PURPOSE
To report a very unusual form of coinfection of the extraocular scleral buckle explant by Stenotrophomonas maltophilia and Mycobacterium chelonae.
DESIGN
Interventional case report.
METHODS AND RESULTS
A 61-year-old man had infected buckle after uneventful retinal reattachment surgery. Culture showed coinfection by Stenotrophomonas maltophilia and Mycobacterium chelonae. This concomitance is not random but rather fortified virulence of these otherwise facultative pathogens. Organisms responded to broad-spectrum antibiotics.
CONCLUSIONS
The co-inhabitation of these two low-virulence organisms seems to represent an interesting symbiosis with boosting virulence and resistance to host defense, especially in those immunocompromised.
目的
报告嗜麦芽窄食单胞菌和龟分枝杆菌共同感染眼外巩膜扣带植入物的一种非常罕见的形式。
设计
介入性病例报告。
方法与结果
一名61岁男性在视网膜复位手术顺利后发生扣带感染。培养显示为嗜麦芽窄食单胞菌和龟分枝杆菌共同感染。这种共存并非偶然，而是增强了这些原本为兼性病原体的毒力。这些微生物对广谱抗生素有反应。
结论
这两种低毒力微生物的共同存在似乎代表了一种有趣的共生关系，具有增强的毒力和对宿主防御的抵抗力，尤其是在免疫功能低下的人群中。
