Septic arthritis is a rare infection usually involving the knee or hip but can infrequently affect less obvious joints such as the pubic symphysis.Risk factors for septic arthritis include joint repair or replacement surgery, systemic infection, intravenous recreational drug use, and alcoholism.We present the case of a 48-year-old man with a final diagnosis of septic arthritis of the pubic symphysis who had no risk factors besides alcoholism. The presentation was unusual in that the patient was afebrile,and the infection seemed to be spontaneous. The infecting pathogen was identified as Streptococcus anginosus or S constellatus, both being normal intestinal flora. Infection by either bacterium is rare in septic arthritis.
化脓性关节炎是一种罕见的感染，通常累及膝关节或髋关节，但很少会影响不太明显的关节，如耻骨联合。化脓性关节炎的危险因素包括关节修复或置换手术、全身感染、静脉注射毒品及酗酒。我们报告一例48岁男性，最终诊断为耻骨联合化脓性关节炎，除酗酒外无其他危险因素。该病例表现不寻常，患者无发热，感染似乎是自发的。感染病原体鉴定为咽峡炎链球菌或星座链球菌，二者均为正常肠道菌群。这两种细菌引起的感染在化脓性关节炎中均罕见。
