BACKGROUND Dermatophytes are the most common cause of superficial fungal infections in humans. Deep dermatophytosis, however, is rare, described to date only in isolated case reports, usually in the setting of systemic immunosuppression. OBJECTIVE To present the 15-year experience of a tertiary dermato-mycology clinic with the diagnosis and treatment of deep dermatophytosis. METHODS Patient...
Treatment of systemic fungal infections is difficult because of the limited number of antimycotic drugs available. Thus, there is an immediate need for simple and innovative systems to assay the contribution of individual genes to fungal pathogenesis. We have developed a pathogenesis assay using Caenorhabditis elegans, an established model host, with Saccharomyces cerevisiae as the invading fun...
The amphiphilic polyene amphotericin B, a powerful treatment for systemic fungal infections, is shown to exhibit a critical aggregation concentration, and to form giant helically-twisted nanostructures via self-assembly in basic aqueous solution.
BACKGROUND Recurrence of prior invasive fungal infection (relapse rate of 30-50%) limits the success of stem cell transplantation. Secondary prophylaxis could reduce disease burden and improve survival. DESIGN AND METHODS A prospective, open-label, multicenter trial was conducted evaluating voriconazole (4 mg/kg/12 h intravenously or 200 mg/12 h orally) as secondary antifungal prophylaxis in ...
Although normally commensals in humans, Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata, and Candida krusei are capable of causing opportunistic infections in individuals with altered physiological and/or immunological responses. These fungal species are linked with a variety of infections, including oral, vaginal, gastrointestinal, and systemic infections, with C. ...
Ergosterol is an important constituent of fungal membranes. Azoles inhibit ergosterol biosynthesis, although the cellular basis for their antifungal activity is not understood. We used multiple approaches to demonstrate a critical requirement for ergosterol in vacuolar H(+)-ATPase function, which is known to be essential for fungal virulence. Ergosterol biosynthesis mutants of S. cerevisiae fai...
Background and Purpose: Soil is the main habitat of saprophytic and pathogenic fungi. Mucormycetes are one of the most parts of soil fungi and certain members are among opportunistic fungi and can cause systemic fungal infections in immunocompromised patients. The majority of human and animal infections are caused by members of the genera Rhizopus, Mucor, Rhizomucor, Lichtheimia (Absidia), Cunn...
Fungal infections are affecting millions of people in the world every year. Severity range from superficial mycoses to more chronic systemic mycoses. As fungi species evolve, emergence drug resistant strains is becoming a serious concern public health. There now less number effective antifungal drugs available market for treatment invasive fungal infections. In an effort combat this escalating ...
Invasive mycoses are a significant and growing public health problem. Although bloodstream infections with Candida albicans may be decreasing in frequency, the number of persons at risk for them continues to grow. Moreover, infections with other Candida species, such as Candida glabrata, are increasing in incidence. Invasive mould infections in general, and Aspergillus infections in particular,...
BACKGROUND Although the new intensive chemotherapeutic programs introduced recently into hematooncological therapies have led to a higher number of recoveries, persistent neutropenia favours the spread of severe infections, frequently fungal infections. Systemic fungal infections in patients treated for proliferative diseases of the hematopoietic system are characterised by a severe, progressin...
