Acinetobacter is a genus of Gram-negative bacteria belonging to the wider class of Gammaproteobacteria. Acinetobacter species are oxidase-negative, exhibit twitching motility, and occur in pairs under magnification.
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. A. calcoaceticus is a part of the A. calcoaceticus-A. baumannii complex together with Acinetobacter baumannii, Acinetobacter nosocomialis, Acinetobacter pitti and Acinetobacter seifertii.
Acinetobacter baumannii is a typically short, almost round, rod-shaped (coccobacillus) Gram-negative bacterium. It is named after the bacteriologist Paul Baumann. 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. While other species of the genus Acinetobacter are often found in soil samples, it is almost exclusively isolated from hospital environments. Although occasionally it has been found in environmental soil and water samples, its natural habitat is still not known.
Acinetobacter haemolyticus is a species of bacterium. Its type strain is ATCC 17906. It is potentially pathogenic.
Acinetobacter junii is a species of bacteria. Its type strain is ATCC 17908. It can be pathogenic. This bacterium has been linked to nosocomial infections including catheter-related blood stream infections and cellulitis.
Acinetobacter beijerinckii is a gram-negative, strictly aerobic bacterium from the genus of Acinetobacter which was isolated from human and animal specimens and from different environmental sources.
Acinetobacter bereziniae is a gram-negative, strictly aerobic bacterium from the genus Acinetobacter.
Acinetobacter boissieri is a gram-negative, oxidase-negative, catalase-positive, strictly aerobic nonmotile bacterium from the genus Acinetobacter which was isolated from plants' floral nectar pollinated by wild Mediterranean insects. Acinetobacter boissieri is named after botanist Pierre Edmond Boissier.
Acinetobacter guillouiae is a gram-negative, strictly aerobic bacterium from the genus Acinetobacter isolated from gasworks effluent.
Acinetobacter gyllenbergii is a gram-negative, oxidase-negative, catalase-positive, strictly aerobic nonmotile bacterium from the genus Acinetobacter isolated from human clinical specimens. It is named in honour of Finnish bacteriologist and taxonomist Helge G. Gyllenberg.
Acinetobacter indicus is a gram-negative, oxidase-negative, catalase-positive, strictly aerobic nonmotile bacterium from the genus Acinetobacter isolated from a hexachlorocyclohexane dump site in Ummari near Lucknow in India.
Acinetobacter nosocomialis is a gram-negative, strictly aerobic bacterium from the genus Acinetobacter isolated from a patient at MetroHealth in Cleveland, Ohio. Acinetobacter nosocomialis belongs to the Acinetobacter calcoaceticus-baumannii complex.
Acinetobacter parvus is a Gram-negative, oxidase-negative, strictly aerobic bacterium from the genus Acinetobacter isolated from human clinical specimens.
Acinetobacter rudis is a Gram-negative, strictly aerobic bacterium from the genus Acinetobacter isolated from raw milk and wastewater.
Acinetobacter seifertii is bacterium from the genus Acinetobacter which has been isolated from human clinical specimens.
Acinetobacter variabilis is a bacterium from the genus Acinetobacter which has been isolated from human urine in Malmö in Sweden.
Acinetobacter colistiniresistens is a bacterium from the genus of Acinetobacter which has been isolated from human infections.
Acinetobacter dijkshoorniae is a bacterium from the genus of Acinetobacter.
Acinetobacter baylyi is a bacterial species of the genus Acinetobacter. The species naming designation was given after the discovery of strains in activated sludge in Victoria, Australia, in 2003. A. baylyi is named after the late Dr. Ronald Bayly, an Australian microbiologist who contributed significantly to research on aromatic compound catabolism in diverse bacteria, including strains of Pseudomonas, Alcaligenes, and Acinetobacter. The new species designation in 2003 was found to apply to an already well-studied Acinetobacter strain known as ADP1, a derivative of a soil isolate characterized in 1969. Strain ADP1 was previously designated Acinetobacter sp. and Acinetobacter calcoaceticus. Research, particularly in the field of genetics, has established A. baylyi as a model organism.
Acinetobacter guerrae is a species of Gram-negative bacteria of the genus Acinetobacter that was described in 2020. The species was described based on the characterization of two strains, isolated from raw chicken meat, in Porto, Portugal. Additionally, two publicly available draft genome sequences were also identified as members of A. guerrae, one of them isolated from human sputum in Kanagawa, Japan, and one isolated from hospital sewage in Sichuan, China. The draft genome sequence of the type strain is deposited in DNA Data Bank of Japan, European Nucleotide Archive, and GenBank under the accession number LXGN00000000
