SEM depicts a number of clusters of aerobic Gram-negative, non-motile Acinetobacter baumannii bacteria under a relatively low magnification of 1,546x. Members of the genus Acinetobacter are nonmotile rods, 1-1.5Ám in diameter, and 1.5-2.5Ám 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. Acinetobacter baumannii is a species of pathogenic bacteria, referred to as an aerobic gram-negative bacterium, that is resistant to most antibiotics. As a result of its resistance to drug treatment, some estimates state the disease is killing tens of thousands of US hospital patients each year. The illness can cause severe pneumonia and infections of the urinary tract, bloodstream and other parts of the body .A. baumannii forms opportunistic infections. There have been many reports of A. baumannii infections among American soldiers wounded in Iraq, earning it the nickname "Iraqibacter". Multidrug-resistant Acinetobacter baumannii is abbreviated as MDRAB.
