Prevalência de microrganismos e ácaros encontrados em amostras dermatológicas e otológicas de cães e gatos

Abstract

Dermatopathies and otopathies are recurrent cases in veterinary clinic caused by different microorganisms. The aim of the present study is to analyze reports of cytological and parasitological skin and ear examinations performed at the Clinical Laboratory of the Veterinary Teaching Clinic of Federal University of Juiz de Fora in order to determine the prevalence of bacteria, fungi and mites in the collected samples. Reports of tests carried out from January 2018 to December 2019 were analyzed. Dog otopathies comprised 42 (50%) cases caused by Malassezia sp., 11 (13.1%) cases caused by bacteria and 29 (34.5%) cases caused by mixed infections; whereas cats otopathies encompassed 7 (28%) infections caused by Malassezia sp., 3 (12%) infections caused by bacteria, 6 (24%) mixed infections and 3 (12%) infections caused by mite species Otodectes cynotis. Dog dermatopathies comprised 1 (2.6%) case caused by Malassezia sp., 17 (43.6%) cases caused by bacteria, 7 (17.9%) mixed infections and 3 (7.7%) infections caused by mite species Demodex canis; whereas cat dermatopathies comprised 2 (15.4%) changes caused by bacteria, 3 (23.1%) mixed infections, 2 (15.4%) infections caused by Sporothrix sp., 1 (7.6%) caused by dermatophyte and 3 (23.1%) by yeast. Results have shown that Malassezia sp. was the most prevalent etiological agent in ear diseases diagnosed in both dogs and cats. On the other hand, bacteria were the most prevalent agents in dog skin disorders, whereas mixed infections and fungal agents recorded similar prevalence in cats.
