Question

multiple choice question which infection is associated with elderly patients taking antibiotics for a prolonged period of time? ∘ clostridium difficile ∘ influenza ∘ methicillin - resistant staphylococcus aureus ∘ human immunodeficiency virus

Explanation:

Prolonged antibiotic use, especially in the elderly, can disrupt the normal gut microbiota, leading to overgrowth of Clostridium difficile (C. diff). This bacterium causes infections like diarrhea and colitis. Influenza is a viral respiratory infection, MRSA is often associated with skin infections and hospital - acquired infections (not directly linked to prolonged antibiotic use in the same way as C. diff), and HIV is a virus transmitted through specific routes (not related to antibiotic use). So the infection associated with elderly patients on prolonged antibiotics is Clostridium difficile.

Answer:

A. Clostridium difficile
