A. A phylogenetic analysis of cytochrome b gene was performed by the maximum likelihood method together with sequences from 13 Leishmania species. The scale bar represents 0.02% divergence. Bootstrap values are shown above or below branches. Ting-Ver: Leishmania-positive Pi. verrucarum from Tingo Bajo, Chur-Mar: Leishmania-positive Pi. maranonensis from Nuevo Churuja, 19-7TI-1: a patient’s specimen from Tingo Bajo. B. PCR-RFLP analysis of mannose phosphate isomerase genes from L. (V.) braziliensis (lane 1), L. (V.) peruviana (lane 2), Leishmania-positive Pi. verrucarum from Tingo Bajo (lane 3), a patient’s specimen from Tingo Bajo (lane 4), and Leishmania-positive Pi. maranonensis from Nuevo Churuja (lane 5).
