Recurrent pyoderma with Malassezia and hyperadrenocorticism in a dog.
A dog was referred to the College Hospital of College of Veterinary Science, Tirupati with a history of recurrence of skin problems for the past one year despite the treatment with different antibiotics alongwith corticosteroids at different dose rates without complete relief. Clinical examination revealed skin lesions all over the body with mild enlargedment of abdomen. Laboratory examination revealed cocci; neutrophils and Malassezia, suggestive of pyoderma associated with Malassezia. Staphylococcus intermedius and Klebsiella sps. were revealed upon cultural sensitivity test (CST) studies. Dog had mild anaemia, elevated cholesterol, alkaline phosphatase (ALP) and alanine aminotransferase (ALT) but normal total T4 (3.8 μg/dL) and free T4 (1.85 ng/dL). Further anamnesis based on biochemical analysis revealed polyuria and polydipsia also, suggestive of presence of hyperadrenocorticism. Dog was successfully treated with enrofloxacin and ketoconazole.
