MRSA isolates can rapidly transfer the methicillin resistance to other species of S<em>taphylococcus</em> and some other bacteria. Also <em>S. aureus</em> can acquire other antibiotic resistant genes making a deadly bacterium for its strong resistance. It is in search how the bacterium acquire this antibiotics resistance ( and other virulence factors genes) and the mechanism involve to develop new drugs to treat  MRSA infections  with the hope that can´t develop resistance to this new drugs.
