Acinetobacter calcoaceticus
Acinetobacter calcoaceticus is a bacterial species of the genus Acinetobacter. It is a nonmotile, gram negative coccobacillus. It grows under aerobic conditions, is catalase positive and oxidase negative. It is part of the normal human intestinal flora. Together with A. baumannii, it is referred to as the A. calcoaceticus-A. baumannii complex, which is relatively simple to identify based on the beforementioned phenotypic characteristics. To identify other Acinetobacter species genotyping is required.
