Bacillus cereus

A ubiquitous, aerobic spore-forming, gram-positive non-anthrax bacillus.
 
Epidemiology
B cereus causes foodborne outbreaks of gastroenteritis in Europe, but not in the US. Of the two clinical forms of disease, the diarrhoeal form is more common and has a 24-hour incubation period; the emetic (vomiting) form has a shorter (1–6-hour) incubation period.
 
Clinical findings
• Diarrhoeal form—Epidemic gastroenteritis, diarrhoea.
• Emetic form—Watery diarrhoea, abdominal cramping, fever.

Management
Because symptoms are mild, self-limited and mediated by an enterotoxin, antibiotics are not indicated.
 
Pathogenesis
B cereus is found in uncooked rice; the heat-resistant spores survive boiling, and germinate when uncooked rice is left unrefrigerated. Each type of gastroenteritis is caused by a different enterotoxin.
