Characteristic of Bacillus cereus food poisoning is?
**Core Concept**
Bacillus cereus is a gram-positive, spore-forming bacterium that can cause food poisoning through two distinct syndromes: the diarrheal type and the emetic type. The diarrheal type is characterized by the production of diarrheal toxins, while the emetic type is associated with the production of a toxin that induces vomiting.
**Why the Correct Answer is Right**
The emetic type of Bacillus cereus food poisoning is caused by the production of a heat-stable toxin that is similar to the Staphylococcal enterotoxin. This toxin is produced during the growth of the bacteria in food, particularly in rice, and is not inactivated by cooking or reheating. The toxin acts on the emetic center in the brain, leading to vomiting and abdominal cramps.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because Bacillus cereus food poisoning is not typically associated with the production of a toxin that causes hemolysis or coagulopathy.
**Option B:** Incorrect because Bacillus cereus is not typically associated with the production of a toxin that causes hemolysis or coagulopathy.
**Option C:** Incorrect because Bacillus cereus food poisoning is not typically associated with the production of a toxin that causes hemolysis or coagulopathy.
**Clinical Pearl / High-Yield Fact**
To prevent Bacillus cereus food poisoning, it is essential to handle and store food properly, particularly cooked rice, which can be a common source of the bacteria. It is also crucial to note that Bacillus cereus can produce spores that are highly resistant to heat and drying, making it challenging to eradicate the bacteria from contaminated food.
**Correct Answer: C. The emetic type of Bacillus cereus food poisoning is associated with the production of a toxin that induces vomiting.**
