Suicide plasmid pSWΔFGm was transferred conjugally from E. coli donor into P. aeruginosa recipients SWSce (contains I-SceI-expressing plasmid) or SW658 (contains parent plasmid pJB658). After overnight mating at 37°C, transconjugants were plated onto minimal medium containing Sm, Gm, and Cb with or without Ura. Data are recorded as number of Smr, Gmr, and Cbr isolates per 108 recipients. Representative isolates were tested for Suc and FOA sensitivity.
