In vitro assays demonstrate photoreactivating enzyme activity in extracts of Candida pseudotropicalis but not in extracts of Candida albicans, Candida stellatoidea, or Candida tropicalis.

BACKGROUND Non-antifungal drugs appear promising in treatment of opportunistic infections of Candida spp. that are often resistant to current antifungals. METHODS The broth macrodilution method (NCCLS M27-P document) was used to compare the antifungal activity of trifluoperazine, propranolol, and lansoprazole with that of ketoconazole and amphotericin B, using 50 yeast isolates from the GI tr...

Mixed fungal infection and acquired echinocandin resistance of Candida spp. remain infrequent. In this study we have reported the case of a patient hospitalized for tuberculosis who experienced multiple infections due to three common Candida species (C. albicans, C. glabrata, C. tropicalis). Furthermore, consecutive isolates from blood cultures and heart valve were found resistant to azoles (C....

Candida virulence attributes include the ability to colonize and invade host tissues, and the secretion of hydrolytic enzymes. Although Candida albicans is regarded as the principal fungi causing infections in humans, other species, particularly Candida tropicalis, are increasingly being recognized as human pathogens. Relatively little is known, however, about the virulence attributes associate...

We report here the complete genome sequence of Candida tropicalis no. 121. C. tropicalis no. 121 is a high-RNA-producing strain obtained by mutagenesis in our laboratory. The complete genome sequence was determined using the Illumina HiSeq 2000 and contains 6,415 genes. The genome size of C. tropicalis no. 121 is >15.3 Mb.

Fluconazole disk-diffusion susceptibility was evaluated in 230 blood isolates and 344 non-blood clinical isolates of Candida spp. collected in 2002 at National Taiwan University Hospital. Up to 93.5% of blood isolates were susceptible to fluconazole, 3% were susceptible dose-dependent, and 3.5% were resistant. The minimum inhibitory concentrations at which 50% of tested isolates were inhibited ...

CHROMagar Candida is a new differential culture medium that allows the isolation and presumptive identification of species of yeast of clinical importance. During the past two decades, there has been a significant increase in the prevalence of fungal infections caused by Candida species. The aim of the study was to isolate and identify Candida species from the oral cavity with CHROMagar Candida...

A protocol employing inositol starvation was used to isolate proline and adenine auxotrophs of Candida tropicalis. Interspecific hybrids between red adenine auxotrophs of C. tropicalis and Candida albicans were formed by protoplast fusion. These C. tropicalis red adenine auxotrophs were shown to fall into two complementation groups by crossing them with a known C. albicans ade1 tester strain. I...

Morphogenic conversion of Candida from a yeast to hyphal morphology plays a pivotal role in the pathogenicity of Candida species. Both Candida albicans and Candida tropicalis, in combination with a variety of different bacterial strains and species, appear in biofilms on silicone-rubber voice prostheses used in laryngectomized patients. Here we study biofilm formation on silicone-rubber by C. a...
