A Case of Acute Otitis Media Caused by Providencia stuartii / 대한임상병리학회지

ABSTRACT

Providencia stuartii is occasionally isolated from patients with chronic otitis media, however it has not been reported as a cause of acute otitis media so far. We recently isolated P. stuartii from the pus specimen of right middle ear of a 2-year-old patient with acute otitis media. The patient was admitted because of right-sided otorrhea for 2 weeks. The symptom was not relieved by first-line empirical antibiotics (amoxicillin-clavulanic acid and netilmicin), but it was subsided dramatically with the changed antibiotics (ceftriaxone and amikacin); the isolate was susceptible to these two antibiotics in in vitro susceptibility testing. To our knowledge, this is the first case report of acute otitis media caused by P. stuartii.
