Table 4. SOURCES AND ACTIVITIES OF BACTERIAL TOXINS

NAME OF TOXIN	BACTERIUM INVOLVED	ACTIVITY
Anthrax toxin (EF)	Bacillus anthracis	Edema Factor (EF) is an adenylate cyclase that causes increased levels in intracellular cyclic AMP in phagocytes and formation of ion-permeable pores in membranes (hemolysis)
Adenylate cyclase toxin	Bordetella pertussis	Acts locally to increase levels of cyclic AMP in phagocytes and formation of ion-permeable pores in membranes (hemolysis)
Cholera enterotoxin	Vibrio cholerae	ADP ribosylation of G proteins stimulates adenylate cyclase and increases cAMP in cells of the GI tract, causing secretion of water and electrolytes
E. coli LT toxin	Escherichia coli	Similar to cholera toxin
Shiga toxin	Shigella dysenteriae	Enzymatically cleaves rRNA resulting in inhibition of protein synthesis in susceptible cells
Botulinum toxin	Clostridium botulinum	Zn++ dependent protease that inhibits neurotransmission at neuromuscular synapses resulting in flaccid paralysis
Tetanus toxin	Clostridium tetani	Zn++ dependent protease that inhibits neurotransmission at inhibitory synapses resulting in spastic paralysis
Diphtheria toxin	Corynebacterium diphtheriae	ADP ribosylation of elongation factor 2 leads to inhibition of protein synthesis in target cells
Pertussis toxin	Bordetella pertussis	ADP ribosylation of G proteins blocks inhibition of adenylate cyclase in susceptible cells
Staphylococcus enterotoxins*	Staphylococcus aureus	Massive activation of the immune system, including lymphocytes and macrophages, leads to emesis (vomiting)
Toxic shock syndrome toxin (TSST-1)*	Staphylococcus aureus	Acts on the vascular system causing inflammation, fever and shock
Pyrogenic exotoxins (SPE) e.g. Erythrogenic toxin (scarlet fever toxin)*	Streptococcus pyogenes	Causes localized erythematous reactions
