Which of the following is NOT one of the life-threatening complications of Salmonellosis listed?

• A. Bloodstream infection
• B. Brain infection
• C. Joint infection
• D. Lung infection

Answer: (D)

When evaluating invasive Salmonellosis, the most dangerous complications come from the bacteria spreading through the bloodstream and seeding other body sites. The classic life-threatening issues are bloodstream infection, which can lead to sepsis; brain infection such as meningitis; and joint infection like septic arthritis. These reflect Salmonella’s ability to disseminate beyond the gut and cause serious systemic disease, especially in vulnerable people.

Lung infection is not typically listed among these life-threatening invasive complications. While Salmonella can occasionally be associated with pneumonia, it is not a common or standard part of the severe invasive complication set described in practice guides. Therefore, the lung infection option is not considered one of the classic life-threatening complications of Salmonellosis.
