memorize

 

Name three physiological roles ascribed to bacterial capsules?: Resist desiccation; Nutrient storage; Adhesion; Resistance to phagocytosis; Waste dumping ground
What is the relationship between pathogenesis and capsules of bacterial pathogens?: The capsule is more resistant to phagocytosis and assists in virulence by helping adhere to the host cell wall
Give the name of one aerobic, anaerobic and facultative anaerobe bacteria: B. subtilis (aerobic); C. tetanomorphum (anaerobic); E. coli, S. aureus (facultative anaerobe)
