Isoenzyme characterization of Leishmania species from Iraq.

Leishmaniasis in Iraq takes both the visceral and cutaneous forms. The causative organisms are identified according to the electrophoretic variation of the enzymes MDH, GPI, 6PGD, PGM and IDH. The 37 visceral stocks investigated fall into two groups which differ only with respect to GPI. The six cutaneous stocks were divided into three groups. Group 3 represents Leishmania major, while groups 4 and 5 refer to L. tropica showing intraspecific variation with regard to 6PGD.
