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.

Bacteremia due to Comamonas species possibly associated with exposure to tropical fish.  
[My paper] Marcus D Smith , Jeremy D Gradon  
Comamonas species are environmental gram-negative rods that grow forming pink-pigmented colonies. Despite their
common occurrence in nature, they rarely cause human infection. We present a case of Comamonas bacteremia that
we think may have been related to tropical fish exposure. The patient was treated successfully with levofloxacin.
