Leifsonia aquatica is an aquatic coryneform rod that is capable of forming biofilms in environmental water sources. It has rarely been associated with human infections and its pathogenicity and clinical significance are uncertain. We describe a case of catheter-related bloodstream infection in a haemodialysis patient. The isolate grew on conventional media as a yellow-pigmented colony, but identification required molecular methods. Although the strain displayed reduced sensitivity to vancomycin, the clinical outcome was favourable after catheter removal and intravenous treatment with this antibiotic. Our report gives further evidence of the capability of this aquatic bacterium to cause human infection.
水生棒杆菌是一种水生棒状杆菌,能够在环境水源中形成生物膜。它很少与人类感染有关,其致病性和临床意义尚不确定。我们描述了一例血液透析患者与导管相关的血流感染。该分离株在常规培养基上生长为黄色色素菌落,但鉴定需要分子方法。尽管该菌株对万古霉素的敏感性降低,但在导管去除和静脉内使用这种抗生素治疗后,临床结果良好。我们的报告进一步证明了这种水生细菌引起人类感染的能力。
