Klebsiella sp. is most commonly associated with septicemia and urinary tract infections.

• A. Pneumonia
• B. Septicemia and urinary tract infections
• C. Meningitis
• D. Skin infections

Answer: (B)

Klebsiella species are frequent culprits in hospital-associated infections and are classically tied to urinary tract infections, often related to catheter use, and to septicemia when the infection spreads to the bloodstream. While they can cause pneumonia, meningitis, or skin infections, those presentations occur less commonly than UTIs and septicemia. So, the combination of septicemia and urinary tract infections best reflects the typical clinical pattern for Klebsiella, making it the most accurate association.
