Section 5: Pathogenesis & Host Defenses

Slide 12: Steps in Microbial Pathogenesis

1. Entry – Skin, respiratory, GI, GU, vertical.
2. Adhesion – Adhesins binding to host receptors.
3. Evasion of defenses – Capsule, antigenic variation, intracellular survival.
4. Damage – Direct (toxins) or indirect (inflammation).
5. Transmission – Shedding to new host.

: Effective slides typically highlight life cycles and the specific diseases caused by key microorganisms, aiding in rapid recall. Content Coverage: The Ultimate Guide to Medical Microbiology Lecture Notes

Limitations: Asymptomatic carriers, unculturable organisms (e.g., Treponema pallidum), viral diseases.

Molecular Koch’s postulates: Link specific gene to virulence (e.g., toxin gene knockout → attenuated).

Slide 16: Mechanisms of Antibiotic Resistance

• Enzymatic destruction: β-lactamases (e.g., ESBL, KPC carbapenemase).
• Altered target: MRSA (PBP2a → methicillin resistance).
• Reduced uptake: Gram-negative porin mutations.
• Efflux pumps: Tetracycline, macrolide resistance.
• Biofilms: Pseudomonas in CF lungs.

• “Don’t confuse: Group B Strep (GBS, S. agalactiae) with Group A Strep (GAS, S. pyogenes). GBS causes neonatal sepsis; GAS causes pharyngitis & rheumatic fever.”
