Which of the following is a possible serious infection associated with Salmonella infection?

• A. Meningitis
• B. Pneumonia
• C. Diabetes
• D. Rheumatoid arthritis

Answer: (A)

Salmonella infections can be more than just gastroenteritis; in some cases the bacteria enter the bloodstream and spread to other parts of the body. When the bacteria seed the meninges, they can cause meningitis. This invasive, hematogenous spread is why meningitis is a recognized serious complication of Salmonella infection, especially in vulnerable groups such as newborns, the elderly, and individuals with weakened immune systems or malnutrition. The other options aren’t infections caused by Salmonella: diabetes and rheumatoid arthritis are chronic conditions, not infectious diseases, and while pneumonia can rarely occur with invasive Salmonella, meningitis is the classic serious complication to recognize in this context.
