Bartonella is a genus of Gram-negative bacteria. It is the only genus in the family Bartonellaceae. Facultative intracellular parasites, Bartonella species can infect healthy people, but are considered especially important as opportunistic pathogens. Bartonella species are transmitted by vectors such as ticks, fleas, sand flies, and mosquitoes. At least eight Bartonella species or subspecies are known to infect humans.
Bartonella quintana, originally known as Rochalimaea quintana, and "Rickettsia quintana", is a bacterium transmitted by the human body louse that causes trench fever. This bacterial species caused outbreaks of trench fever affecting 1 million soldiers in Europe during World War I.
Pluralibacter gergoviae is a Gram-negative, motile, facultatively-anaerobic, rod-shaped bacterium. P. gergoviae is of special interest to the cosmetics industry, as it displays resistance to parabens, a common antimicrobial agent added to cosmetic products.
Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae. Several Cronobacter species are desiccation resistant and persistent in dry products such as powdered infant formula. They are generally motile, reduce nitrate, use citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter spp. are also generally positive for acetoin production and negative for the methyl red test, indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii comb. nov.
Cat-scratch disease (CSD) or felinosis is an infectious disease that most often results from a scratch or bite of a cat. Symptoms typically include a non-painful bump or blister at the site of injury and painful and swollen lymph nodes. People may feel tired, have a headache, or a fever. Symptoms typically begin within 3–14 days following infection.
Bartonella talpae, formerly belonging to the Grahamella genus, is a bacterium. As with other Bartonella species, it can cause disease in animals.
Bartonella peromysci, formerly belonging to the Grahamella genus, is a bacterium. As with other Bartonella species, it can cause disease in animals.
Bartonella grahamii is a bacterium. As with other Bartonella species, it can cause disease in animals.
Bartonella tribocorum is a bacterium. As with other Bartonella species, it can cause disease in animals.
Bartonella elizabethae, formerly known as Rochalimaea elizabethae, is a bacterium. As with other Bartonella species, it can cause disease in animals.
Leptospira alexanderi is a species of Leptospira. Its type strain is strain L 60T.
Afipia felis is the type species of the Afipia bacterial genus. It was formerly thought to cause cat-scratch disease. It is a Gram-negative, oxidase-positive, nonfermentative rod in the alpha-2 subgroup of the class Proteobacteria. It is motile by means of a single flagellum. It is noted for having the longest authority citation of any accepted species.
Afipia birgiae is a species in the Afipia bacterial genus. It is a gram-negative, oxidase-positive rod in the alpha-2 subgroup of the class Proteobacteria. It is motile by means of a single flagellum. Its type strain is 34632T.
Bartonella koehlerae is a bacterium first isolated from cats. Its genome consists of 1.7–1.8 Mb.
Ehrlichia muris is a species of pathogenic bacteria first isolated from mice, with type strain AS145T. Its genome has been sequenced.
Bartonella clarridgeiae is a Gram-negative bacteria from the genus Bartonella which was first isolated in the United States. Bartonella clarridgeiae is a zoonotic pathogen which can cause cat scratch disease.
"Candidatus Bartonella monaxi" is a candidatus bacteria from the genus of Bartonella which was isolated from groundhogs.
Sphingomonas asaccharolytica is a bacterium from the genus of Sphingomonas which has been isolated from roots from an apple tree in Japan.
Pluralibacter is a genus of Gram negative bacteria from the family of Enterobacteriaceae. The genus consists of two species, P. gergoviae and P. pyrinus. Both species were originally classified in the genus Enterobacter but were reclassified into the novel genus Pluralibacter in 2013.
Pluralibacter pyrinus is a Gram-negative, motile, facultatively-anaerobic, rod-shaped bacterium. P. pyrinus is the causitive agent of brown leaf spot disease of pear trees.
