Malassezia pachydermatis is a lipophilic, saprophytic yeast commonly found on healthy skin, ear canals, and anal sacs, oral and anal mucosal surfaces of dogs. The main skin diseases that favor the proliferation of this opportunistic yeast are atopy, food allergy, hypersensitivity to flea bites and contact allergy. Different endocrinopathies and metabolic diseases can also cause seborrhea, thus promoting the growth of Malassezia, such as hyperadrenocorticism, hypothyroidism, diabetes mellitus, and skin neoplasia. Large amounts of Malassezia are seen in 50% to 80% of dogs with external otitis and They have been shown to cause inflammation, perhaps through interaction of lipid / Malassezia metabolites (eg, peroxide formation) and type I (hypersensitivity) reactions to yeast or its metabolites. Some breeds such as the Cocker Spaniel, Shih Tzu, Basset Hound, German Shepherd Poodle have a higher risk, which may be related to anatomical characteristics such as pendulous ears and specific host factors, there is no predilection for sex, in terms of age. report more cases in adult dogs.
