Autogenous transduction of phi 11de in Staphylococcus aureus: transfer and genetic properties.

AUTOR(ES)
RESUMO

The staphylococcal plasmid phi 11de is capable of transduction in the absence of both a helper bacteriophage and detectable plaque-forming bacteriophage. The mechanism of transfer is distinct from generalized transduction in that it does not transduce chromosomal material and is selective with respect to the plasmid DNA that is transduced. The transductants containing phi 11de have the following characteristics: (i) erythromycin resistance at levels displayed by the donor, (ii) expression of and susceptibility to plasmid incompatibility, (iii) dependence upon the host recombination system during transduction, (iv) complementation of phi 11 mutants, and (v) reactivation of UV-irradiated phage.
