3. Pathogenesis & Virulence Factors

• Adhesins: Pili, surface proteins.
• Invasins: Enzymes degrading host tissues (collagenase, hyaluronidase).
• Toxins: Exotoxins (protein, often heat-labile, e.g., diphtheria toxin, cholera toxin), endotoxin (LPS — causes fever, septic shock).
• Immune evasion: Capsule, antigenic variation, intracellular survival.

Module 1: General Bacteriology (The Foundation)

• Structure: Difference between Gram (+) and Gram (-) cell walls (Peptidoglycan, LPS, Porins).
• Staining: Step-by-step Gram stain, Acid-fast (Ziehl-Neelsen), and Spore staining.
• Growth: Aerobes, Anaerobes, Capnophiles; Binary fission generation times.
• Sterilization: Autoclave (121°C at 15 psi), Pasteurization, and filtration.
