Leishmania Leish·man·i·a (lēsh-mān'ē-ə, -mā'nē-ə)
A genus of flagellate protozoa, several species of which cause leishmanisis; all species are indistinguishable morphologically but may be separated by their serological reactions, by their geographic distribution, by their developmental patterns in their sandfly hosts, and by their clinical manifestations of leishmaniasis.
