Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacteria that are resistant to antibiotics such as methicillin and cephalosporins. MRSA may cause serious infections to patients with open wounds, invasive devices, and weakened immune systems, which are in some cases extremely difficult to treat. In recent years, the rate of MRSA infections has been increasing globally and causing high morbidity, mortality, and healthcare cost.
