Legionella shakespearei sp. nov., isolated from cooling tower water

Int J Syst Bacteriol. 1992 Jul;42(3):404-7. doi: 10.1099/00207713-42-3-404.


A Legionella-like organism (strain 214T [T = type strain]) was isolated from a cooling tower in Stratford-upon-Avon, England. This strain required L-cysteine and contained cellular branched-chain fatty acids that are typical of the genus Legionella. Strain 214T produced pink colonies on buffered charcoal-yeast extract agar. Ubiquinone Q-12 was the major quinone. Strain 214T was serologically distinct from other legionellae as determined by a slide agglutination test. The results of DNA hybridization studies showed that strain 214T (= ATCC 49655T) is a member of a new Legionella species, Legionella shakespearei.
