Energetic metabolism of axenic promastigotes of Leishmania (Viannia) braziliensis

► Comparison of the energetic metabolism of L. (V.) braziliensis strain and isolates. ► The M2903 reference strain has a TCA with greater activity than the isolates. ► Increased TCA activity may reflect differences in host-parasite relationships. ► Biochemical differences indicate possible adaptations of the parasite.
