Isoenzyme patterns of Leishmania isolates from Colombia.

Promastigotes from four cutaneous leishmaniasis cases from Colombia were tested by cellulose acetate electrophoresis using nine enzyme systems. The isoenzyme profiles of the Colombian isolates were indistinguishable from each other and from Panamanian Leishmania braziliensis panamensis controls, but were distinct from an isolate of Leishmania braziliensis guyanensis from Brazil and three isolates from the Leishmania mexicana complex for the enzyme phosphogluconate dehydrogenase.
