Turicella otitidis is a newly described coryneform bacterium isolated from middle ear fluids. We report here on the diagnosis of a strain isolated from otorrhea. The API Coryne system (bioMérieux, Marcy I'Etoile, France) used alone failed to differentiate T. otitidis, Corynebacterium afermentans, and Corynebacterium auris (ANF group). Biochemical tests such as DNase, enzymatic reactions (API ZYM; bioMérieux), and carbon substrate assimilation tests (Biotype 100; bioMérieux) allow presumptive identification. However, only chemotaxonomy and molecular biology can achieve unequivocal differentiation among these three species.
耳氏图里西拉菌是一种新描述的棒状杆菌,从中耳液中分离得到。我们在此报告从耳漏中分离出的一株该菌的诊断情况。单独使用API棒状杆菌系统(法国马西伊图瓦勒生物梅里埃公司)无法区分耳氏图里西拉菌、非发酵棒状杆菌和耳棒状杆菌(ANF组)。诸如脱氧核糖核酸酶、酶促反应(API ZYM;生物梅里埃公司)和碳源同化试验(Biotype 100;生物梅里埃公司)等生化试验可进行初步鉴定。然而,只有化学分类学和分子生物学才能明确区分这三个菌种。
