In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall.
Ruminococcus is a genus of bacteria in the class Clostridia. They are anaerobic, Gram-positive gut microbes. One or more species in this genus are found in significant numbers in the human gut microbiota. The type species is R. flavefaciens. As usual, bacteria taxonomy is in flux, with Clostridia being paraphyletic, and some erroneous members of Ruminococcus being reassigned to a new genus Blautia on the basis of 16S rRNA gene sequences.
Clostridium lavalense is an anaerobic, motile, spore-forming, rod-shaped, gram-positive bacterium first isolated from human feces. The epithet "lavalense" refers to the institution, Université Laval, Québec, Canada.
Methanobrevibacter gottschalkii is a species of methanogen archaeon, named after Gerhard Gottschalk.
Methanobrevibacter thaueri is a species of methanogen archaeon, named after Rolf K. Thauer.
Methanobrevibacter woesei is a species of methanogen archaeon, named after Carl R. Woese.
Methanobrevibacter wolinii is a species of methanogen archaeon, named after Meyer J. Wolin.
Roseburia intestinalis is a saccharolytic, butyrate-producing bacterium first isolated from human faeces. It is anaerobic, gram-positive, non-sporeforming, slightly curved rod-shaped and motile by means of multiple subterminal flagella. L1-82T is the type strain.
Roseburia inulinivorans is a bacterium first isolated from human faeces. It is anaerobic, Gram-negative or Gram-variable, slightly curved rod-shaped and motile. The cells range in size from 0.5-1.5 to 5.0 micrometres. A2-194(T) is the type strain.
Roseburia hominis is a bacterium first isolated from human feces. It is anaerobic, Gram-negative or Gram-variable, slightly curved rod-shaped and motile. The cells range in size from 0.5-1.5 to 5.0 μm. A2-183(T) is the type strain.
Eubacterium acidaminophilum is a Gram-positive bacterium species in the genus Eubacterium, 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.
Levilinea saccharolytica is a mesophilic, non-spore-forming, non-motile, Gram-negative, filamentous bacteria with type strain KIBI-1T, the type species of its genus.
Victivallis vadensis is a Gram-negative, coccus-shaped, bacteria found in the human digestive tract. It measures approximately 0.5-1.3 micrometers in diameter, is non-motile and chemoorganotrophic, and does not form spores. Victivallis vadensis is strictly anaerobic, as are 90 percent of the bacteria in the human gastrointestinal system.
Anaerostipes is a Gram positive and anaerobic bacterial genus from the family of Lachnospiraceae. Anaerostipes occurs in the human gut. Anaerostipes may protect against colon cancer in humans by producing butyric acid.
Anaerostipes caccae is a Gram-variable, anaerobic saccharolytic, rod-shaped butyrate-producing and acetate and lactate-utilising bacterium from the genus of Anaerostipes which has been isolated from human faeces.
Anaerostipes hadrus is a Gram-positive bacterium from the genus of Anaerostipes which has been isolated from human faeces.
Anaerococcus is a genus of bacteria. Its type species is Anaerococcus prevotii. These bacteria are Gram-positive and strictly anaerobic. The genus Anaerococcus was proposed in 2001. Its genome was sequenced in August 2009. The genus Anaerococcus is one of six genera classified within the group GPAC. These six genera are found in the human body as part of the commensal human microbiota.
Parabacteroides faecis is a bacterium from the genus of Parabacteroides which has been isolated from human faeces.
Oscillospiraceae is a family of bacteria in the class Clostridia. All Oscillospiraceae are obligate anaerobes. However, members of the family have diverse shapes, with some rod-shaped and others cocci.
Bilophila wadsworthia is a gram-negative, obligately anaerobic, catalase-positive, bile-resistant, and asaccharolytic bacillus. This bacterium is about 0.7 μm wide by 1.0–10.0 μm long in colony and the cells are pleomorphic with irregular cell walls. This bacterial species is mostly urease positive; around 75% of the strains are urease positive. Less than 0.01% of the human gut microbiota is this bacterium. B. wadsworthia is linked to various diseases and is not well known due to frequent misidentification of the bacteria. The two unique characteristics of B. wadsworthia are the utilisation of the sulfated amino acid taurine in the production of hydrogen sulfide and the rapid catalase reaction. This bacterium is vulnerable to the antibiotics: imipenem, ceoxitin, and ticarcillin, which are all β-lactam antibiotics.
