The genes responsible for inducible erythromycin resistance in a set of DU 4916‐strains of Staphylococcus aureus were eliminated spontaneously or after exposure to ethidium bromide or heat. In transductions they were transferred into wildtype (rec+) and recombinationless (rec ‐ ) strains at similar frequencies. If rec+ strains were used as recipients, the transfer frequencies of inducible erythromycin resistance would not be stimulated after increasing doses of ultraviolet irradiation of the phage lysate, whereas the transfer frequency of chromosomal cadmium resistance would be tenfold stimulated. These facts support the suggestion that the genes for inducible erythromycin resistance are carried on a plasmid. Treatments with acriflavine or ethidium bromide could not elucidate the connection with methicillin‐ and inducible erythromycin resistance.
