Case report-Subjects-Three cases are described oflong-standing vaginal candidosis due to Candida glabrata. These had failed to respond to local and systemic antifungals. In each case the infecting strain appeared resistant to a range of azole drugs in vitro. Clinical course-Case one-This patient recovered following prolonged treatment with oral itraconazole in combination with oral and vaginal ...

In vitro activities of antifungal agents, including azole compounds, against yeasts were easily determined by using RPMI-1640 agar medium and by incubating the plates in the presence of 20% CO2. The end point of inhibition was clear by this method, even in the case of azole compounds, because of the almost complete inhibition of yeast growth at high concentrations which permitted weak growth of...

To the Editor: We read with interest the report by van der Linden et al. about the prevalence of azole-resistant Aspergillus fumigatus isolates from 19 countries, including 2 from the Americas (Brazil and the United States) (1). Recent reports have suggested a link between use of fungicides in agricultural practices and the presence of triazole-resistant A. fumigatus among azole-naive persons (...

Background and Purpose: Candida albicans is the most common Candida species (spp.) isolated from fungal infections. Azole resistance in Candida species has been considerably increased in the last decades. Given the toxicity of the antimicrobial drugs, resistance to antifungal agents, and drug interactions, the identification of new antifungal agents seems essential. In this study, we assessed t...

Posaconazole is the newest azole antifungal approved by the US Food and Drug Administration, and possesses a broad spectrum of activity against numerous yeasts and filamentous fungi. It is available as an oral suspension and is generally well tolerated by patients, but gastrointestinal absorption is sometimes inadequate and remains a clinical concern in treating deep-seated infections. It is us...

A case of chronic sinus disease due to morphologically atypical Aspergillus flavus is described. Multiple fungal isolates sporulated poorly or not at all, displaying unusual color and microscopic morphology, including the absence of typical vesicles and phialides, which caused the isolates to resemble several other fungal genera superficially. The patient received multiple antifungal therapies ...

Irradiation effects were investigated in zircon crystals by methods of optical absorption and luminescence. Special attention was given to the effects of vacuum ultraviolet (VUV) radiation. The same main thermoluminescence (TL) peaks with the same thermal activation energies appeared after VUV as after X- or beta irradiation, indicating that the same traps were induced by the different irradiat...

The title compound, [Cu(4)Br(4)(C(21)H(22)Br(2)N(4))(4)], features a macrocyclic Cu(4)L(4) ring system in which each Cu(I) atom is coordinated by one bromide ion and two N atoms from two 2,2'-dimethyl-1,1'-[2,2-bis-(bromo-meth-yl)propane-1,3-di-yl]di(1H-benzimidazole) (L) ligands in a distorted trigonal-planar geometry. The L ligands adopt either a cis or trans configuration. The asymmetric uni...
