The Vibrionaceae are a family of Pseudomonadota given their own order, Vibrionales. Inhabitants of fresh or salt water, several species are pathogenic, including the type species Vibrio cholerae, which is the agent responsible for cholera. Most bioluminescent bacteria belong to this family, and are typically found as symbionts of deep-sea animals.
Streptococcus bovis is a group of strains of Gram-positive bacteria, originally described as a species, that in humans is associated with urinary tract infections, endocarditis, sepsis, and colorectal cancer. S. bovis is commonly found in the alimentary tract of cattle, sheep, and other ruminants, and may cause ruminal acidosis. It is also associated with spontaneous bacterial peritonitis, a frequent complication occurring in patients affected by cirrhosis. Equivalence with Streptococcus equinus has been contested.
Aeromonas is a genus of Gram-negative, facultative anaerobic, rod-shaped, bacteria that morphologically resemble members of the family Enterobacteriaceae. Most of the 14 described species have been associated with human diseases. The most important pathogens are A. hydrophila, A. caviae, and A. veronii biovar sobria. The organisms are ubiquitous in fresh and brackish water.
Aliivibrio is a genus in the phylum Pseudomonadota (Bacteria).
Campylobacter concisus is a Gram-negative, highly fastidious, mesophilic bacterium that grows under both anaerobic and microaerobic conditions with the presence of hydrogen significantly aiding growth. Motile, with either unipolar or bipolar flagella, the organisms have a characteristic spiral/corkscrew appearance and are oxidase-positive. Although the human oral cavity is the natural colonization site of the bacterium, C. concisus may also colonize the intestinal tract of some individuals. In particular, several studies have reported higher intestinal prevalence of C. concisus in patients with IBD compared to healthy controls, which has led to current speculation of the bacterium's implication in the induction of Crohn's disease.
Vibrio furnissii is a Gram-negative, rod-shaped bacterium. Its type strain is ATCC 35016. V. furnissii is aerogenic (gas-producing), and uses L-rhamnose, L-arginine, L-arabinose, maltose, and D-mannitol, but not L-lysine, L-ornithine, or lactose. It has been isolated from patients with gastroenteritis, bacteremia, skin lesions, and sepsis.
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 ursingii is a species of potentially pathogenic bacteria. Its type strain is LUH 3792T.
Acinetobacter schindleri is a species of bacteria. It is potentially pathogenic. Its type strain is LUH 5832T.
Moraxella atlantae is a Gram-negative, oxidase-positive and catalase-positive, rod-shaped, nonmotile bacterium in the genus Moraxella. First described in 1976 it was recognized as a rare opportunistic pathogen in humans starting in 1991.
Leeuwenhoekiella is a strictly aerobic bacterial genus from the family of Flavobacteriaceae.
Globicatella sulfidifaciens is a Gram-positive bacteria from the family of Globicatella which has been isolated from the lungs of cattle and lambs in Belgium. It is associated with purulent infections of domestic mammals and urinary tracts of swine. Unlike other Globicatella species and species of related genera, G. sulfidifaciens is PYR negative. Globicatella sulfidifaciens bacteria are resistant against the antibiotics neomycin, erythromycin and clindamycin.
Neptunomonas is an anaerobic and rod-shaped genus of bacteria from the family of Oceanospirillaceae.
Janibacter is a genus of Gram positive, nonmotile, non-sporeforming bacteria. The genus name is derived from the two-faced Roman god Janus, referring to the fact that the cells of the original strain could be rod-shaped or coccoid.
Dokdonella koreensis is a Gram-negative, rod-shaped, non-spore-forming and motile bacterium from the genus of Dokdonella which has been isolated from soil from Dokdo in Korea. As of 2014, its pathogenicity in humans was unclear.
Ignatzschineria indica is a Gram-negative, aerobic, non-spore-forming and non-motile bacterium from the genus of Ignatzschineria which has been isolated from the gut content of flesh flies from Pune in India.
Bibersteinia is a Gram-negative and non-motile, genus of bacteria from the family of Pasteurellaceae with one known species. Bibersteinia is named after Ernst L. Biberstein. Bibersteinia trehalosi is a pathogen of sheep and can cause systemic infections in sheep.
Enterovibrio nigricans is a bacterium species from the genus of Enterovibrio which has been isolated from the head kidney of the fish Sparus aurata from the Mediterranean coast in Spain.
Neisseria animaloris, formerly named CDC group EF-4a, is a gram-negative coccoid rod. The bacterium is a commensal of the upper respiratory tract of cats and dogs, and they may cause pulmonary infections in cat. In humans Neisseria animaloris have been reported to cause wound infection after animal bites but also chronic otitis media, bacteremia and endophtalmitis.
Enterococcus casseliflavus is a species of commensal Gram-positive bacteria. Its name derived from the "flavus" the Latin word for yellow due to the bright yellow pigment that it produces. This organism can be found in the gastrointestinal tract of humans
