Methicillin Resistant Staphylococcus Aureus (MRSA) and Its Different Testing Methods: A Review
Abstract: Staphylococcus aureus, a gram-positive bacterium is a serious current health care concern. In the mid-1980s, S. aureus strains emerged that were resistant to the beta-lactamase-stable penicillin, these strains were termed methicillin resistant S. aureus (MRSA). Methicillin resistance in S. aureus is primarily mediated by the mecA gene, which codes for the modified penicillin-binding protein 2a. MRSA strain has become one of the well-known etiologic agents for a wide variety of …
