The effect of marine polyunsaturated fatty acids on biofilm formation by the human pathogens Candida albicans and Candida dubliniensis was investigated. It was found that stearidonic acid (18:4 n-3), eicosapentaenoic acid (20:5 n-3), docosapentaenoic acid (22:5 n-3) and docosahexaenoic acid (22:6 n-3) have an inhibitory effect on mitochondrial metabolism of both C. albicans and C. dubliniensis ...

Polymicrobial intra-abdominal infections (IAIs) are clinically prevalent and cause significant morbidity and mortality, especially those involving fungi. Our laboratory developed a mouse model of IAI and demonstrated that intraperitoneal inoculation with Candida albicans or other virulent non-albicans Candida (NAC) species plus Staphylococcus aureus resulted in 70 to 80% mortality in 48 to 72 h...

There is a high interest in Candida species other than Candida albicans because of the rise and the epidemiological shifts in candidiasis. These emerging Candida species are favored by the increase of immunocompromised patients and the use of new medical practices, and m. Most oropharyngeal candidiasis can be foundare observed in those HIV-infected patients infected with human immunodeficiency ...

We developed a rapid genotypic assay to differentiate the germ tube-positive yeasts Candida albicans and Candida dubliniensis. Fluorescently labeled nucleic acid probe binding and subsequent denaturation from the target site in the PCR amplicons produced characteristic peak melting temperatures (T(m)) that identified each species. Peak T(m)s of C. albicans (n = 69) and C. dubliniensis (n = 28) ...

Candida dubliniensis is a recently described species that shares many phenotypic and morphological features with Candida albicans. The clinical significance of isolating C. dubliniensis from the pediatric population is not clear, as most clinical isolates have been recovered from the oral cavities or bloodstreams of adults infected with human immunodeficiency virus. In order to understand furth...

although candida albicans is the most common etiologic agent of candidiasis, c. dubliniensis, has been emerged, as another pathogen resembles c. albicans in many phenotypic aspects and noted for its in vitro potential for fluconazole resistance. since there was no evidence of any report about detection of this organism in iran, this study was designed to use of five different tests for identifi...

Candida dubliniensis is a recently described species of pathogenic yeast that shares many phenotypic features with Candida albicans. It is primarily associated with oral colonization and infection in HIV-infected individuals. Isolates of C. dubliniensis are generally susceptible to commonly used azole antifungal agents; however, resistance has been observed in clinical isolates and can be induc...

We describe what appears to be the first case of spondylodiscitis due to Candida dubliniensis. Our case adds to the current literature of the importance of C. dubliniensis as a cause of fungemia and subsequent deep seated infections. It highlights the importance of taking fungal as well as bacterial culture from biopsy specimens in patients with spondylodiscitis. We also review the literature c...

A variety of fungi produce the hydrolytic enzyme beta-N-acetylhexosaminidase (HexNAcase), which can be readily detected in assays by using p-nitrophenyl-N-acetyl-beta-D-glucosaminide as a substrate. In the present study we developed a microtiter plate-based HexNAcase assay for distinguishing Candida albicans and Candida dubliniensis strains from other yeast species. HexNAcase activity was detec...

Candida albicans, the most common facultative human pathogenic fungus is of major medical importance, whereas the closely related species Candida dubliniensis is less virulent and rarely causes life-threatening, systemic infections. Little is known, however, about the reasons for this difference in pathogenicity, and especially on the interactions of C. dubliniensis with the human immune system...
