Characterization of a beta-lactamase-specifying plasmid isolated from Eikenella corrodens and its relationship to a commensal Neisseria plasmid

A 9.4-kilobase plasmid encoding penicillin, streptomycin, and sulfonamide resistance was isolated from a beta-lactamase-producing Eikenella corrodens strain. This plasmid appears to be identical to a resistance plasmid common to saprophytic Neisseria strains.
