Escherichia coli, also known as E. coli, is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms. Most E. coli strains are harmless, but some serotypes (EPEC, ETEC etc.) can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. The harmless strains are part of the normal microbiota of the gut, and can benefit their hosts by producing vitamin K2, and preventing colonisation of the intestine with pathogenic bacteria, having a mutualistic relationship. E. coli is expelled into the environment within fecal matter. The bacterium grows massively in fresh fecal matter under aerobic conditions for three days, but its numbers decline slowly afterwards.
Vibrio cholerae is a species of Gram-negative, facultative anaerobe and comma-shaped bacteria. The bacteria naturally live in brackish or saltwater where they attach themselves easily to the chitin-containing shells of crabs, shrimps, and other shellfish. Some strains of V. cholerae are pathogenic to humans and cause a deadly disease cholera, which can be derived from the consumption of undercooked or raw marine life species.
Dichelobacter nodosus, formerly Bacteroides nodosus, is a Gram-negative, obligate anaerobe of the family Cardiobacteriaceae. It has polar fimbriae and is the causative agent of ovine foot rot as well as interdigital dermatitis. It is the lone species in the genus Dichelobacter.
Faecalibacterium is a genus of bacteria. Its sole known species, Faecalibacterium prausnitzii is gram-positive, mesophilic, rod-shaped, anaerobic and is one of the most abundant and important commensal bacteria of the human gut microbiota. It is non-spore forming and non-motile. These bacteria produce butyrate and other short-chain fatty acids through the fermentation of dietary fiber.
Lautropia mirabilis is a Gram-negative, facultatively anaerobic, oxidase- and catalase-positive, motile bacterium of the genus Lautropia and family Burkholderiaceae, isolated from the mouth of children who were infected with human immunodeficiency virus.
Desulfitobacterium hafniense is a species of gram positive bacteria, its type strain is DCB-2T..
Clostridium uliginosum is a mesophilic bacterium oxidizing acetate in syntrophic association with a hydrogenotrophic methanogenic bacterium. It is a spore-forming, gram-positive, rod-shaped organism, with type strain BST. Its genome has been sequenced.
Holophaga foetida is a bacterium, the type species of its genus. It is a homoacetogenic bacterium degrading methoxylated aromatic compounds. It is gram-negative, obligately anaerobic and rod-shaped, with type strain TMBS4. Its genome has been sequenced. It is known for its ability to anaerobically degrade aromatic compounds and the production of volatile sulfur compounds through a unique pathway.
Clostridioides difficile, also known as C. difficile, or C. diff, is Gram-positive species of spore-forming bacteria. Clostridioides spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. Its vegetative cells are rod-shaped, pleomorphic, and occur in pairs or short chains. Under the microscope, they appear as long, irregular cells with a bulge at their terminal ends. Under Gram staining, C. difficile cells are Gram-positive and show optimum growth on blood agar at human body temperatures in the absence of oxygen. C. difficile is catalase- and superoxide dismutase-negative, and produces up to three types of toxins: enterotoxin A, cytotoxin B and Cytolethal distending toxin. Under stress conditions, the bacteria produce spores that are able to tolerate extreme conditions that the active bacteria cannot tolerate.
Clostridium pasteurianum is a bacterium discovered in 1890 by the Russian microbiologist Sergei Winogradsky. It was the first free living (non-symbiotic) micro-organism discovered that could fix free nitrogen from the air.
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 butyraticus is a Gram-positive, butyrate-producing and anaerobic bacterium from the genus of Anaerostipes which has been isolated from the caecal content of a broiler chicken in Ghent in Belgium.
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 rhamnosivorans is a Gram-variable, strictly anaerobic, spore-forming, butyrate-producing and curly rod-shaped bacterium from the genus of Anaerostipes which has been isolated from the human faeces of an infant in the Netherlands.
Cellulosimicrobium cellulans is a Gram-positive bacterium from the genus of Cellulosimicrobium. Cellulosimicrobium cellulans can cause rare opportunistic infections. The strain EB-8-4 of this species can be used for stereoselective allylic hydroxylation of D-limonene to (+)-trans-carveol.
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.
