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.
Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. Over 700 species of Streptomyces bacteria have been described. As with the other Actinomycetota, streptomycetes are gram-positive, and have very large genomes with high GC content. Found predominantly in soil and decaying vegetation, most streptomycetes produce spores, and are noted for their distinct "earthy" odor that results from production of a volatile metabolite, geosmin. Different strains of the same species may colonize very diverse environments.
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.
Mycolicibacter kumamotonensis is a species of bacteria.
Etymology: kumamotonensis, pertaining to Kumamoto Prefecture in Japan, where the type strain was isolated.
The Selenomonadales are an order of bacteria within the class Negativicutes; unlike most other members of Bacillota, they are Gram-negative. The phylogeny of this order was initially determined by 16S rRNA comparisons. More recently, molecular markers in the form of conserved signature indels (CSIs) have been found specific for all Selenomonadales species. On the basis of these markers, the Selenomonadales are inclusive of two distinct families, and are no longer the sole order within the Negativicutes. Several CSIs have also been found specific for both families, Sporomusaceae and Selenomonadceae. Samples of bacterial strains within this order have been isolated from the root canals of healthy human teeth.
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 bereziniae is a gram-negative, strictly aerobic bacterium from the genus Acinetobacter.
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 pittii is a Gram-negative, oxidase-negative, catalase-positive, strictly aerobic, nonmotile, diplococcoid rod bacterium from the genus Acinetobacter. DNA-DNA hybridization studies have been used to identify DNA groups within the genus Acinetobacter and A. pittii belongs to the Acinetobacter calcoaceticus-baumannii complex. The specific epithet pittii is named after the British microbiologist Tyrone Pitt.
Geobacter psychrophilus is a Fe(III)-reducing bacterium. It is Gram-negative, slightly curved, rod-shaped and motile via means of monotrichous flagella. Its type strain is P35T.
Streptococcus infantarius is a species of bacteria.
Mark J. Pallen is a research leader at the Quadram Institute and Professor of Microbial Genomics at the University of East Anglia. In recent years, he has been at the forefront of efforts to apply next-generation sequencing to problems in microbiology and ancient DNA research.
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 seifertii is bacterium from the genus Acinetobacter which has been isolated from human clinical specimens.
Acinetobacter dijkshoorniae is a bacterium from the genus of Acinetobacter.
Nitrospinota is a bacterial phylum. Despite only few described species, members of this phylum are major nitrite-oxidizing bacteria in surface waters in oceans. By oxidation of nitrite to nitrate they are important in the process of nitrification in marine environments.
Mycolicibacter heraklionensis is a species of bacteria from the phylum Actinomycetota. It is susceptible to clarithromycin. It is known to cause tenosynovitis in humans, but has also been isolated from sputum, urine, and a soft-tissue ankle mass.
