Nucleotide substitutions in the Candida albicans ERG11 gene of azole-susceptible and azole-resistant clinical isolates.
One of the mechanisms of Candida albicans resistance to azole drugs used in antifungal therapy relies on increased expression and presence of point mutations in the ERG11 gene that encodes sterol 14α demethylase (14DM), an enzyme which is the primary target for the azole class of antifungals. The aim of the study was to analyze nucleotide substitutions in the Candida albicans ERG11 gene of azol...
متن کاملMUTATION IN HOTSPOT REGIONS OF THE ERG11 GENE AND FLUCONAZOLE RESISTANCE IN CLINICAL ISOLATES OF CANDIDA ALBICANS IN RASHT CITY
Background & Aims: Nowadays, the common use of azoles has led to increased resistance to azole among Candida albicans strains. Amino acid substitutions in azole target enzyme, ERG11p, is attributed to azole resistance in some clinical strains of Candida albicans. The aim of this study was to evaluate ERG11 gene mutations in fluconazole-resistant isolates of Candida albicans in Rasht. Materials...
متن کاملContribution of clinically derived mutations in ERG11 to azole resistance in Candida albicans.
In Candida albicans, the ERG11 gene encodes lanosterol demethylase, the target of the azole antifungals. Mutations in ERG11 that result in an amino acid substitution alter the abilities of the azoles to bind to and inhibit Erg11, resulting in resistance. Although ERG11 mutations have been observed in clinical isolates, the specific contributions of individual ERG11 mutations to azole resistance...
متن کاملReduced azole susceptibility in genotype 3 Candida dubliniensis isolates associated with increased CdCDR1 and CdCDR2 expression.
Candida dubliniensis is a recently identified yeast species primarily associated with oral carriage and infection in individuals infected with the human immunodeficiency virus. The species can be divided into at least four genotypes on the basis of the nucleotide sequence of the internal transcribed spacer region of the rRNA operon. Previous studies have shown that a small number of clinical is...
متن کاملInvestigation of Mutations of ERG11 Gene in Fluconazole Resistant Strains of Candida Albicans Isolated From Patients With Volvovaginitis in West of Mazandaran
Background and Aims: Candida albicans as an opportunistic fungal pathogen in human is the cause of volvovaginitis candidiasis. Azole resistance is cinsiderable as worldwide problem in treatment of candidiasis. Azole resistance can occur through different mechanisms such as mutation in ERG11 gene. The aim of our study was evaluation of ERG11 gene mutations in fluconazole resistant islotes of C. ...
