Abstract       Background and objectives: More Candida albicans strains are reported resistant to fluconazole in patients with AIDS, cancer and organ recipients. Fluconazole resistance can be attributed to changes in pathways of sterol biosynthesis, mutation in or overexpression of ERG11 and the expression of CDR1, CDR2, and MDR1. This study aimed to compare the ex...

 Background & Objective:  The incidence of biofilm-related infections caused by Candida albicans has increased dramatically. C. albicans biofilm-related infections are more resistant to antifungal medications. This work was an attempt to examine inhibitory effects of fluconazole in combination with amphotericin B on fluconazole-resistant C. albicans biofilm.  Materials & Methods:  Fluconazole-...

Background and Purpose: The frequency of opportunistic fungal infections in immunocompromised patients, especially by Candida species, has sharply increased in the last few decades. The objective of this study was to analyse the ergosterol content and gene expression profiling of clinical isolates of fluconazole resistant Candida albicans. Materials and Methods: Sixty clinical samples were ide...

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...

Abstract Background and Objective: With the development of drug resistance in strains of fungi, there is a considerable resistance of Candida albicans strains to fluconazole. Molecular studies are developing to determine the relationship of such a drug resistance with the increased gene expression of enzymes produced in drug-resistant Candida isolates. We aimed to evaluate the relationship betw...

Susceptibilities to amphotericin B and fluconazole of 628 clinical yeast strains collected from 22 hospitals in Taiwan were determined. A total of 53 isolates (8.4%) were resistant to fluconazole. Each hospital had different resistance rate to fluconazole ranging from 0% to 24%. None of the 186 isolates from eight of the 22 hospitals was resistant to fluconazole. In contrast, isolates from nine...

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. ...

The echinocandin class of antifungal agents is considered to be the first-line treatment of bloodstream infections (BSI) due to Candida glabrata. Recent reports of BSI due to strains of C. glabrata resistant to both fluconazole and the echinocandins are of concern and prompted us to review the experience of two large surveillance programs, the SENTRY Antimicrobial Surveillance Program for the y...
