Eggerthella is a bacterial genus of Actinomycetota, in the family Coriobacteriaceae. Members of this genus are anaerobic, non-sporulating, non-motile, Gram-positive bacilli that grow singly, as pairs, or in short chains. They are found in the human colon and feces and have been implicated as a cause of ulcerative colitis, liver and anal abscesses and systemic bacteremia.
Aggregatibacter actinomycetemcomitans is a Gram-negative, facultative anaerobe, nonmotile bacterium that is often found in association with localized aggressive periodontitis, a severe infection of the periodontium. It is also suspected to be involved in chronic periodontitis. Less frequently, A. actinomycetemcomitans is associated with nonoral infections such as endocarditis. Its role in aggressive periodontitis was first discovered by Danish-born periodontist Jørgen Slots, a professor of dentistry and microbiology at the University of Southern California School of Dentistry.
Bacillus odysseyi is a Gram-positive, aerobic, rod-shaped, round-spore- and endospore-forming eubacterium of the genus Bacillus. This novel species was discovered by scientist Myron T. La Duc of NASA’s Biotechnology and Planetary Protection Group, a unit whose purpose is to clean and sterilize spacecraft so as not to have microorganisms contaminate other celestial bodies or foreign microorganisms contaminate Earth, on the surface of the Mars Odyssey in a clean room at the Jet Propulsion Laboratory in La Cañada Flintridge before the spacecraft was launched to space. La Duc named the bacterium Bacillus odysseyi sp. nov. after the Odyssey mission. It had apparently evolved to live in the sparse environment of a clean room, and its secondary spore coat makes it especially resistant to radiation.
Bifidobacterium longum is a Gram-positive, catalase-negative, rod-shaped bacterium present in the human gastrointestinal tract and one of the 32 species that belong to the genus Bifidobacterium. It is a microaerotolerant anaerobe and considered to be one of the earliest colonizers of the gastrointestinal tract of infants. When grown on general anaerobic medium, B. longum forms white, glossy colonies with a convex shape. B. longum is one of the most common bifidobacteria present in the gastrointestinal tracts of both children and adults. B. longum is non-pathogenic, is often added to food products, and its production of lactic acid is believed to prevent growth of pathogenic organisms.
Thermoanaerobacter is a genus in the phylum Bacillota (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as Clostridium species and members of the now obsolete genera Acetogenium and Thermobacteroides
Thermoanaerobacter brockii, formerly Thermoanaerobium brockii, is a thermophilic, anaerobic, spore-forming bacterium.
Peptoclostridium acidaminophilum is a Gram-positive bacterium species in the family Peptostreptococcaceae, notable for being an amino acid-degrading obligate anaerobe producing or utilizing H2 or formate. It is rod-shaped and motile by a polar to subpolar flagellum. Its type strain is al-2. It produces several relevant enzymes.
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.
Finegoldia is a genus of Gram-positive bacteria. They are anaerobic cocci of the class Clostridia, with Finegoldia magna being the type species. F. magna was formerly known, along with several other Gram-positive anaerobic cocci (GPACs), as Peptostreptococcus magnus, but was moved into its own genus in 1999. The name is in honor of Sydney M. Finegold, an American microbiologist, while magna is Latin for large. It is an opportunistic human pathogen that normally colonizes skin and mucous membranes. It is often seen in biofilms on chronic ulcers such as in diabetic foot or decubitus ulcers. Most surveys have found it to be susceptible to penicillins, carbapenems and metronidazole, though resistant strains have been identified. Resistance to clindamycin is common and has been seen in over 10% of isolates in the US. One review stated that "the combination of diminished antimicrobial susceptibility, its prevalence, and the described virulence factors gives F. magna a special position among the GPAC."
Anaerostipes hadrus is a Gram-positive bacterium from the genus of Anaerostipes which has been isolated from human faeces.
Lachnoanaerobaculum saburreum is a bacterium from the genus of Lachnoanaerobaculum which has been isolated from human dental plaque.

Holdemania is a Gram-positive, strictly anaerobic and non-spore-forming genus from the family of Erysipelotrichaceae, with two known species: Holdemania filiformis and Holdemania massiliensis.
Agathobacter rectalis is a Gram-positive, butyrate-producing, anaerobic, rod-shaped and non-spore-forming bacterium from the genus of Agathobacter with a single flagellate which occur in the rumen content of sheep and cows.
Dorea is a Gram-positive and nonspore-forming bacterial genus from the family Lachnospiraceae, which occur in human faeces.
Faecalicatena is a bacterial genus from the family of Lachnospiraceae.
Eubacterium aggregans is a Gram-positive, homoacetogenic, non-spore-forming and anaerobic bacterium from the genus of Eubacterium which has been isolated from olive mill wastewater in Tunisia
Absiella argi is a Gram-positive bacterium from the genus of Absiella which has been isolated from the feces of a dog.
Flavonifractor plautii is a bacterium of the monotypic genus Flavonifractor in the family Oscillospiraceae.
Clostridium vulturis is a gram-positive, rod-shaped, spore-forming, anaerobic bacterium, originally found in the intestine of a cinereous vulture in Korea. Part of the Clostridium genus, C. vulturis is closely related to Clostridium subterminale, Clostridium thiosulfatireducens, Clostridium sulfidigenes, and Clostridium amazonense.
