Resumo: Objective. To analyze the presence of yeast in the external ear canal of 116 dogs with and without a diagnosis of otitis from veterinary clinic in the Chapecó city, Santa Catarina, Brazil, and to examine the secretion of the proteinase in isolates. Materials and methods. Were collected cerumen of conduct hearing of dogs of 16 different races 71% with pendular ear type, 5% of semi-pendular and 24% of the erect type. All dogs were previously evaluated by otoscopy and grouped in dogs with and without otitis. Results. Yeasts were isolated in 44 samples (approximately 36%), where Malassezia pachydermatis was identified in 95% of samples where were observed growth of yeasts. On 20 samples the proteinase enzyme showed strong activity in 31% isolates, were 21% of the dogs with otitis tested showed high proteolytic activity. Conclusions. We observed a variation of strains of M. pachydermatis-producing enzymes. The variation in production of these enzymes is probably more associated with different response to the action of the immune system of the animal in the tissue injury.

Materiales y métodos. Se recogieron cerumen del oído de perros de 16 razas diferentes, dónde 71% fue de oído de tipo pendular, 5% de semi-pendular y 24% del tipo erecto. Todos los perros fueron evaluados previamente por otoscopia y agrupados en perros con y sin otitis externa. Resultados. Las levaduras se aislaron en 44 muestras (aproximadamente 36%), donde Malassezia pachydermatis se identificó en el 95% de las muestras donde se observó el crecimiento de las levaduras. El 20 muestras la secreción de proteinasa mostró fuerte actividad en el 31% de los aislados y en 21% de los perros con otitis mostró alta actividad proteolítica. Conclusiones. Hemos observado una variación de cepas de M. pachydermatis productoras de enzimas. La variación en la producción de estas enzimas es probablemente más asociados con la respuesta diferente a la acción del sistema inmunológico del animal en la lesión tisular.application/pdfengRevista MVZ córdoba.
