Exotoxins Flashcards
Type II secretory apparatus
Structure is closely related to flagellum
Very tip of needle is able to interact and puncture the host cell
Factors affecting growth rate
Medium composition
Temperature
Oxygen
Peptidoglycan synthesis
Glycan is synthesized in bacterial cytoplasm and transferred across inner membrane and ligated into pre-existing strands
These synthetic proteins are targeted and inhibited by penicillin
Siderophores
Important for pathogenesis
Bacteria synthesizes it, sends it out to go bind Fe, the complex gets taken up by bacteria
Important virulence factors, can be coded on plasmids and shared between bacteria
Respiration
On inner membrane
Enzymes to clear O2 toxins; peroxidases, superoxide dismutases
