Which clinical feature distinguishes shigellosis from cholera?
Solution
Correct Answer: Option B
- The key clinical difference is that shigellosis causes invasive colitis, leading to inflammation and ulceration of the intestinal mucosa, which results in bloody diarrhea (dysentery).
- In contrast, cholera is a non-invasive infection caused by Vibrio cholerae, characterized by the secretion of a toxin that induces profuse watery diarrhea without blood.
Thus, presence of bloody diarrhea distinguishes shigellosis from cholera.
