Paludibacterium purpuratum was first reported as a Gram stain-negative, curved, rod-shaped bacterium isolated from a wetland soil in 2016. We report the first case in the world, to our knowledge, of pyogenic spondylitis caused by P. purpuratum. The patient, a 78-year-old man, came to our hospital complaining chiefly of fever and pain in the left knee. He did not complain of low back pain at the time of examination, although increased low back pain was observed for the first time after admission. Magnetic resonance imaging of the lumbar spine and percutaneous needle biopsy at the L2/L3 disc level were performed, and pyogenic spondylitis was diagnosed. A curved, Gram stain-negative rod was detected in the blood culture obtained at admission that was identified as P. purpuratum by 16S rDNA gene analysis.
紫单胞菌于 2016 年首次被报道为一种革兰氏染色阴性、弯曲、杆状细菌，从湿地土壤中分离得到。我们报告了世界上首例由紫单胞菌引起的化脓性脊柱炎。患者为 78 岁男性，因发热和左膝关节疼痛为主诉就诊。入院时虽未诉腰痛，但入院后首次出现腰痛加重。行腰椎磁共振成像和 L2/L3 椎间盘水平经皮穿刺活检，诊断为化脓性脊柱炎。入院时血培养中检出一种弯曲的革兰氏染色阴性杆状菌，经 16S rDNA 基因分析鉴定为紫单胞菌。
