Medical Microbiology: Lecture Notes (Article)

Overview

Medical microbiology studies microorganisms (bacteria, viruses, fungi, parasites, prions) that cause disease in humans, including their taxonomy, structure, physiology, pathogenic mechanisms, host responses, diagnosis, treatment, and prevention.

9. Antimicrobial Agents & Resistance

• Antibacterials: Cell wall inhibitors (beta-lactams, vancomycin), protein synthesis inhibitors (macrolides, aminoglycosides, tetracyclines), DNA/RNA synthesis inhibitors (fluoroquinolones), metabolic pathway inhibitors (sulfonamides).
• Antivirals: Target replication enzymes (e.g., reverse transcriptase inhibitors, neuraminidase inhibitors), protease inhibitors.
• Antifungals: Azoles, echinocandins, amphotericin B.
• Resistance mechanisms: Enzymatic degradation (beta-lactamases), target modification, efflux pumps, permeability changes.
• Prevention of resistance: Stewardship, appropriate dosing/duration, infection control.
