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.
Elizabethkingia meningoseptica is a Gram-negative, rod-shaped bacterium widely distributed in nature. It may be normally present in fish and frogs; it may be isolated from chronic infectious states, as in the sputum of cystic fibrosis patients. In 1959, American bacteriologist Elizabeth O. King was studying unclassified bacteria associated with pediatric meningitis at the Centers for Disease Control and Prevention in Atlanta, when she isolated an organism that she named Flavobacterium meningosepticum. In 1994, it was reclassified in the genus Chryseobacterium and renamed Chryseobacterium meningosepticum(chryseos = "golden" in Greek, so Chryseobacterium means a golden/yellow rod similar to Flavobacterium). In 2005, a 16S rRNA phylogenetic tree of Chryseobacteria showed that C. meningosepticum along with C. miricola were close to each other but outside the tree of the rest of the Chryseobacteria and were then placed in a new genus Elizabethkingia named after the original discoverer of F. meningosepticum.
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.
Enterobacter cloacae is a clinically significant Gram-negative, facultatively-anaerobic, rod-shaped bacterium.
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 ursingii is a species of potentially pathogenic bacteria. Its type strain is LUH 3792T.
Pedobacter soli is a species of Gram-negative bacteria, first isolated from rhizosphere soil of Brassica campestris, hence its name. Its type strain is 15-51(T).
Acinetobacter brisouii is a gram-negative, strictly aerobic, non-spore-forming, nonmotile bacterium from the genus Acinetobacter isolated from a peat layer on Yongneup in South Korea.
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 pittii is a Gram-negative, oxidase-negative, catalase-positive, strictly aerobic, nonmotile bacterium from the genus Acinetobacter. A. pittii belongs to the Acinetobacter calcoaceticus-baumannii complex and is named after the British microbiologist Tyrone Pitt. Bacteria of the genus Acinetobacter are ubiquitously distributed in nature. They are Gram-negative, strictly aerobic, nonmotile, diplococcoid rods that are oxidase negative and catalase positive. They are found in various types of soils and waters and are occasionally found in foodstocks. They are normal inhabitants of human skin and are capable of transitory colonization of the upper respiratory tract. They can cause infection in debilitated patients. DNA-DNA hybridization studies have been used to identify DNA groups within the genus Acinetobacter.
Acinetobacter rudis is a Gram-negative, strictly aerobic bacterium from the genus Acinetobacter isolated from raw milk and wastewater.
Acinetobacter apis is a gram-negative, obligate aerobic and non-motile bacterium from the genus Acinetobacter which has been isolated from the intestinal tract of the bee Apis mellifera. A. apis showed optimum growth at 25 degrees Celsius, pH 6-7, and in the presence of 1% (w/v) NaCl in trypticase soy broth medium. This bacterium was first characterized in 2014.
Acinetobacter guangdongensis is a gram-negative and non-motile bacterium from the genus Acinetobacter which has been isolated from a lead-zinc ore mine in Mei County in Meizhou in China.
Acinetobacter kookii is a gram-negative bacterium from the genus Acinetobacter which has been isolated from soil from Jeonju in Korea.
Belnapia soli is a Gram-negative, aerobic, non-spore-forming and non-motile bacterium from the genus of Belnapia which has been isolated from soil from Daejeon in Korea.
Parapedobacter soli is a Gram-negative, non-spore-forming, rod-shaped and non-motile bacterium from the genus of Parapedobacter which has been isolated from soil from a ginseng field in Korea.
