title: [Conjugative plasmid transfer in Staphylococcus aureus?].
abstract: The microbiological and electron-microscopic study of the transfer of conjugative (pG873) and nonconjugative (rms7 and pE994) plasmids in two systems, on nitrocellulose filters and in a fluid culture medium, was carried out. In both systems the low frequency of the transfer of plasmid pG873 or the absence of the transfer of plasmids rms7 and pE994 were observed when nonlysogenic recipients were used for crossing. The presence of prophage in recipient cells increased the rate of the detection of gentamicin-sensitive transconjugants 100-fold and provided to reveal the transfer rms7 and pE994 plasmids. The electron-microscopic study of specimens with lysogenic recipients revealed a picture which can be interpreted as the fusion of two cells. Such picture was not observed in crossings with a nonlysogenic recipient and in preparations obtained from separate donor and recipient cultures.
