acquired azole resistance in opportunistic fungi causes severe clinical problems in immunosuppressed individuals. this study investigated the molecular mechanisms of azole resistance in clinical isolates of candida glabrata . six unmatched strains were obtained from an epidemiological survey of candidiasis in immunocompromised hosts that included azole and amphotericin b susceptible and azole r...

The acetone extract of the lichen Ramalina farinacea and its (+)-usnic acid constituent showed antimicrobial activity against Bacillus subtilis, Listeria monocytogenes, Proteus vulgaris, Staphylococcus aureus, Streptococcus faecalis, Yersinia enterocolitica, Candida albicans, and Candida glabrata. Norstictic acid was active against Aeromonas hydrophila as well as the above microorganisms except...

Due to unacceptably high interlaboratory variation in caspofungin MIC values, we evaluated the use of micafungin as a surrogate marker to predict the susceptibility of Candida spp. to caspofungin using reference methods and species-specific interpretive criteria. The MIC results for 3,764 strains of Candida (eight species), including 73 strains with fks mutations, were used. Caspofungin MIC val...

The human pathogenic yeast Candida glabrata is the second most common Candida pathogen after Candida albicans, causing both bloodstream and mucosal infections. The centromere (CEN) DNA of C. glabrata (CgCEN), although structurally very similar to that of Saccharomyces cerevisiae, is not functional in S. cerevisiae. To further examine the structure of the C. glabrata inner kinetochore, we isolat...

results comparative analysis of predicted amino acids in the phylogenetic tree showed high similarity between c. glabrata and s cerevisiae. besides, c. glabrata demonstrated the capability to grow in glucose levels as low as 0.01% in the spot dilution assay. in qrt-pcr analysis, differential expressions were observed in selected genes when c. glabrata was subjected to different glucose concentr...

Thirteen strains of the genus Candida were isolated from catheter, urine and surgical wounds from individual patients of the Santa Casa de Misericórdia, Belo Horizonte, MG, Brazil. Ten strains were characterized as Candida albicans, two as Candida glabrata, and one as Candida parapsilosis. Isolates were evaluated for molecular relatedness by random amplified polymorphic DNA technique using 15 p...

OBJECTIVES Pre-emptive fluconazole (fcz) anti-fungal therapy is often based upon Candida colonisation of at least 2 non-contiguous non-sterile sites. The aim of this study was to evaluate the relationship between candidaemia and prior colonisation of non-sterile sites. METHODS A retrospective observational study was performed in the intensive care unit/high dependency unit (ICU/HDU) of a Univ...

Echinocandins have become the drug of choice in infections caused by Candida glabrata. The objective of this study was to evaluate the in vitro activity of caspofungin alone and in combination against C. glabrata. In vitro assays demonstrated that caspofungin alone showed excellent fungicidal activity against C. glabrata, including fluconazole-resistant strains. The combination of caspofungin a...

OBJECTIVES Novel highly functionalized bis cyclohexenone ethyl carboxylates 7-12 were designed, synthesized and their structures were elucidated by their elemental analysis, MS, FT-IR, one-dimensional 1H, and 13C NMR spectroscopic data. MATERIALS AND METHODS All the synthesized compounds 7-12 were tested for their in vitro antifungal activities against Candida sp. namely Candida albicans, Can...
