A Gram-negative bacillus isolated from the blood of a leukaemic patient with septicaemia was identified on the basis of common tests as Escherichia coli. However, the organism's antibiogram was atypical of E. coli and led to its re-examination and correct identification as Aeromonas hydrophila. A. hydrophila is sensitive to chloramphenicol and tetracycline, characteristics useful in differentiation from E. coli. A simple test differentiating this organism from the Enterobacteriaceae is the oxidase test. A. hydrophila is oxidase positive.
从一名患有败血症的白血病患者血液中分离出的革兰氏阴性杆菌,经常规检测鉴定为大肠杆菌。然而,该菌的抗菌谱并非典型的大肠杆菌抗菌谱,这促使对其进行重新检测,并最终正确鉴定为嗜水气单胞菌。嗜水气单胞菌对氯霉素和四环素敏感,这一特性有助于将其与大肠杆菌区分开来。一种用于区分该菌与肠杆菌科细菌的简单检测方法是氧化酶试验。嗜水气单胞菌氧化酶试验呈阳性。
