The objective of this study was to evaluate whether Candida albicans exhibits altered pathogenicity characteristics following sublethal antimicrobial photodynamic inactivation (APDI) and if such alterations are maintained in the daughter cells. C. albicans was exposed to sublethal APDI by using methylene blue (MB) as a photosensitizer (0.05 mM) combined with a GaAlAs diode laser (λ 660 nm, 75 m...

The effects of amphotericin B and fluconazole on the extracellular and intracellular growth of Candida albicans were studied. With respect to the extracellular growth of C. albicans, antifungal activity was measured in terms of MICs and minimal fungicidal concentrations as well as by determination of the concentration that effectively killed (greater than 99.9%) C. albicans in the absence or pr...

Prokaryote-eukaryote interactions are ubiquitous and have important medical and environmental significance. Despite this, a paucity of data exists on the mechanisms and pathogenic consequences of bacterial-fungal encounters within a living host. We used the nematode Caenorhabditis elegans as a substitute host to study the interactions between two ecologically related and clinically troublesome ...

Candida albicans, the most common human fungal pathogen, can cause systemic infections with a mortality rate of ~40%. Infections arise from colonization of the gastrointestinal (GI) tract, where C. albicans is part of the normal microflora. Reducing colonization in at-risk patients using antifungal drugs prevents C. albicans-associated mortalities. C. albicans provides a clinically relevant sys...

The yeast Candida albicans is an oral commensal microorganism, occurring in the oral cavity of 50-70% of healthy individuals. Its effect on oral ecology has mostly been studied using dual-species models, which disregards the complex nature of oral biofilms. The aim of this study was to culture C. albicans in a complex model to study its effect on oral biofilms. Biofilms, inoculated using pooled...

Native-polyacrylamide gel electrophoresis (N-PAGE) was used to characterize Candida albicans strains isolated from vaginal specimens of patients suffering from vaginitis in Ankara hospitals, Turkey. Three different protein band profiles were observed among these 38 C. albicans isolates when whole cell protein extracts of these strains were used in N-PAGE. 34 of the 38 isolates were shown to bel...

Fungal infections of mucosal surfaces are extremely common, debilitating and often recurring diseases, which are frequently caused by the yeast Candida albicans. Furthermore, in the severely immunocompromised host, C. albicans may also cause deepseated or even life-threatening systemic infections. In order to colonize, infect and evade host defence mechanisms, C. albicans possesses a repertoire...

BACKGROUND Photodynamic therapy (PDT) has been found to be effective in inhibiting biofilm producing organisms. We investigated the photodynamic effect of gold nanoparticle (GNP) conjugated photosensitizers against Candida albicans biofilm. We also examined the photodynamic efficacy of photosensitizer (PS) conjugated GNPs (GNP-PS) to treat skin and oral C. albicans infection in BALB/c mice. M...

A study of 27 clinical specimens from which Neisseria gonorrhoeae and Candida albicans were isolated simultaneously indicated that 44% of the gonococcal isolates were resistant to inhibition by the C. albicans with which they were found and an additional 33% were totally resistant to inhibition by all C. albicans tested. All 27 C. albicans showed inhibitory activity against standard indicator s...

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 ...
