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 Vibrio cholerae. 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 Vibrio spp. 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 Vibrio spp. 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.
