Plasmid profiles of Legionella spp. isolates, Italy.
Plasmid analysis and restriction-endonuclease digestion were used to study 54 clinical and environmental Legionella strains. Plasmids with approximate molecular masses of 40, 50, 70, and 90 megadaltons (Mdal) have been isolated from L. pneumophila serogroup 1 strains. One L. jordanis strain contained two plasmids of 25 and 70 Mdal. Restriction analysis of clinical and related hospital-environmental isolates resulted in identical patterns. Geographic diversity is shown for strains of different origin.
