📖 1. Introduction to Antibiotics

🔑 Key Concepts & Definitions

• Antibiotics: Substances produced by microorganisms or synthetically designed agents that specifically inhibit or kill bacteria, used to treat bacterial infections.
• Antimicrobial agents: Compounds that act against a broad range of microorganisms, including bacteria, fungi, viruses, and protozoa.
• Bactericidal: Antibiotics that kill bacteria directly, leading to bacterial cell death.
• Bacteriostatic: Antibiotics that inhibit bacterial growth and reproduction, relying on the immune system to eliminate bacteria.
• Spectrum of activity: The range of bacteria (broad-spectrum vs. narrow-spectrum) that an antibiotic can effectively target.
• Mechanism of action: The specific bacterial process or structure that an antibiotic targets (e.g., cell wall synthesis, protein synthesis).
