the agent of many forms of cutaneous leishmaniasis, now considered a complex of several subspecies or possibly species, each with distinctive DNA and enzyme characteristics, distribution, and vector-reservoir host association, resulting in distinct manifestations of human leishmaniasis; reservoir hosts are extremely diverse and include a wide array of arboreal rodents as well as marsupials, primates, and small carnivores. Typical disease forms caused by this species are chiclero ulcer and diffuse cutaneous leishmaniasis, in contrast with mucocutaneous leishmaniasis, more characteristic of Leishmania braziliensis infection.
