The presence of a 138-kilobase plasmid (pD188) correlated with increased resistance to cadmium in Rhodococcus fascians D188. This plasmid could be transferred by a conjugation-like system in matings between R. fascians strains. To examine this correlation we used large /sup 32/P-labeled pD188 subclones as probes in hybridization analyses with Southern blots of restricted total DNAs of D188 and its derivative mutants. Transconjugants expressed the cadmium resistance and could be used as donors in subsequent matings. Four other R. fascians strains (NCPPB 1488, NCPPB 1675, NCPPB 2551, and ATCC 12974) could also be used as donors for cadmium resistance in matings. Strain NCPPB 1675 showed a 100% cotransfer of cadmium and chloramphenicol resistance markers.
