A case of feline otitis externa due to Microsporum canis.
We describe a case of a 3-month-old Persian male cat with a persistent waxy, ceruminous, otic discharge in both external auditory canals. After microbiological culture, only Microsporum canis was isolated with no concurrent fungal or bacterial flora. Fungal otitis due to dermatophytes was diagnosed and specific treatment with griseofulvin was administered. After 4 weeks of treatment, no M. canis colonies were isolated and clinical recovery had occurred. In view of this case, dermatophytosis should be included in the differential diagnosis of feline otic conditions, particularly when otitis becomes chronic or is refractory to treatment.
