Abstract:
Twelve Leishmania isolates from visceral leishmaniasis patients in eastern Sudan were characterized using isoenzyme analysis, Southern blotting and polymerase chain reaction (PCR) 'fingerprinting'. Isoenzyme analysis revealed the presence of 3 zymodemes: MON-18, MON-30 and MON-82, corresponding to Leishmania donovani sensu stricto, L. infantum and L. archibaldi (still of uncertain taxonomic status), respectively. Southern blotting and PCR 'fingerprinting' revealed identical patterns for all 3 zymodemes, which were indistinguishable from those of L. donovani s.s.
