Background and Aims: Candida albicans (C. albicans) is the most common opportunistic human pathogen. Therapeutic options for Candida infections are limited to available antifungal drugs. The aim of this study was to investigate the effects of fluconazole/clotrimazole (FLU/CLT) on C. albicans hyphae formation. Materials and Methods: We have established the effectiveness of the combination of FL...

background: due to the predisposing conditions in patients with cystic fibrosis (cf) caused by defective mucociliary clearance facilitating colonization and invasion with candida species has dramatically increased. traditional methods for identifying problems are imminent and time-consuming. therefore, molecular techniques utilizing amplification of target dna provide quick and precise methods ...

Specialized Candida albicans cell surface proteins called adhesins mediate binding of the fungus to host cells. The mammalian transglutaminase (TG) substrate and adhesin, Hyphal wall protein 1 (Hwp1), is expressed on the hyphal form of C. albicans where it mediates fungal adhesion to epithelial cells. Hwp1 is also required for biofilm formation and mating thus the protein functions in both fung...

OBJECTIVE The protein Hwp1, expressed on the pathogenic phase of Candida albicans, presents sequence analogy with the gluten protein gliadin and is also a substrate for transglutaminase. This had led to the suggestion that C. albicans infection (CI) may be a triggering factor for Celiac disease (CeD) onset. We investigated cross-immune reactivity between CeD and CI. METHODS Serum IgG levels a...

The cell wall protein Hwp1 was originally demonstrated to be expressed exclusively in hyphae of Candida albicans and cross-linked to human epithelium by mammalian transglutaminase. Hwp1 is expressed on the walls of hyphae formed by a/alpha, a/a, and alpha/alpha cells. Hence, it is expressed on hyphae independently of mating type. However, Hwp1 is selectively expressed on the wall of conjugation...

Filamentous growth is an important virulence trait of the human pathogenic fungi within the genus Candida, and the greater propensity of C. albicans to form hyphae has been proposed to account for the greater virulence of this species relative to the less pathogenic species C. dubliniensis. In this meta-analysis, we compare the transcriptional response of C. dubliniensis and C. albicans to the ...

BACKGROUND Biofilms are surface-associated microbial communities with significant environmental and medical impact. Here, we focus on an adherence mechanism that permits biofilm formation by Candida albicans, the major invasive fungal pathogen of humans. RESULTS The Als surface-protein family has been implicated in biofilm formation, and we show that Als1 and Als3 have critical but redundant ...

HWP1 encodes an adhesin of Candida albicans and has been implicated in filamentation and virulence. URA3, an often-used transformation selection marker, is apparently incorrectly expressed when integrated at the HWP1 locus, which results in an attenuated virulence phenotype. Expression of URA3 is compromised by ectopic integration at other loci as well. In contrast, prior studies from the autho...

Previous evaluation of HWP1 in systemic candidiasis in CBA/J mice was done with Candida albicans strains with differing genetic locations of URA3 as a result of Ura-blaster mutagenesis. In this study, the presence of HWP1 and the location of URA3 contributed to the severity of murine systemic candidiasis in BALB/c mice.
