ABSTRACT
Feline demodicosis caused by Demodex cati is a rare parasitic disease, characterized by local or generalized dermatitis and less commonly by otitis. A feline, male, castrated, mixed breed, 11 years old, presented progressive cervical pruritus with alopecia in the caudolateral region of the right ear and mild erythema, abrasions, brownish ceruminous secretion and otopodal reflex. He had a history of feline immunodeficiency virus (FIV) infection and feline gingivitis stomatitis complex (GSC), in addition to continuous use of prednisolone. In the parasitological examination of the cerumen, different stages of Demodex sp. were found. Genetic sequencing revealed 99.33% homology for D. cati. Therapy with imidacloprid and moxidectin in spot-on formulation, in two doses at 30-day intervals, promoted remission of clinical signs and elimination of the mite.
