Questions and Answers

Match the antimicrobial resistance type with its respective test or gene:

MRSA = mecA gene produces altered PBP2a VRSA = Modified Hodge Test ESBL = Test with clavulanic acid only Clindamycin = Etest

Match the antimicrobial resistance type with its diagnostic method:

Carbapenemase = Modified Hodge Test Glycopeptides = van A PCR Oxacillin = Cefoxitin Disk test Penicillin = Etest

Match the gene associated with antibiotic resistance:

Clindamycin = Erm gene VRSA = mecA gene ESBL = B-lactamase Oxacillin = Cefoxitin

Study Notes

Antimicrobial Resistance Testing

  • MRSA (Methicillin-resistant Staphylococcus aureus): Characterized by the mecA gene, which alters penicillin-binding protein 2a (PBP2a).

  • VRSA (Vancomycin-resistant Staphylococcus aureus): Diagnosis involves using an Etest.

  • ESBL (Extended-spectrum β-lactamases): Testing includes performing tests with and without clavulanic acid.

  • Clindamycin Resistance: The Erm gene is associated with resistance.

  • Carbapenemase Resistance: Detection uses a Modified Hodge Test.

  • Glycopeptide Resistance (e.g., Vancomycin): vanA gene presence is confirmed via PCR.

  • Oxacillin Resistance: Detects using a Cefoxitin disk diffusion test.

  • Penicillin Resistance: Linked to β-lactamase production.
