Identification of Turicella otitidis isolated from a patient with otorrhea associated with surgery: differentiation from Corynebacterium afermentans and Corynebacterium auris

Abstract

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.
