(From external source) Which bacteria produce enterotoxins that cause watery diarrhea in cases of bacterial gastroenteritis?

Salmonella and Campylobacter.

Shigella and Yersinia.

Vibrio cholerae and Clostridium perfringens.

E. coli and C. diff.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Salmonella and Campylobacter are known to cause bacterial gastroenteritis, but they typically do not produce enterotoxins that specifically cause watery diarrhea. Instead, they often cause more inflammatory types of diarrhea.

Choice B rationale:

Shigella and Yersinia can also cause bacterial gastroenteritis, but their mechanisms of causing diarrhea are different from enterotoxin production. Shigella is known to cause bloody diarrhea, while Yersinia can lead to abdominal pain and fever.

Choice C rationale:

Vibrio cholerae produces the cholera toxin, which leads to watery diarrhea by increasing chloride secretion and inhibiting sodium absorption in the intestines. Clostridium perfringens can produce enterotoxins that lead to watery diarrhea and abdominal cramps.

Choice D rationale:

While E. coli can cause gastroenteritis, it usually produces Shiga toxins that lead to bloody diarrhea (as seen in E. coli O157:H7), or it may cause inflammation and not typically result in watery diarrhea. C. difficile is known for causing antibiotic-associated diarrhea and colitis, but it's not primarily associated with watery diarrhea.

Choice C rationale:

Washing hands with soap and water before meals is essential to remove potential pathogens and prevent transmission.

Choice D rationale:

While keeping children indoors during the rainy season can reduce exposure to certain infections, it is not a direct measure to prevent gastroenteritis.

A. Vomiting and fever. B. Abdominal pain and cramps. C. Chronic diarrhea with bloody stools. D. Dehydration and electrolyte imbalance.

Correct Answer is B

Explanation

Choice A rationale:

Vomiting and fever can be symptoms of gastroenteritis, but they are not the primary characteristic feature. Abdominal pain and cramps are more indicative of gastroenteritis.

Choice B rationale:

Abdominal pain and cramps are indeed the primary characteristic feature of gastroenteritis. Gastroenteritis is an inflammation of the stomach and intestines, often leading to symptoms such as abdominal discomfort, pain, and cramps.

Choice C rationale:

Chronic diarrhea with bloody stools is not the primary characteristic feature of gastroenteritis. Bloody stools are more commonly associated with conditions like inflammatory bowel disease.

Choice D rationale:

Dehydration and electrolyte imbalance are common complications of gastroenteritis due to the loss of fluids through vomiting and diarrhea. However, they are not the primary characteristic feature of the condition.
