Suppose that the A1 subunit of CT were deleted in a new strain of bacteria. What would be the expected pathology of individuals infected with this strain?
A. The bacterium would be unable to colonize the intestines, thus individuals exposed to this bacterium would not become symptomatic.
B. The bacterium would colonize the intestines, but the individuals would not experience any symptoms.
C. The bacterium would have a reduced capacity to colonize the intestines, but there would be some diarrhea due to a slight overactivation of CTFR.
D. The bacterium would colonize the intestines, but the individuals would not experience diarrhea caused by constitutive action of CFTR.
