Q.54
Mahesh was admitted to the hospital with severe diarrhoea, abdominal cramps and fever. The doctor diagnosed
the condition as food infection.
Which of the following microorganism may have been likely the cause of this infection?
- Etiology of Salmonellosis Food Infection:
- Clinical Manifestations: Acute onset of watery diarrhea, severe abdominal cramps, nausea, and high fever starting 12 to 72 hours following ingestion.
- Food Infection vs Intoxication:
- Salmonella enterica causes a true food infection, invading the epithelial lining of the small intestine and colon and causing inflammatory enteritis.
- In contrast, Staphylococcus aureus, Clostridium botulinum, and Bacillus cereus primarily cause food intoxications mediated by preformed exotoxins (enterotoxin, neurotoxin), which typically produce rapid vomiting within 1–6 hours without sustained high fever.
- Conclusion: Salmonella (Option 4).
Correct option: (4) Salmonella
