嗜麦芽窄食单胞菌致皮肤感染的研究进展

Skin infections eansed by Stenotrophomnas maltophilia

嗜麦芽窄食单胞菌是自然界和医院环境广泛存在的非发酵型需氧的革兰阴性杆菌，目前已成为重要的机会致病菌，好发于免疫力低下的人群。该菌可引起多个系统感染，包括皮肤黏膜感染，多为血液播散和皮肤黏膜直接接触感染。临床表现多样，包括：原发性蜂窝织炎、转移性结节或蜂窝织炎、坏疽性深脓疱病和皮肤溃疡等。该菌的致病性已引起广泛的关注。

Stenotrophonmas maltophilia is a nonfermentative, aerobic gram-negative bacillus that is widely distributed in natural and human-made environment. Now it is recognized as an important opportunistic pathogen which primarily infects immunosuppressive population. Multiple organs can be involved in this infection. Cutaneous mucosa infection with S.maltophilia usually results fi＇om blood dissemination and direct contact. Clinical manifestations of S.maltophilia infection are various, include primary cellulites, metastatic nodules or cellulites, ecthyma gangrenosum, cutaneous ulceration, etc. General attention has been attracted to the pathogenicity of this microorganism.
