||||
| IgA protease | show 🗑
|

| show | S. pneumoniae, H. influenzae, Neisseria
🗑
|
||||
| show | Helps to prevent phagocytosis. Is secreted by streptococcal species.

🗑
|
||||

🗑
|
||||
| show | S. Aureus, S. pyogenes
🗑
|
||||
| Superantigen of S. aureus is called ____ and produces ___ with the symptoms of ____,____, ___. | show 🗑
|
||||
| show | Food poisoning and exfoliatin (scalded skin syndrome)

|
||||
| show | TSST-1 (toxic shock syndrome) (fever, rash, shock)
🗑
|
||||
| show | Food poisoning and exfoliatin (scalded skin syndrome)
🗑
|
||||
| show | Scarlet fever-erythrogenic toxin; causes toxic shock syndrome)
🗑
|
||||
| show | Interfere with host cell function. B= binds to receptor on surface of host cell, enabling endocytosis. A (active) then attaches an ADP-ribosyl to a host cell protein, altering protein function.
🗑
|
||||
| show | Corynebacterium diptheriae, Vibrio cholerae, E. Coli, Bordetella pertussis.
🗑
|
||||
| C. diptheriae produces an ___ type of exotoxin. It works by ___. It produces ____. | show 🗑
|

|
||||
| E. coli produces an ___ type of exotoxin. It works by ____. Produces ____. | show 🗑
|
||||
| show | ADP-ribosylating toxin. It works by increasing cAMP by inhibiting Gi. Causes whooping caugh, inhibits chemokine receptor, causing lymphocytosis.
🗑
|
