PURPOSE The goal of this study was to compare the adhesion of Candida albicans to the surfaces of CAD/CAM and conventionally fabricated complete denture bases. MATERIALS AND METHODS Twenty discs of acrylic resin poly (methyl methacrylate) were fabricated with CAD/CAM and conventional procedures (heat-polymerized acrylic resin). The specimens were divided into two groups: 10 discs were fabrica...
Macrophages, cells effective in sensing, internalizing and killing Candida albicans, are intertwined with the extracellular matrix (ECM) through different signals, which include release of specific cytokines. Due to importance these interactions, employment vitro models mimicking a fungal infection scenario is essential evaluate ECM effects on macrophage response. In this work, we have analyzed...
Background and Purpose: Early detection of Candida species in body site could improve the survival of the immunosuppressed patients by allowing the initiation of specific treatment while the fungal biomass is still low. The aim of this study was the identification of Candida albicans isolated from the oncology patients by molecular methods. Materials and Methods: Sixty two of Candida albic...
Increased intravenous catheter use has been paralleled by increased bacterial and yeast bloodstream infection. Biofilm formation, which is associated with the cell surface hydrophobicity (CSH) phenotype, represents a major pathogenicity strategy of , becoming especially important in the colonization Candida albicans of intravascular medical devices. Increasing evidence shows the induction of vi...
The fungal pathogen Candida albicans can mate under highly controlled conditions. It can also undergo phenotypic switching. A recent discovery joins these disparate processes to reveal that 'opaque' switch variants mate 10(6) times better than 'white' variants.
Introduction & Objective: Nowadays,herbal extracts are used to treat diseases, especially infectious ones. Candida albicans is the most common causes of oral opportunistic infections.In this study, antifungal effects of two herbal extracts were evaluated on an oral pathogen i.e. Candida albicans. Materials & Methods: In this descriptive- analytic study, the Department of Prosthodontics, ,Teh...
Secretion of hydrolytic enzymes is considered a virulence factor in Candida spp. Extracellular enzymatic activities in 29 clinical isolates of Candida tropicalis were analyzed by plate assays. C. tropicalis, similar to Candida albicans, showed elevated hemolytic and esterase activities. However, unlike C. albicans, low aspartyl protease and very low phospholipase activities were detected in C. ...
Proposed herein is a mechanism for virulence by Candida albicans based upon this organism's ability to produce high levels of pyruvate, potentially resulting in localized tissue ketosis and undermining the normal defensive function of neutrophil myeloperoxidase. Neutrophils, a key component of our innate defense against microbial infections, seem to play a particularly important role protecting...
Candida dubliniensis is the closest known relative of Candida albicans, the most pathogenic yeast species in humans. However, despite both species sharing many phenotypic characteristics, including the ability to form true hyphae, C. dubliniensis is a significantly less virulent and less versatile pathogen. Therefore, to identify C. albicans-specific genes that may be responsible for an increas...
In vitro assays demonstrate photoreactivating enzyme activity in extracts of Candida pseudotropicalis but not in extracts of Candida albicans, Candida stellatoidea, or Candida tropicalis.
