Methicillin-Resistant Staphylococcus Aureus
Methicillin-resistant Staphylococcus aureus is a bacterium responsible for several difficult-to-treat infections in humans. MRSA is any strain of Staphylococcus aureus that has developed, through horizontal gene transfer and natural selection, multi- resistance to beta-lactam antibiotics, which include the penicillins and the cephalosporins. MRSA evolved from horizontal gene transfer of the mecA gene to at least five distinct S. aureus lineages.
