<i>Leishmania (V.) braziliensis</i> isolates obtained from patients with mucosal/mucocutaneous leishmaniasis show higher ecto-nucleotidase activity.

<p>Promastigotes were isolated on the 5th day of culture and incubated with ATP (A), ADP (B) and AMP (C) for 1 h at 30°C. Enzymatic activity was evaluated by the measurement of inorganic phosphate released. Each point represents a different isolate obtained from mucosal (ML)/mucocutaneous (MCL) lesions (A) or cutaneous lesions (CL). The line represents the mean of the group. (*) indicates statistical difference (p<0.05). Statistical analysis was performed by Students's <i>t</i>-test.
