Bacillus cereus has been implicated as the etiologic agent in which condition?

• A. Food poisoning
• B. Impetigo
• C. Pelvic inflammatory disease
• D. Toxic shock syndrome

Answer: (A)

Bacillus cereus is classically linked to a foodborne illness due to its ability to form toxins in food or after ingestion, leading to two distinct syndromes: a rapid-onset vomiting form from a preformed emetic toxin in starchy foods (often rice) and a diarrheal form from enterotoxins produced in the gut. This makes it a well-known cause of food poisoning, especially when prepared foods are kept warm for too long. It is not a typical cause of impetigo (skin infection), pelvic inflammatory disease (gonorrhea/chlamydia), or toxic shock syndrome (staph or strep toxin-mediated), so the condition most accurately associated with Bacillus cereus is food poisoning.
