Reintroducing URA3 to its native locus in Candida albicans not5, not3, bur2, and kel1 disruption mutants enabled us to directly compare strains with control strain CAI-12. We showed that URA3 position affected orotidine 5'-monophosphate decarboxylase activity, hyphal morphogenesis, adherence, and mortality in murine disseminated candidiasis. After URA3 was reintroduced to its native locus, only...
Glycosylphosphatidyl inositol anchored proteins (GPI-APs) on fungal cell wall are essential for invasive infections. While the function of inositol deacylation of GPI-APs in mammalian cells has been previously characterized the impact of inositol deacylation in fungi and implications to host infection remains largely unexplored. Herein we describe our identification of BST1, an inositol deacyla...
the opportunistic pathogen c.albicans is able to cause disseminated infections in immunocompromised patients. microbiological methods for the diagnosis of invasive candidiasis have many problems including low sensitivity, requirement to invasive clinical sampling such as biopsies or multiple blood cultures and need to expertise laboratory stuff. since pcr has proven to be a powerful tool in the...
Candidiasis can be in various forms, the most dangerous of them are systemic and visceral candidiases. Many researchers believe that using drugs able to stimulate a protective immune response against candidal infections, i.e. immunobiological drugs, is promising direction fight candidiasis, these an alternative antifungal agents. The aim work was compare therapeutic properties inactivated subun...
A method is described for the simultaneous quantitation of D-arabinitol and D-mannose in serum by gas-liquid chromatography as an aid for the diagnosis of disseminated candidiasis. Both variables were observed as per-O-acetylated aldononitrile derivatives in each chromatographic run of sera from immunosuppressed rabbits experimentally infected with Candida albicans 3181A.
The interaction between fluconazole (Flu) and amphotericin B (AmB) was evaluated in a murine model of systemic candidiasis for one Flu-susceptible strain (MIC, 0.5 microg/ml), two strains with intermediate Flu resistance (Flu mid-resistant strains) (MIC, 64 and 128 microg/ml), and one highly Flu-resistant strain (MIC, 512 microg/ml) of Candida albicans. Differences in fungal densities in kidney...
We evaluated the in vitro killing activity of voriconazole (VRC) and posaconazole (PSC) against two clinical isolates of Candida guilliermondii. The two drugs showed fungistatic activity against both isolates and were effective in reducing kidney fungal burden in a neutropenic murine model of disseminated candidiasis in infected mice. PSC was significantly more effective than VRC against one of...
Candida albicans-Endothelial Cell Interactions: a Key Step in the Pathogenesis of Systemic Candidiasis Sarah E. W. Grubb,* Craig Murdoch, Peter E. Sudbery, Stephen P. Saville, Jose L. Lopez-Ribot, and Martin H. Thornhill Department of Oral & Maxillofacial Medicine and Surgery, University of Sheffield, Sheffield, United Kingdom; Department of Molecular Biology and Biotechnology, University of Sh...
Two standardized enzyme immunoassays for the serological diagnosis of candidiasis were developed. The first one detects antimannan antibodies, while the second one detects mannan with a sensitivity of 0.1 ng/ml. These tests were applied to 162 serum samples retrospectively selected from 43 patients with mycologically and clinically proven candidiasis caused by Candida albicans. Forty-three seru...
In this study we defined the pharmacodynamic parameter that optimizes outcome in deep-seated Candida albicans infections treated with fluconazole. Using a murine model of systemic candidiasis, we conducted single-dose dose-ranging studies with fluconazole to determine the dosage of this drug that resulted in a 50% reduction in fungal densities (50% effective dose [ED50]) in kidneys versus the f...
