Genomic changes driving the acquisition of multidrug resistance in Candida glabrata

Abstract

This project was set out to broaden our knowledge of the processes driving the emergence of antifungal drug resistance in an opportunistic yeast pathogen Candida glabrata. More precisely, we sought to find the mutational signatures of drug resistance and cross-resistance to representatives of two clinically important antifungal drug classes, azoles and echinocandins. By combining in vitro evolution with phenotypic screening and comparative genomics analysis we investigated the relationship between genomic changes, fitness and drug susceptibility to shed light on the cellular mechanisms and evolutionary constraints of antifungal drug resistance in this important pathogenPrograma de doctorat en Biomedicina
