Sporotrichosis is a subcutaneous mycosis, caused by the Sporothrix sp. The causal
agent is monospecific and dimorphic, having distinct micro and macromorphological
aspects, depending on the substrate and temperature, in the so-called room
temperature (25oC) it is filamentous and at 37oC, it is yeast-like. Epidemiologically, the
infection has a worldwide distribution, today evidenced mainly in the urban
environment, being more evident in tropical and subtropical climatic conditions.
Domestic cats are commonly associated with this disease due to the large amount of
yeasts in their lesions, the instinct to scratch trees, bury waste and fight in disputes
over territory. The most common clinical signs in this species are ulcerative lesions on
the face, in the distal part of the limbs or the base of the tail, in addition to alopecia and
crusts. In this species, severe clinical manifestations can occur, with systemic
involvement. The diagnosis is made by collecting material from the affected areas for
culture and isolation of the fungus, combined with presumptive and laboratory tests.
As a form of treatment, inorganic iodides are used, especially Itraconazole orally,
because it has less adverse effects in this species.
