Plasmid profiles of selected V. vulnificus strains. Lanes: A, E. coli 39R861; B, E. coli V517; C, V. cholerae 1075/25; D, V. vulnificus CDC 9344-95; E, V. vulnificus CDC 9149-95; F, V. vulnificus CDC 9030-95; G, V. vulnificus CDC 9031-96; H, V. vulnificus CDC 9075-96. Strains in lanes E to H contain a band of approximately 40 kb that is a relaxed form of the 29-kb plasmid, and lane H also contains a relaxed form of the 6.9-kb plasmid.
