Yamamoto, Yoshihisa Hashiguchi To obtain further insight into geographic distribution ofLeishmania species in Peru, a countrywide survey, including central to southern rainforest areas where information on causative parasite species is limited, was performed based on cytochromeb (cyt b) and mannose phosphate isomerase (mpi) gene analyses. A total of 262 clinical samples were collected from patients suspected of cutaneous leishmaniasis (CL) in 28 provinces of 13 departments, of which 99 samples were impregnated on FTA (Flinders Technology Associates) cards and 163 samples were Giemsa-stained smears.Leishmania species were successfully identified in 83 (83.8%) of FTA-spotted samples and 59 (36.2%) of Giemsa-stained smear samples. Among the 142 samples identified, the most dominant species wasLeishmania (Viannia) braziliensis (47.2%), followed byL.(V.) peruviana (26.1%), and others wereL.(V.) guyanensis,L.(V.) lainsoni,L.(V.) shawi, a hybrid ofL.(V.) braziliensis andL.(V.) peruviana, andLeishmania (Leishmania) amaz...
