Taxonomic studies of leishmanial isolates from the New World indicate tremendous diversity within this genus (E Cupolillo et al. 1994 Am J Trop Med Hyg 50: 296-311). A number of new Leishmania species from sylvan areas of the Neotropics have been described recently. Some of those parasites are associated with disease in humans; others appear to be restricted to lower orders of mammals, such as rodents and edentates (G Grimaldi et al. 1989 Am J Trop Med Hyg 41: 687-725). However, some of the latter parasites may yet be shown capable of causing human disease, particularly in persons with altered cellular immune responses.
