Unusual Corynebacterium mucifaciens isolated from ear and nasal specimens.
OBJECTIVE
Corynebacterium mucifaciens was first proposed as a novel Corynebacterium species in 1997. This report describes our experience with the unexpectedly frequent isolation of C mucifaciens.


METHODS
By using agar supplemented with several antibiotics, microbiological studies were performed on specimens collected from the ear and nose.


METHODS
A primary and secondary referral hospital.


RESULTS
The organisms grew slowly. Five strains of C mucifaciens were found in specimens of middle ear effusion (MEE) from patients with otitis media with effusion (OME), and four strains were isolated from the nasal polyps and nasal discharge of patients with chronic sinusitis (CRS).


CONCLUSIONS
C mucifaciens was isolated from nine otorhinological specimens.


CONCLUSIONS
This is the first report about the isolation of C mucifaciens from MEE, nasal polyps, and nasal discharge. Although its pathogenetic role is unknown, the characteristics of this microorganism might make it a potential cause of OME and/or CRS, so further studies are necessary.
