ABSTRACT
Penicillin resistance plasmid was transferred from Staphylococcus aureus B4 (PcrKms, donor) to S. aureus ML351 (PcsKmr, recipient) by co-cultivation of the donor with the recipient in nutrient broth with or without the modifying effects of CaCl2 or sodium dodecyl sulfate. It was found that the transfer of drug-resistance occurred maximally between 6 and 18 hr postinoculation; however, addition of DNase (200 micrograms/ml) could totally prevent such a transfer up to 6 hr and significantly reduce it thereafter. Cell-free filtrate of the donor culture when mixed with the recipient was ineffective in bringing about the transfer of Pcr.
