Surviving in a Microbial World - Bacterial pathogenesis

3 important questions on Surviving in a Microbial World - Bacterial pathogenesis

What are the steps of bacterial pathogenesis

  1. Bacterial exposure: source of disease
  2. Colonization: passing barriers and infecting organism
  3. Immune evasion: resisting immune response and proliferation
  4. Infection

How do bacteria evade the immune system?

Virulence factors: Bacteria produce toxins, enzymes, and other factors to directly damage host cells and/or modify the immune synapse.

How do bacteria affect their microenvironment?

Metabolic tuning: Bacteria can create tolerance, limit clearance, and promote their own survival, influencing disease outcomes.
