Micro 12: Bacterial Classification, Structure, and Replication

Clinical Deep Dives · Feb 15, 2026 · 43m

This episode marks the formal beginning of bacteriology. Drawing from Murray’s chapter, it introduces bacteria not as clinical labels, but as structured biological systems defined by their morphology, cell wall composition, genetic organisation, and modes of replication.

The episode explores Gram-positive and Gram-negative architecture, cell membranes, peptidoglycan layers, outer membranes, endotoxin, flagella, pili, and capsules. Classification is framed as a reflection of structure and behaviour rather than mere naming convention. Binary fission, growth kinetics, and environmental…
