Micro 14: Mechanisms of Bacterial Pathogenesis
This episode examines how bacteria convert structure and genetic capacity into clinical disease. Drawing from Murray’s chapter, it explores the core mechanisms of bacterial pathogenesis: adherence to host tissues, invasion, toxin production, immune evasion, and persistence.
Rather than treating virulence as a single trait, the episode presents it as a coordinated sequence of events. Adhesins allow attachment. Invasins breach barriers. Toxins disrupt physiology. Capsules and antigenic variation evade immune recognition. Biofilms create protected communities resistant to both immunity and…
