|The famous B cereus joke - Why so serious? Let's put a smile on that face *Joker laugh*|
B cereus produces two patterns of foodborne disease.
One is characterized by diarrhea and abdominal pain, 8-16 hours after ingestion of contaminated food like vegetables. It is caused by a heat labile enterotoxin. B cereus is not found in large numbers in fecal specimens in this pattern of food poisoning.
The second type is characterized with the nausea and vomiting, 1-5 hours after ingestion of contaminated rice. (Usually fried or reheated rice in Chinese restaurants)
Interesting fact: B cereus is not killed by steaming.
It is caused by a heat - stable exotoxin. B cereus is present in large numbers in the fecal samples as well as the cooked rice.
Another interesting fact: The emetic toxin was produced only when B cereus was grown in rice but not in other media!
Eggs increases growth of B cereus, so it's not surprising that B cereus is isolated on a special media called mannitol-egg yolk-phenol red-polymxin agar.
(Dat name! T_T "MYPA agar" is the short nickname, yaay! )
