Question

Profuse, water diarrhea without mucus or blood would most likely be produced under conditions where bacteria?

A) adhere to but do not penetrate the intestinal mucosa and produce enterotoxin
B) are translocated through the mucosa, cause systemic, infection and upset the salt balance of the blood
C) penetrate the intestinal mucosa, grow in the submucosal area and produce enterotoxin
D) penetrate the intestinal mucosa and grow in the submucosal area
E) grow in the intestinal lumen without attachment to the mucosal cells and produce enterotoxin

Answer 1

Option B), Profuse, watery diarrhea without mucus or blood is likely caused by bacteria adhering to the intestinal mucosa and producing enterotoxin.

Step-by-step explanation:

The most likely condition producing profuse, watery diarrhea without mucus or blood is when bacteria adhere to but do not penetrate the intestinal mucosa and produce enterotoxin. This is commonly seen in cases of gastrointestinal infection by enterotoxigenic E. coli (ETEC) and Vibrio cholerae.

These bacteria release enterotoxins that increase the levels of cyclic AMP (CAMP) in the intestinal cells, leading to the release of ions into the intestinal lumen and a subsequent increase in osmotic pressure, resulting in water entering the lumen and causing profuse diarrhea.
