Transduction experiments of tetracycline resistance were carried out on staphylococcus aureus of typing pattern 29/52/80/81, tetracycline (TC)-streptomycin (SM) -sensistive, penicillin (PC) -resistant, and phage type 29/52/52A/80/81 (TC-, SM-, PC-, sensistive) strains with the prophages obtained from strains of phage type 80/81 and phage type 52/80/81, which are TC-, SM-, PC-reristant.
It was observed that recipient strains aquired the TC resistance and also changed the typing pattern into that of the donors, losing the sensitivity to the typing phages 29, 29/52 and 29/ 52/52A. However, the transduction of SM-resistance did not accompanied a chnge of typing pattern.
These results suggest that the genetic factor governing the TC-resistance is closely linked to that of phage typing pattern 29.
