria is oxidase-negative and therefore does not utilize oxygen for energy production. They also occur in pairs under magnification. Acinetobacter spp. are widely distributed in nature, and are normal flora on the skin. Some members of the genus are important because they are an emerging cause of hospital acquired pulmonary, i.e., pneumoniae, hemopathic, and wound infections. Because the organism
