Background and Aim: Candidial vulvovaginitis (CVV) is a female genital system infection that occurs due to the overgrowth of Candida species,especially with Candida albicans.This condition may become recurrent.The long administration of the current antifungal drugs may cause resistance. Therefore it is essential to understand the efficacy pattern of therapeutic agents against the isolated Can...
The aim of the present study was to investigate the association between Mrr1, adenylyl cyclase-associated protein 1 (Cap1) and multi-drug resistance gene 1 (MDR1), and to assess the mutations in Mrr1 and Cap1 in azole-resistant Candida albicans strains. The study isolated 68 C. albicans strains from patients with vulvovaginal candidiasis. Drug susceptibility testing was conducted to characteriz...
The AsperGenius® assay detects several Aspergillus species and the A. fumigatus Cyp51A mutations TR34/L98H/T289A/Y121F that are associated with azole resistance. We evaluated its contribution in identifying A. lentulus and A. felis, 2 rare but intrinsically azole-resistant sibling species within the Aspergillus section Fumigati. Identification of these species with conventional culture techniqu...
Cytochrome P-450 catalysing the 14ademethylation of sterol is inhibited in fungi by azole antifungal compounds resulting in a fungistatic or a fungicidal effect [ 11. The azoles themselves represent a useful tool for investigating P-450 structure through the differential affinities with different P450 forms. [Z]. Of practical importance is the identification of the molecular features which resu...
Pdr5p-like ABC transporters play a significant role in azole resistance in Saccharomyces cerevisiae and Candida spp. Most of filamentous fungal species have multiple Pdr5p homologues. In this study, phylogenic analysis identified that filamentous fungi have at least two phylogenically distant groups of Pdr5p homologues. One contains PMR1-like Pdr5p homologues while the other contains both AtrF-...
Saccharomyces cerevisiae has long been used as a model organism in the study of the ergosterol pathway and its inhibitors. The Pdr5 protein (Pdr5p), an ATP binding cassette transporter, plays an important role in active efflux of azole antifungals and therefore in azole sensitivity and resistance in S. cerevisiae. We have identified the Fluconazole Dominant Resistance-1 (FDR-1) mutant, which ha...
