Diagnosis of Canine Nasal Aspergillosis in a Dog

A uncastrated male black Labrador had history of intermittent episodes of epistaxis and recurrent paroxysms of sneezing for last two years. Hematology, biochemistry and lateral radiography of chest did not reveal any significant abnormality. A nasal swab taken from both nostrils and smear stained with Leishman stain yielded long uniform and septate hyphae of fungus and was confirmed as nasal aspergillosis. Treatment was instituted with oral Itraconazole, but dog died owing to severe epistaxis.
