The correct answer is D.Pseudomonas aeruginosa causes malignant otitis externa, which is a severe
necrotizing infection of the external ear canal. Infection tends to spread to the mastoid bone, temporal bone,
sigmoid sinus, base of the skull, meninges, and brain. Patients at increased risk include the elderly, those with
diabetes, and the immunocompromised. Pseudomonas is also associated with many other clinical syndromes,
including infection following traumatic wounds to the feet in persons wearing sneakers or rubber-soled shoes,
since the organism can be cultured from the shoes.
