摘要
１９９３年从两例呼吸道感染病人的痰中分离出两株革兰氏用性小杆菌，经系统鉴定定为嗜麦芽寡女单胞菌（Ｓｔｅｎｏｔｒｏｐｈｏｍｏｎａｓｍａｌｔｏｐｈｉｌｉａ）。因本菌误诊漏检较多，本文就此菌的鉴定经验及鉴定要点进行了观察讨论。在氧化发酵试验中呈迟缓氧化产酸或呈碱性反应，有动力的专性需氧菌，在西蒙氏柠檬酸盐琼脂中不生长，在微量（０．０１％）胨半固体中分解麦芽糖产酸快于葡萄糖，而在油封的麦芽糖管中不产酸。分解乳糖和蔗糖而不便甘露醇产酸，有的菌株半乳糖、木糖也不分解，水解吐温８０、ＤＮＡ和七叶苷。
Two strains of nonfermenting Gram-negative rod isolated from two sputum specimens of two respiratory tract infection patients have been identified as Stenotrophomonas maltophilia( former Xanthomonas maltophilia) . The species is a common bacteria encountered in clinical bacteriology abroad but it is seldom reported in our country probably owing to its puzzling character(of test and oxidase reaction) and the lab workers are not familiar to it.In this study, the authors have evaluated and assessed the experience and the main points in its identification. It is nonsporing Gram-negative aerobic rod; motile with polar flagella; of test is delayed O type or N type; oxidase reaction is weak positive or negative; produce acid from disaccharides,maltose,sucrose,lactose and trehalose; produce acid from maltose stronger than from glucose; lysine decarboxylated; and hydrolyze DNA,esculin and Tween 80. Keeping these points in mind,the identification of the species will be easy.
