A simple, rapid, semiquantitative slide catalase test useful for differentiating members of the family Enterobacteriaceae is described. Judging by the time required for appearance of oxygen bubbles in 3% hydrogen peroxide, the immediate catalase reactors were Yersinia, Serratia, Proteus, Morganella, Providencia, Cedecea, and Hafnia spp. The delayed catalase reactors were Escherichia, Shigella, Klebsiella, Enterobacter, Salmonella, Citrobacter, Edwardsiella, Kluyvera, and Tatumella spp. This information is especially useful for differentiating Serratia from Enterobacter spp. and Yersinia from Escherichia and Shigella spp.
本文描述了一种简单、快速的半定量玻片过氧化氢酶试验，可用于区分肠杆菌科的成员。根据在3%过氧化氢中出现氧气泡所需的时间判断，立即产生过氧化氢酶反应的是耶尔森菌属、沙雷菌属、变形杆菌属、摩根菌属、普罗威登斯菌属、西地西菌属和哈夫尼亚菌属。延迟产生过氧化氢酶反应的是大肠埃希菌、志贺菌属、克雷伯菌属、肠杆菌属、沙门菌属、柠檬酸杆菌属、爱德华菌属、克吕韦菌属和塔图姆菌属。这些信息对于区分沙雷菌属与肠杆菌属，以及耶尔森菌属与大肠埃希菌和志贺菌属特别有用。
