The genetic diversity of recent clinical isolates of Candida albicans in Japan was studied on the basis of amplified DNA band lengths determined with a specific PCR primer reported to have been designed to span a transposable intron region in the 25S rRNA gene. Our analyses of 301 clinical isolates of C. albicans showed that they could be classified into five genotypes: genotype A (172 isolates...

Chlamydospore formation is a characteristic of many fungal species, among them the closely related human-pathogenic dimorphic yeasts Candida albicans and C. dubliniensis. Whereas function and regulation of filamentation are well-studied in these species, the basis of chlamydospore formation is mostly unknown. Here, we investigate the contribution of environmental and genetic factors and identif...

Yeasts colonize the subgingival biofilm, which becomes a reservoir that favors their reproduction. The purpose of the present work was to determine the prevalence of yeasts of the Candida genus in the subgingival biofilm of gingivoperiodontal disease patients, including users and non-users of dental devices, and their susceptibility to fluconazole and voriconazole. Samples of subgingival pocket...

Candida albicans and Candida dubliniensis are closely related species displaying differences in virulence and genome content, therefore providing potential opportunities to identify novel C. albicans virulence genes. C. albicans gene arrays were used for comparative analysis of global gene expression in the two species in reconstituted human oral epithelium (RHE). C. albicans (SC5314) showed up...

OBJECTIVES Novel highly functionalized bis cyclohexenone ethyl carboxylates 7-12 were designed, synthesized and their structures were elucidated by their elemental analysis, MS, FT-IR, one-dimensional 1H, and 13C NMR spectroscopic data. MATERIALS AND METHODS All the synthesized compounds 7-12 were tested for their in vitro antifungal activities against Candida sp. namely Candida albicans, Can...

BACKGROUND Mucocutaneous candidiasis (almost endogenous) is one of the most common manifestations of human immunodeficiency virus (HIV) infection. The aim of this study was the investigation of colonization patterns of Candida species, particularly C. dubliniensis, among mucosal sites of HIV-positive patients and determining corresponding in vitro susceptibility patterns to the antifungals. M...

The correct identification of Candida species is of great importance, as it presents prognostic and therapeutical significance, allowing an early and appropriate antifungical therapy. The purpose of this study was to identify isolates of Candida spp. from oral mucosa of 38 patients with oral candidosis evaluated in 2004 by phenotypic methods and PCR, discriminating C. albicans from the other Ca...

CHROMagar Candida is a differential culture medium for the isolation and presumptive identification of clinically important yeasts. Recently the medium was reformulated by Becton Dickinson. This study was designed to evaluate the performance of the new formula of CHROMagar against the original CHROMagar Candida for recovery, growth, and colony color with stock cultures and with direct plating o...

In this study, the low molecular weight lypophilic metabolites of C. albicans and C. dubliniensis strains produced in a synthetic medium with the addition of fetal calf serum were identified using LC/MS and MS/MS technique and quantified. All strains investigated produce a metabolite with a UV spectra maximum at 224 and 279 nm and minimum at 243 nm. Following comparison with ESI, MS/MS spectral...
