Study Notes
Antimicrobial Resistance Testing
- Methicillin-resistant Staphylococcus aureus (MRSA): The mecA gene alters penicillin-binding protein 2a (PBP2a).
- Vancomycin-resistant Staphylococcus aureus (VRSA): Testing involves the Etest method.
- Extended-spectrum beta-lactamases (ESBL): Testing includes both a standard test and one with clavulanic acid.
- Clindamycin resistance: The erm gene is associated with this resistance.
- Carbapenemase production: Detection relies on the Modified Hodge Test.
- Glycopeptide resistance: The vanA gene is tested for using PCR.
- Oxacillin resistance: The cefoxitin disk diffusion test can help identify this.
- Penicillin resistance: Often due to beta-lactamase production.
