An apparent association of enzymic variants of Leishmania major with specific geographical areas in Israel.

Isolates of Leishmania major from man, Psammomys obesus, Meriones crassus and Phlebotomus papatasi from three separate areas of Israel were characterised using isoenzyme electrophoresis. Three enzymic variants of phosphogluconate dehydrogenase (6PGD) were seen, the distribution of which is correlated with the different geographical areas.
