Summary

Introduction. Evaluation of Leishmania drug susceptibility depends on in vitro SbV susceptibility assays, which are labour-intensive and may give a biased view of the true parasite resistance. Molecular markers are urgently needed to improve and simplify the monitoring of SbV-resistance. We analysed here the gene expression profile of 21 L. braziliensis clinical isolates in vitro defined as SbV-resistant and -sensitive, in order to identify potential resistance markers. Methods. The differential expression of 13 genes involved in SbV metabolism, oxidative stress or housekeeping functions was analysed during in vitro promastigote growth. Results. Expression profiles were up-regulated for 5 genes only, each time affecting a different set of isolates (mosaic picture of gene expression). Two genes, ODC (ornithine decarboxylase) and TRYR (trypanothione reductase), showed a significantly higher expression rate in the group of SbV-resistant compared to the group of SbV-sensitive parasites (P<0·01). However, analysis of individual isolates showed both markers to explain only partially the drug resistance. Discussion. Our results might be explained by (i) the occurrence of a pleiotropic molecular mechanism leading to the in vitro SbV resistance and/or (ii) the existence of different epi-phenotypes not revealed by the in vitro SbV susceptibility assays, but interfering with the gene expression patterns.
