23% by C. albicans and 32% by other Candida spp. The susceptibility profile of all candidal isolates showed that 92% were sensitive to amphotericin B, 36% to fluconazole, 24% to itraconazole, 56% to voriconazole and 96% to flucytosine. Notably, while all strains of C. albicans were susceptible to amphotericin B, 42% were resistant to fluconazole. C. tropicalis, the most commonly isolated specie...

BACKGROUND Some genes may be associated with Candida albicans resistance to azoles. Pir1 gene is described as responsible to induce resistance in C. albicans. OBJECTIVES The current study aimed to find the relationship between fluconazole resistance and Pir1 protein (Pir1p) overexpression in the females with recurrent C. albicans vaginitis requiring longer fluconazole therapy. PATIENTS AND ...

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...

The treatment of vulvovaginal candidiasis (VVC) due to Candida glabrata is challenging, with limited therapeutic options. Unexplained disappointing clinical efficacy has been reported with systemic and topical azole antifungal agents in spite of in vitro susceptibility. Given that the vaginal pH of patients with VVC is unchanged at 4 to 4.5, we studied the effect of pH on the in vitro activity ...

conclusions totally, our results showed nanosilver caused an increase of at least nine-fold in inhibitory effect of fluconazole. materials and methods we studied effect of fluconazole, nanosilver, and their combination on 20 fluconazole-resistant c. albicans from two centers and one standard sample (atcc10261) by minimal inhibitory concentration (mic) method. background opportunistic fungi caus...

OBJECTIVE To determine the susceptibilities of Candida species isolated from Taiwan to amphotericin B and fluconazole. DESIGN Prospective surveillance study. METHODS Each hospital was asked to submit up to 10 C. albicans and 40 non-albicans Candida species during the collection period, from April 15 to June 15, 1999. One isolate was accepted from each episode of infection. The broth microdi...

Antibiotic activities of culture filtrates from twenty filamentous fungi, isolated from wood submerged in tropical freshwater habitats, were tested against a pathogenic strain of Candida albicans. These taxa were fermented separately in liquid medium in pure culture, while another set was fermented with the addition of a fluconazole-sensitive strain of Candida albicans in mix-culture. Fermentat...

INTRODUCTION Candida dubliniensis, a new species of Candida that has been recovered from several sites in healthy people, has been associated with recurrent episodes of oral candidiasis in AIDS and HIV-positive patients. This species is closely related to C. albicans. The enzymatic activity of C. dubliniensis in response to oxidative stress is of interest for the development of drugs to combat ...
