title: Identification of Leishmania species by a specific DNA probe that is conserved only in the maxicircle DNA of human-infective Leishmania parasites.
abstract: An A + T-rich repeated DNA sequence cloned from maxicircle DNA of Leishmania mexicana amazonensis was found to be conserved in the maxicircles of human-infective Leishmania species but totally absent from non-human-infective ones. Differences in the pattern of distribution of this repeated sequence in the maxicircles of each human-infective Leishmania species potentially allow the development of a sensitive probe to differentiate among these species.
