Further characterization of Chinese Leishmania isolates by isoenzyme electrophoresis

Ten Chinese Leishmania isolates from different endemic areas and hosts are characterized by isoenzyme electrophoresis for 9 enzymes. Seven were isolated from visceral leishmaniasis patients, one from an infected dog, one from a sandfly and one from a naturally infected racoon dog. Eight of the 10 isolates were indistinguishable in isoenzyme profile from the L infantum reference strain. The isoenzyme profiles of the remaining two isolates (from kala azar patients in Xinjiang) could not be characterized in this study and need further research.
