New PCR assay using glucose-6-phosphate dehydrogenase for identification of Leishmania species.

ABSTRACT: Glucose-6-phosphate dehydrogenase (G6PD) is one of the multilocus enzymes used to identify Leishmania by zymodeme analysis. The polymorphic pattern revealed by partial characterization of the gene encoding G6PD generated molecular markers useful in the identification of different Leishmania species by PCR. Initially degenerate oligonucleotides were designed on the basis of data on the conserved active center described for other organisms. Primers for reverse transcription-PCR experiments, designed from the nucleotide sequence of the PCR product, enabled us to characterize the 5' and 3' untranslated regions and the G6PD open reading frame of reference strains of Leishmania (Viannia) braziliensis, Leishmania (Viannia) guyanensis, Leishmania (Leishmania) mexicana, and Leishmania (Leishmania)
