After closed reduction and casting of a tibial fracture in a 69-year-old diabetic man, a gangrenous lesion developed under the cast. Cultures of debrided tissue revealed multiple bacteria, including Bacillus sp, plus two fungi, Fusarium sp and a zygomycete identified as Cunninghamella bertholletiae. Large nonseptate hyphae in thrombosed blood vessels suggested that C bertholletiae played a major role in the development of the infection. Recovery of organisms from our patient's wound and from the cast padding suggests that the wound infection was acquired from nonsterile dressings.
一名69岁的糖尿病男性胫骨骨折经闭合复位和石膏固定后，石膏下出现坏疽性病变。清创组织培养显示有多种细菌，包括芽孢杆菌属，还有两种真菌，镰刀菌属和一种被鉴定为柏氏小克银汉霉的接合菌。血栓形成血管中的粗大无隔菌丝表明柏氏小克银汉霉在感染发展中起主要作用。从我们患者的伤口和石膏衬垫中发现微生物表明伤口感染是由非无菌敷料引起的。
