BACKGROUND Candida species are among the most common causes of opportunistic fungal diseases. Among Candida species, Candida albicans is responsible for most infections. Having many strains, C. albicans is very polymorph. C. dubliniensis is very similar to albicans species both morphologically and physiologically. For an infection to occur, cell wall proteins play an important role as they enab...
The survival of all microbes depends upon their ability to respond to environmental challenges. To establish infection, pathogens such as Candida albicans must mount effective stress responses to counter host defences while adapting to dynamic changes in nutrient status within host niches. Studies of C. albicans stress adaptation have generally been performed on glucose-grown cells, leaving the...
mortality in compromised hosts. It is known that Candida virulence is a function of a multiplicity of factors working jointly to overcome the host defenses. Especially, studies of the pathogenic mechanisms of Candida infections have focused on dimorphism, protease production, cell growth, resistance to phagocytes, and adherence to host tissues. C. albicans is the most commonly isolated and the ...
The fungal pathogen Candida albicans has a multilayered cell wall composed of an outer layer of proteins glycosylated with N- or O-linked mannosyl residues and an inner skeletal layer of beta-glucans and chitin. We demonstrate that cytokine production by human mononuclear cells or murine macrophages was markedly reduced when stimulated by C. albicans mutants defective in mannosylation. Recognit...
An antigen (Ag), as defined by reactivity with a monoclonal antibody (mAb 10G), was found on the cell wall surface and on the plasma membrane of Candida albicans yeast cells (Li, R. K., and Cutler, J. E. (1991) J. Gen. Microbiol. 137, 455-464). The 10G Ag from the cell surface location was solubilized by treatment with beta-mercaptoethanol and Zymolyase. Antigenic activity of the extract was lo...
Disseminated candidiasis is the third leading nosocomial blood stream infection in the United States and is often fatal. We previously showed that disseminated candidiasis was preventable in normal mice by immunization with either a glycopeptide or a peptide synthetic vaccine, both of which were Candida albicans cell wall derived. A weakness of these studies is that, unlike humans, mice do not ...
In this article, we report the silver orthophosphate (Ag3PO4) photocatalytic inactivation properties on strains Gram-positive Saprophyte B. subtilis, a diploid fungus Candida albicans and Gram-negative Pseudomonas aeruginosa, using as irradiation source white-light-emitting diodes (WLEDs) with luminous flux (? v) of 1.3 × 103 Lumens relative power density 15 mW m?2. Microorganisms death curves ...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
BACKGROUND The morphogenetic conversion between yeast and hyphal growth forms appears to be crucial in the pathogenesis of invasive candidiasis, and can be regulated by environmental signals such as extracellular pH. AIMS To characterise the epitope recognised by monoclonal antibody 1H4, and to evaluate the expression of its corresponding epitope in Candida albicans cells under different cond...
Background: Vulvovaginal candidiasis (VVC) is a common infection, affecting up to 75% of women during their lifetimes. Approximately 5% of patients may experience recurrent VVC. Candida albicans is the most common causative agent of VVC. The objectives of this study were identification of candida species isolated of women with vulvovaginal candidiasis by molecular method in Arak city. Methods:...
