Legionella longbeachae is one species of the family Legionellaceae. It was first isolated from a patient in Long Beach, California. It is found predominantly in potting soil and compost. In humans, the infection is sometimes called Pontiac fever. Human infection from L. longbeachae is particularly common in Australia, but cases have been documented in other countries including the United States, Japan, Greece and the UK.
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 cincinnatiensis is a Gram-negative, non-spore-forming, aerobic bacterium from the genus Legionella which was isolated in Cincinnati from an open lung biopsy specimen from a patient who had hemodialysis because of an end-stage renal disease and suffered from bronchopneumonia.
Legionella dresdenensis is a Gram-negative, oxidase-negative, aerobic, non-spore-forming bacterium from the genus Legionella which was isolated from the Elbe in Dresden in Germany.
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 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 londiniensis is a Gram-negative bacterium from the genus Legionella which was isolated from hot spring water in Shizuoka in Japan.
Legionella massiliensis is a Gram-negative bacterium from the genus Legionella which was isolated from water from a cooling tower in Bouches du Rhone in France.
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 nautarum is a Gram-negative bacterium from the genus Legionella which was isolated from a hot water tap in London.
Legionella sainthelensi is a Gram-negative, catalase- and oxidase-positive, non-spore-forming, motile bacterium from the genus Legionella which was isolated from fresh water in regions influenced by the volcanic eruptions of Mount St. Helens in Washington. L. sainthelensi can cause infection in the respiratory tract.
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 wadsworthii is a bacterium from the genus Legionella isolated from sputum from a patient in Los Angeles. It can cause pneumonia in humans.
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.
Legionnaires' disease is a form of atypical pneumonia caused by any species of Legionella bacteria, quite often Legionella pneumophila. Signs and symptoms include cough, shortness of breath, high fever, muscle pains, and headaches. Nausea, vomiting, and diarrhea may also occur. This often begins 2–10 days after exposure.
Legionella norrlandica is a bacterium from the genus Legionella which has been isolated from a biopurification system.
