Otodemodicose por demodex cati em felino - Relato de caso

Abstract

Feline demodicosis is a rare dermatopathy characterized by inflammation caused by the excessive growth of mites of the genus Demodex in immunosuppressed cats or those with systemic conditions. Cats can be affected by three species of Demodex. This report describes a clinical case of otodemodicosis, secondary to a case of feline respiratory complex, in a 1-year-old mixed-breed female cat treated at the Veterinary Hospital of the Federal University of Paraíba, in Areia, which presented signs of alopecia in the outer region of the pinnae and external ear canal, along with a moderate amount of brown ceruminous secretion in the ears, with moderate pruritus reported by the owner. Complementary exams, including a blood count, FIV/FeLV test, and parasitological analysis of the cerumen, were performed. The cerumen analysis revealed the presence of Demodex mites. The diagnosis of feline respiratory complex was based on the animal's history and clinical examination, while otodemodicosis was confirmed by laboratory findings. The identification of the Demodex species was based on morphological and literary descriptions, evidencing the presence of Demodex cati, commonly associated with immunosuppressive and systemic diseases. Treatment included the approach for the feline respiratory complex and the administration of selamectin for otodemodicosis.
