Comamonas species are rarely associated with human infections. Recent reports found that Comamonas kerstersii was associated with severe diseases such as abdominal infection and bacteremia. However, Comamonas kerstersii may be confused with Comamonas testosteroni using the automatic bacterial identification systems currently available. An 8-year-old boy who had a right iliac fossa pain and classic migration of pain at the temperature of 38.9°C. The positive strain of aerobic and anaerobic bottles of blood cultures was identified. The patient was diagnosed as acute peritonitis and perforated appendix with abdominal abscess. The bacterium was identified by routine methods, MALDI-TOF-MS. The patient was treated with exploratory laparotomy, appendectomy, tube drainage, and prescribing antibiotic treatment. The patient was discharged with complete recovery. The organisms were confirmed as Comamonas kerstersii by MALDI-TOFMS and a combination of the other results. Our findings suggest that Comamonas kerstersii infection occurs most often in association with perforated appendix and bacteremia. We presume that Comamonas kerstersii is an opportunistic pathogen or commensal with the digestive tract and appendix bacteria.
产碱菌属物种很少与人类感染有关。最近的报告发现，嗜麦芽窄食单胞菌与严重疾病如腹部感染和菌血症有关。然而，目前可用的自动细菌鉴定系统可能会将产碱假单胞菌与嗜麦芽窄食单胞菌混淆。一名 8 岁男孩出现右髂窝疼痛和典型的疼痛转移，体温为 38.9°C。有氧和厌氧瓶血液培养的阳性菌株被鉴定出来。患者被诊断为急性腹膜炎和阑尾穿孔伴腹腔脓肿。通过常规方法、MALDI-TOF-MS 鉴定细菌。患者接受了剖腹探查术、阑尾切除术、管引流和开处方抗生素治疗。患者完全康复出院。通过 MALDI-TOFMS 和其他结果的组合，确认该生物体为产碱假单胞菌。我们的研究结果表明，嗜麦芽窄食单胞菌感染最常与阑尾穿孔和菌血症有关。我们推测嗜麦芽窄食单胞菌是一种机会性病原体或与消化道和阑尾细菌共生。
