In the late 90's there was a change in both the route of transmission and the
people at risk for sporotrichosis. This zoonotic cat-man alternative
transmission route elicited changes in strategies to control the epidemic. There
was a progressive increase in the number of cases involving especially children
and the elderly. In addition to becoming hyperendemic, uncommon clinical
pictures like immunoreactive clinical presentations or severe systemic cases
have emerged. New species were identified and classified through molecular tools
using more virulent clinical isolates, like S. brasiliensis,
compared to the environmental isolates. Likewise, different species of
Sporothrix have been associated with different geographic
regions. The serological and molecular techniques are used as an auxiliary tool
for the diagnosis and/or for species identification, although the isolation and
the identification of Sporothrix spp. in clinical specimen is
still the gold standard. Currently sporotrichosis epidemics requires the
knowledge of the epidemiological-molecular profile to control the disease and
the specific treatment. Itraconazole, potassium iodide, terfinafine, and
amphotericin B are the available drugs in Brazil to treat sporotrichosis. The
drug of choice, its posology, and treatment duration vary according to the
clinical presentation, the Sporothrix species, and host immune
status. New treatment choices, including a vaccine, are being developed;
nevertheless, more clinical trials are required to confirm its efficacy.
