Horizontal gene transfer: a vehicle for the dissemination of resistance and virulence determinants during colonization and disease

The successful in vivo horizontal transfer of mobile genetic elements carrying resistance and virulence determinants have contributed immensely to a global dissemination of virulent and multi-drug resistant pathogens. In addition, the pathogenesis of MRSA infection is enhanced via initial colonizati...
