The Neotropical Leishmania species: a brief historical review of their discovery, ecology and taxonomy

Abstract

This paper is a review of the major historical events leading to our present classification of the Neotropical Leishmania species, and apart from indicating the basic type of disease these different parasites may cause in humans, it does not discuss the clinical or epidemiological features of the leishmaniases. For each of these species, information is given on the known geographical distribution, recorded phlebotomine sand fly host(s) and the secondary, wild or domestic mammalian hosts. Reasons are given for regarding the parasite referred to as Leishmania (L.) infantum chagasi, the causative agent of American visceral leishmaniasis, as most probably indigenous to the Neotropics rather than imported during the Iberian colonisation.
