The Legionellales are an order of Proteobacteria. Like all Proteobacteria, they are Gram-negative. They comprise two families, typified by Legionella and Coxiella, both of which include notable pathogens. For example, Q fever is caused by Coxiella burnetii and Legionella pneumophila causes Legionnaires' disease and Pontiac fever.
Limnobacter is a genus of Gram-negative, non-spore-forming, aerobic, oxidase- and catalase-positive, motile bacteria with a single polar flagellum, of the family Burkholderiaceae and class Betaproteobacteria. Limnobacter species have the ability to oxidize thiosulfate.
Legionella beliardensis is a Gram-negative, catalase-positive, non-spore-forming, aerobic bacterium from the genus Legionella with a single polar flagellum, which was isolated from water from heating apparatus in Montbéliard in France.
Legionella brunensis is a Gram-negative, non-spore-forming, aerobic bacterium from the genus Legionella, which was isolated from cooling tower water in Czechoslovakia.
Legionella busanensis is a Gram-negative, catalase- and oxidase-positive bacterium from the genus Legionella with a single subpolar flagellum, which was isolated from cooling tower water in Busan in Korea.
Legionella cherrii is an aerobic, flagellated, Gram-negative bacterium from the genus Legionella. It was isolated from a heated water sample in Minnesota. L. cherrii is similar to another Legionella species, L. pneumophila, and is believed to cause major respiratory problems.
Legionella drozanskii is a Gram-negative, catalase-positive, oxidase-negative bacterium from the genus Legionella which was isolated from tank well water in Leeds in England.
Legionella fallonii is a Gram-negative, catalase-positive, weakly oxidase-positive bacterium from the genus Legionella which was isolated from a ship air-conditioning system.
Legionella gresilensis is a Gram-negative, aerobic, catalase-positive, non-spore-forming bacterium with a polar flagellum from the genus Legionella which was isolated from a shower from thermal spa water in the city Gréoux-les-Bains.
Legionella israelensis is a Gram-negative, oxidase-negative, catalase-positive, motile bacterium from the genus Legionella which was isolated from water from an oxidation pond in Ga'ash in Israel.
Legionella jordanis is a Gram-negative bacterium from the genus Legionella which was isolated from the Jordan River in Bloomington, Indiana and from the sewage in DeKalb County, Georgia. L. jordanis is a rare human pathogen and can cause respiratory tract infections.
Legionella moravica is a Gram-negative bacterium from the genus Legionella which was isolated from cooling-tower water samples in Czechoslovakia.
Legionella nagasakiensis is a Gram-negative bacterium from the genus Legionella which was isolated from a sample of hot spring water in Aomori in Japan and from human lung tissue. It is catalase-positive and rod-shaped, with a single polar flagellum.
Legionella parisiensis is a Gram-negative bacterium from the genus Legionella which was isolated from cooling tower water in Paris.
Legionella quinlivanii is a Gram-negative bacterium from the genus Legionella which was isolated from a cooling tower pond in London in United Kingdom.
Legionella rowbothamii is a Gram-negative, catalase-positive, oxidase-negative bacterium from the genus Legionella which was isolated from water and sludge from an industrial liquifier tower. Discovered by Tim Rowbotham.
Legionella taurinensis is a Gram-negative, oxidase- and catalase-positive bacterium from the genus Legionella with a single polar flagellum which was isolated from a water from a hospital oxygen bubble humidifier in Turin in Italy.
Legionella waltersii is a Gram-negative catalase- and oxidase-positive bacterium from the genus Legionella with a single polar flagellum which was isolated from a drinking water distribution system in Adelaide in Australia. L. waltersii is named after Reginald P. Walters. Legionella waltersii may can cause pneumonia.
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Firmicutes. 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.
Laceyella is a Gram-positive, thermophilic, spore-forming and aerobic bacterial genus from the family of Thermoactinomycetaceae. The genus Laceyella is namened after the English microbiologist John Lacey.
