Which of the following bacteria cause the intracellular accumulation of high levels of C -AMP?
After reaching small bowel vibrio cholerae produces cholera toxin, which consists of A and B subunit. The B subunit binds to GM1 ganglioside, making possible the delivery of the A subunit to its cytosolic target. The ultimate result is the prolonged activation of C-AMP resulting in intracellular accumulation of high levels of cyclic AMP.
