摘要 目的对从SLE患者血液分离的1株口腔纤毛菌进行鉴定及药敏试验。方法用生化鉴定ANC卡及手工方法进行综合鉴定;采用16S r DNA基因测序复核鉴定;K-B法检测菌株药物敏感性。结果该菌为厌氧、兼性微需氧的革兰阴性长杆菌。ANC卡鉴定为死亡梭杆菌(鉴定率88%),结合鉴定卡部分生化反应、生长试验、触酶试验、氧化酶试验及菌落形态特征鉴定为口腔纤毛菌。16S r DNA基因序列显示该菌与口腔纤毛菌的相似度最高,为99%。该菌除对万古霉素及庆大霉素抑菌圈直径小于10 mm外,对其他检测药物抑菌圈直径均大于20 mm。结论该血培养菌为口腔纤毛菌,16S r DNA基因序列分析是少见菌鉴定的有效工具。
