The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
Polyptychodon is a genus of pliosaurid found in Middle-Late Cretaceous marine deposits in southern England and Patagonia. It has been considered a nomen dubium in a 2016 review.
The Synergistota is a phylum of anaerobic bacteria that show Gram-negative staining and have rod/vibrioid cell shape. Although Synergistota have a diderm cell envelope, the genes for various proteins involved in lipopolysaccharides biosynthesis have not yet been detected in Synergistota, indicating that they may have an atypical outer cell envelope. The Synergistota inhabit a majority of anaerobic environments including animal gastrointestinal tracts, soil, oil wells, and wastewater treatment plants and they are also present in sites of human diseases such as cysts, abscesses, and areas of periodontal disease. Due to their presence at illness related sites, the Synergistota are suggested to be opportunistic pathogens but they can also be found in healthy individuals in the microbiome of the umbilicus and in normal vaginal flora. Species within this phylum have also been implicated in periodontal disease, gastrointestinal infections and soft tissue infections. Other species from this phylum have been identified as significant contributors in the degradation of sludge for production of biogas in anaerobic digesters and are potential candidates for use in renewable energy production through their production of hydrogen gas. All of the known Synergistota species and genera are presently part of a single class (Synergistia), order (Synergistiales), and family (Synergistaceae).
The Chloroflexota are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
Jeotgalicoccus is a genus of Gram-positive, facultatively anaerobic, and halotolerant to halophilic bacteria. The cells are coccoid. The genus is named after the Korean fish sauce jeotgal, whence these bacteria were first isolated.
Deinococcus is in the monotypic family Deinococcaceae, and one genus of three in the order Deinococcales of the bacterial phylum Deinococcota highly resistant to environmental hazards. These bacteria have thick cell walls that give them Gram-positive stains, but they include a second membrane and so are closer in structure to Gram-negative bacteria. Deinococcus survive when their DNA is exposed to high doses of gamma and UV radiation. Whereas other bacteria change their structure in the presence of radiation, such as by forming endospores, Deinococcus tolerate it without changing their cellular form and do not retreat into a hardened structure. They are also characterized by the presence of the carotenoid pigment deinoxanthin that give them their pink color. They are usually isolated according to these two criteria. In August 2020, scientists reported that bacteria from Earth, particularly Deinococcus bacteria, were found to survive for three years in outer space, based on studies conducted on the International Space Station. These findings support the notion of panspermia, the hypothesis that life exists throughout the Universe, distributed in various ways, including space dust, meteoroids, asteroids, comets, planetoids or contaminated spacecraft.
Agromyces is a genus in the phylum Actinomycetota (Bacteria).
Brucella anthropi is a bacterium. The type strain is strain CIP 82.115. O. anthropi strains are rod-shaped, aerobic, gram-negative, non-pigmented and motile by means of peritrichous flagella. They are emerging as major opportunistic pathogens.
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Bacillota. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.
Brucella intermedia is a bacterium from the genus of Brucella. It was first described by Velasco and others in 1998. It causes diseases in humans only rarely, with single case reports of cholangitis following liver transplantation, bacteremia in a patient with bladder cancer, a pelvic abscess after abdominal surgery, dyspepsia, endophalmitis in the presence of a foreign body, pneumonia, and endocarditis.
Chryseobacterium anthropi is a Gram-negative bacteria from the genus of Chryseobacterium.
Chryseobacterium balustinum is a bacterium from the genus of Chryseobacterium which has been isolated from blood from a fish in Lausanne in Switzerland.
Mucilaginibacter is a genus from the family of Sphingobacteriaceae.
Roseomonas is a genus of Gram negative bacteria. The cells are coccoid rods when viewed microscopically. Certain species are known to be opportunistic infections for humans.
Varibaculum is a Gram-positive, facultatively anaerobic, non-spore-forming and non-motile genus of bacteria from the family of Actinomycetaceae.
Varibaculum cambriense is a Gram-positive and anaerobic bacterium from the genus of Varibaculum which has been isolated from a human postauricular abscess.
Luteibacter is a genus of bacteria from the family of Rhodanobacteraceae.
Jonquetella is a Gram-negative and strictly aerobic genus of bacteria from the family of Synergistaceae with one known species. Jonquetella anthropi has been isolated from a human cyst from Montpellier in France.
Ovaliviridae is a family of viruses of archaea that is not assigned to any higher taxonomic ranks. The family contains a single genus, Alphaovalivirus, which contains a single species, Sulfolobus ellipsoid virus 1. The linear genome of dsDNA is 23,219 bp with 172 bp inverted terminal repeats. Sulfolobus ellipsoid virus 1 was isolated from an acidic hot spring in Laguna Fumarólica, Costa Rica; the only known host is Sulfolobus sp. A20.
Tessaracoccus timonensis is a Gram-negative and non-motile bacterium from the genus of Tessaracoccus which has been isolated from vaginal swabs from Senegalese women.
