Expression of ERG11, ERG3, MDR1 and CDR1 genes in Candida tropicalis

ABSTRACT:

Introduction

Drug resistance to azoles is a growing problem in the Candida genus.

Objective

To analyze molecularly the genes responsible for fluconazole resistance in Candida tropicalis strains.

Materials and methods

Nineteen strains, with and without exposure to fluconazole, were selected for this study. The expression of MDR1, CDR1, ERG11, and ERG3 genes was analyzed in sensitive, dose-dependent sensitive, and resistant strains exposed to different concentrations of the antifungal drug.

Results

MDR1, ERG11 and ERG3 genes were significantly overexpressed in the different sensitivity groups. CDR1 gene expression was not statistically significant among the studied groups. Seven of the eight fluconazole-resistant strains showed overexpression of one or more of th
