Recognition of a second serogroup of Legionella longbeachae

J Clin Microbiol. 1981 Dec;14(6):674-7. doi: 10.1128/jcm.14.6.674-677.1981.


A strain of Legionella longbeachae (Tucker 1) that was isolated from the postmortem lung tissue of a pneumonia patient was serologically distinct from four other strains of L. longbeachae. The recognition of a second serogroup of L. longbeachae represents the first reported instance of serogroup diversity within a species of Legionella other than L. pneumophila. The disease caused by the Tucker 1 strain does not seem to be readily distinguishable from that of pneumonia caused by other legionellae.
