Canine demodicosis associated with malasseziosis

Abstract

Demodicide, commonly known as "Black Scabies" is a skin disease caused by excessive multiplication of the genus Demodex. This work aims to report the case of a three-year-old Bulldogue French dog, attended at the Veterinary Hospital of the Catholic University of Dom Bosco, with lesions on the head and limbs, localized alopecia, hyperpigmentation, erythema, moderate pruritus. Associated with the disease, the animal showed fungal dermatopathy, caused by the fungus Malassezia pachydermatis, in which it showed clinical signs of regional alopecia, rancid smell, and chronic lichenification in the ears, hyperkeratosis, external otitis and localized hypotrichosis. In the parasitological exam of deep skin scrapings forms were observed of Demodex sp. In that case, it was prescribed for the Simparic treatment, Itraconazole and baths with shampoo based on Clorexidine 2%, in order to prevent relapses and control the disease. Another procedure adopted to control the disease is the removal of the females from the reproduction, because it has no cure, only clinical improvement.
