摘要 目的探讨Robinsoniella peoriensis(R.peoriensis)与艰难梭菌(Clostridium difficile)的鉴别诊断。方法2016年12月广州军区广州总医院检验科从1例疑似抗生素相关性腹泻患者的粪便标本中分离到了1株R.peoriensis,采用实验室检测方法与本实验室收集的艰难梭菌(Clostridium difficile)进行鉴别诊断。对分离株进行革兰染色、生长特性、形态特点、生化特征、酶免疫法检测、基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)以及16S rRNA序列分析。结果R.peoriensis是一种革兰阳性厌氧芽孢短杆菌,MALDI-TOF MS与谷氨酸脱氢酶(GDH)均不能将R.peoriensis与艰难梭菌区别开,16 srRNA测序是唯一能准确鉴定R.peoriensis的方法。结论传统的鉴定系统尚不能识别或错误识别R.peoriensis,易与艰难梭菌产生混淆,干扰艰难梭菌相关性腹泻的诊断。(中华检验医学杂志,2018, 41:73-76)
