The main factor of feline sporotricosis is the action of the fungus Sporothrix schenckii, being a chronic or subacute disease transmissible among domestic animals, also affecting humans. With increasing rates of transmission from felines to humans, zoonosis is worrying, both for health policies and for animal protection policies, since many animals are abandoned when contracting sporotrichosis, generating greater risks of spreading the disease among humans and other animals. Therefore, the objective of the article is to demonstrate that the disease can be successfully treated through the report of clinical experience. The method used for diagnosis was by imprinting the lesion, where the presence of the fungus Sporothrix schenckii was found in the yeast form with degenerated neutrophils and macrophages. The treatment performed was with Itraconazole at a dose of 100mg/day in the manipulated, similar and original versions, showing through the report the greater effectiveness of the original version of the drug.
