| Abstract Recent studies have shown that some drugs that are not routinely used to treat fungal infections have antifungal activity, such as protease inhibitor antiretroviral drugs. This study investigated the in vitro susceptibility of Histoplasma capsulatum var. capsulatum to saquinavir and ritonavir, and its combination with the antifungal itraconazole. The susceptibility assay was performed according to Clinical and Laboratory Standards Institute guidelines. All strains were inhibited by the protease inhibitor antiretroviral drugs. Saquinavir showed minimum inhibitory concentrations ranging from 0.125 to 1 μg mL−1 for both phases, and ritonavir presented minimum inhibitory concentrations ranging from 0.0312 to 4 μg mL−1and from 0.0625 to 1 μg mL−1 for... |

| Abstract This study aimed to evaluate the in vitro antifungal activity of terpinen-4-ol, tyrosol, and β-lapachone against strains of Coccidioides posadasii in filamentous phase (n = 22) and Histoplasma capsulatum in both filamentous (n = 40) and yeast phases (n = 13), using the broth dilution methods as described by the Clinical and Laboratory Standards Institute, to determine the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of these compounds. The mechanisms of action of these compounds were also investigated by analyzing their effect on cell membrane permeability and ergosterol synthesis. The MIC and MFCf these compounds against C. posadasii, mycelial H. capsulatum, and yeast-like H. capsulatum, were in the following... |

| The present study aimed to 1) determine the colonization rates of medically important Trichosporon species on normal perigenital skin and 2) determine the isolation rates of Trichosporon spp. isolated from the urine and catheters of Brazilian patients hospitalized in the Intensive Care Unit (ICU). The overall colonization rate of Trichosporon spp. was 11.15% (112 isolates). The most common species isolated from normal perigenital skin was T. cutaneum (29.46%), followed by T. asteroides (20.53%), T. ovoides (15.17%), T. inkin (10.71%), T. mucoides (8.92%), and T. asahii (6.25%). From urine and catheters, T. asahii was the species most commonly isolated (76.5%; n =23), followed by T. inkin (16.6%; n = 5) and T. asteroides (6.6%; n = 2). In addition, the... |
