Otitis media caused by Vibrio cholerae in a child: a case report and literature review

A previously healthy 12-year-old boy was brought to our attention due to worsening respiratory symptoms and persistent emesis. During hospitalization, the child developed right-sided otalgia followed by otorrhea. An otorhinolaryngologic exam revealed tympanic membrane perforation and discharge. An ear sample culture yielded <i>Vibrio cholerae</i>. A computed tomography scan confirmed the presence of otitis media complicated with otomastoiditis. Treatment with amoxicillin/clavulanate was complemented with ciprofloxacin and dexamethasone otic drops and led to a complete recovery without sequelae. While the child had no predisposing conditions, most published cases of otitis caused by <i>Vibrio spp.</i> describe a history of ear diseases or trauma and water exposure. In a context where vibriosis is increasingly common, our case exemplifies the importance of considering <i>Vibrio spp.</i> among the possible causative agents of otitis, especially in coastal areas or when exposure to potentially contaminated water cannot be ruled out, even in the absence of predisposing conditions.
