Meningitis due to Aeromonas hydrophila

A case of meningitis caused by Aeromonas hydrophila is reported. The infection complicated an otherwise successful frontotemporal craniotomy. Survey of the literature revealed that human infections due to this organism are relatively uncommon, and its causal relationship in meningitis has not been previously reported. A. hydrophila is known to cause bacteremia in patients under treatment with immunosuppresive agents. We report meningitis with bacteremia, caused by this organism, in an immunologically competent host.
