Acinetobacter seifertii is bacterium from the genus Acinetobacter which has been isolated from human clinical specimens. [1] [2] [3]
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.
Colistin, also known as polymyxin E, is an antibiotic medication used as a last-resort treatment for multidrug-resistant Gram-negative infections including pneumonia. These may involve bacteria such as Pseudomonas aeruginosa, Klebsiella pneumoniae, or Acinetobacter. It comes in two forms: colistimethate sodium can be injected into a vein, injected into a muscle, or inhaled, and colistin sulfate is mainly applied to the skin or taken by mouth. Colistimethate sodium is a prodrug; it is produced by the reaction of colistin with formaldehyde and sodium bisulfite, which leads to the addition of a sulfomethyl group to the primary amines of colistin. Colistimethate sodium is less toxic than colistin when administered parenterally. In aqueous solutions it undergoes hydrolysis to form a complex mixture of partially sulfomethylated derivatives, as well as colistin. Resistance to colistin began to appear as of 2015.
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.
Mycobacterium palustre is a slowly growing mycobacterium first isolated from an environmental source in Finland. It is potentially pathogenic, and has been isolated from human and veterinary clinical specimens.
Acinetobacter haemolyticus is a species of bacterium. Its type strain is ATCC 17906. It is potentially pathogenic.
Acinetobacter ursingii is a species of potentially pathogenic bacteria. Its type strain is LUH 3792T.
Acinetobacter schindleri is a species of bacteria. It is potentially pathogenic. Its type strain is LUH 5832T.
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 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 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 soli is a Gram-negative, catalase-positive, oxidase-negative, strictly aerobic rod-shaped, nonmotile bacterium from the genus Acinetobacter isolated from forest soil at Mt. Baekwoon in the Republic of Korea. . Acinetobacter soli can cause bloodstream infection in neonates.
Acinetobacter towneri is a Gram-negative, strictly aerobic bacterium from the genus Acinetobacter isolated from activated sludge in Bendigo in Australia.
Acinetobacter lwoffii, formerly known as Mima polymorpha or Acinetobacter calcoaceticus var. lwoffii, is a non-fermentative Gram-negative bacillus bacterium that is a member of the genus Acinetobacter. It is considered as normal skin flora and can also inhabit the human oropharynx and perineum of up to 25% of the population. In addition to that, it can cause infections in human hosts, particularly catheter-associated infections in immunocompromised patients. It has also been associated with at least one case of gastroenteritis. Due to its ability to survive dry conditions, low pH, and a wide range of temperatures, A. lwoffii, along with A. johnsonii, has been found in frozen food, bacon, eggs, pasteurized milk, and fish. It is also resistant to many disinfectants, irradiation, and desiccation. There are also many environmental A. lwoffii strains originating for instance from a permafrost or former gold mine.
Acinetobacter variabilis is a bacterium from the genus Acinetobacter which has been isolated from human urine in Malmö in Sweden.
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
Acinetobacter cumulans is a bacterium from the genus of Acinetobacter which has been isolated from hospital sewage from China. Acinetobacter cumulans is resistant against clinically important antibiotics.
