Titration curve of IgG antibodies anti-fixed Leishmania braziliensis promastigotes from the sera of patients with American tegumentary leishmaniasis (ATL n = 15); non-infected individuals (NI n = 8) and spontaneously cured patients (CUR n = 8) (a). IgG antibodies anti-fixed Leishmania braziliensis from serum samples of ATL, NI and CUR groups at the 1/1024 dilution (b). The results were expressed as percentage of positive fluorescent parasites (PPFP). The dotted line represents the cut-off point between negative and positive results (cut-off = 20%)
