<i>Comamonas testosteroni</i> meningitis in a patient with recurrent cholesteatoma

Abstract

Comamonas testosteroni, a lesser-known member of the genus, has shown little apparent capacity for causing infections in humans. We here present a case of purulent meningitis due to C. testosteroni, which occurred in a patient who had recurrent cholesteatoma. Ceftriaxone treatment was not effective in this patient even though in vitro the bacteria were susceptible to the drug. The patient responded well to meropenem therapy.
