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.
从胆汁中分离出的一株嗜水气单胞菌仅在非选择性培养基上生长时氧化酶呈阳性。该分离株在革兰氏阴性选择性和/或鉴别培养基上生长时氧化酶呈阴性。建议对革兰氏阴性杆菌进行氧化酶试验时,应在非选择性培养基上生长的菌落上进行,以确保结果有效。
