Aureus, S. pyogenesD. Heat labile = stimulates adenylate cyclase. Heat stable = stimulates guanylate cyclase. ADP-ribosylating AB toxin. Both cause watery diarrhea. "Labile like the Air, stable like the Ground".E. Corynebacterium diptheriae, Vibrio cholerae, E. Coli, Bordetella pertussis.F. Edema factor type of adenylate cyclaseG. Food poisoning and exfoliatin (scalded skin syndrome)H. V. cholerae, B. anthracis, E. coli (Heat labile), B. PertussisI. Shiga toxin (also produced by ETEC). Cleaves host cell rRNA (inactivates 60s); also enhances cytokine release. Causes HUS.J. S. aureus. Binds to Fc region of Ig, disrupting opsonization and phagocytosis.K. Blocks acetylcholine; causes anticholinergic symptoms, CNS paralysis, especially cranial nerves. (Spores found in food = floppy baby)L. C. diptheriae produces an ADP-ribosylating A-B toxin.
