Legionella adelaidensis, a new species isolated from cooling tower water

J Clin Microbiol. 1991 May;29(5):1004-6. doi: 10.1128/jcm.29.5.1004-1006.1991.


A Legionella-like organism (strain 1762-AUS-E) was isolated from a cooling tower of an air-conditioning system in Adelaide, South Australia, Australia. The isolate was presumptively identified as a Legionella strain by its growth requirement for L-cysteine and its cellular branched-chain fatty acids. Strain 1762-AUS-E was serologically distinct in the slide agglutination test with absorbed antisera. DNA hybridization confirmed that it is a new Legionella species for which the name Legionella adelaidensis is proposed.
