Acinetobacter is a group of bacteria generally considered nonpathogenic to healthy individuals. However, at least 23 species have been associated with human disease. Acinetobacter infections have increased and gained attention because of the organism’s prolonged environmental survival and propensity to develop antimicrobial drug resistance. The settings for infection are usually medical or surgical intensive care units involving patients with preexisting conditions. Common routes of bacterial transmission include contaminated medical devices such as ventilation devices and catheters.
