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.
Legionella adelaidensis is a Gram-negative, non-spore-forming, aerobic bacterium from the genus Legionella which was isolated from cooling tower water in Adelaide in South Australia.
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 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 feeleii is a Gram-negative, rod-shaped bacterium from the genus Legionella which was isolated from an automobile plant and which was held responsible for causing Pontiac fever in 317 workers. The organism did not grow on blood agar, required L-cysteine, and showed significant quantities of branched-chain fatty acids. More recently, an unusual, extrapulmonary case was described in a 66-year-old woman admitted to Hopital Nord, Marseille, France because of a complicated cellulitis and an abscess on her right leg following a suspected insect or spider bite.
Legionella gormanii is a Gram-negative bacterium from the genus Legionella which was isolated from soil samples from a creek bank in Atlanta and from the bronchial brush specimen of a patient who suffered from pneumonia. L. gormanii can cause atypical pneumonia together with L. pneumophila.
Legionella gratiana is a Gram-negative bacterium from the genus Legionella which was isolated from water in the Savoy region in France from a thermal spa.
Legionella hackeliae is a Gram-negative bacterium from the genus Legionella which was isolated from human lung aspirate in Pennsylvania.
Legionella londiniensis is a Gram-negative bacterium from the genus Legionella which was isolated from hot spring water in Shizuoka in Japan.
Legionella maceachernii is a Gram-negative bacterium from the genus Legionella which was isolated from a potable water cistern. L. maceachernii can cause pneumonia.
Legionella moravica is a Gram-negative bacterium from the genus Legionella which was isolated from cooling-tower water samples in Czechoslovakia.
Legionella nautarum is a Gram-negative bacterium from the genus Legionella which was isolated from a hot water tap in London.
Legionella parisiensis is a Gram-negative bacterium from the genus Legionella which was isolated from cooling tower water in Paris.
Legionella rubrilucens is a Gram-negative bacterium from the genus Legionella which was isolated from tap water in Los Angeles, hot spring water in Niigata in Japan, and a patient who suffered from pneumonia.
Legionella shakespearei is a Gram-negative, weakly oxidase-positive, catalase-positive bacterium with a single polar flagellum from the genus Legionella which was isolated from a cooling tower in Stratford-upon-Avon in England. L. shakespearei is named after William Shakespeare because it was isolated in Stratford-upon-Avon.
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 tucsonensis is a Gram-negative bacterium from the genus Legionella with a single polar flagellum, which was isolated from the pleural fluid of a renal transplant patient with immunosuppressive therapy in Tucson, Arizona.
Legionella worsleiensis is a bacterium from the genus Legionella which was isolated from industrial cooling tower in Worsley in England.
