Phage Transduction of Staphylococcus aureus.

Bacteriophage transduction is the major mechanism of horizontal gene transfer (HGT) among many bacteria. In Staphylococcus aureus, the phage-mediated acquisition of mobile genetic elements (MGEs) that encode virulence and antibiotic resistance genes largely contribute to its evolutionary adaptation and genetic plasticity. In molecular biology, generalized transduction is routinely used as a technique to manipulate and construct bacterial strains. Here, we describe optimized protocols for generalized transduction, applicable for the transfer of plasmid or chromosomal deoxyribonucleic acid (DNA) from donor to recipient S. aureus strains.
