Abstract
A strain of Aeromonas hydrophila isolated from bile was oxidase positive only when grown on nonselective media. The isolate was oxidase negative when grown on gram-negative selective and/or differential media. It is proposed that oxidase tests on gram-negative rods be performed on colonies grown on nonselective media to assure valid results.
