We assessed the accuracy of species-level identification of two commercially available matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) systems (Bruker Biotyper and Vitek MS) and two conventional phenotypic methods (Phoenix 100 YBC and Vitek 2 Yeast ID) with that of rDNA gene sequencing analysis among 200 clinical isolates of commonly encountered yeast...

The increasing incidence of candidiasis and antifungal resistance as well as the introducing of new antifungal has recently encouraged performing of fungal susceptibility testing. The aim of this study was to evaluate the susceptibility profile of Candida species isolated from patients admitted to Yazd central laboratory to fluconazole. We used the broth microdilution method to evaluate the sus...

Abstract The Urmia Lake National Park (NW Iran) represents a unique ecosystem owing to special ecological conditions prevailing the region. The Urmia Lake National Park comprises a range of normal to extreme environments, with variable range of salinity between 120-300 g/L. The present study was aimed to characterize ascomycetous yeast mycobiota inhabiting hypersaline soils in this region. Soi...

In [1], Alford et al. compared the performances of two Genetic and Evolutionary Methods (GEMs) for multibiometric feature selection and weighting. In this paper, we present two hybrid feature weighting/selection GEMs. Our results show that the hybrid GEMs outperform the GEMs presented in [1], using significantly fewer features while achieving practically the same recognition accuracy.

A total of 750 clinical yeast isolates were evaluated by two identification systems, VITEK 2 and RapID Yeast Plus, using sequence analysis of the rRNA gene internal transcribed spacer regions as the reference method. The VITEK 2 and RapID systems correctly identified 737 (98.2%) and 716 (95.5%) isolates, respectively.

Potential methane-oxidizing-plant growth-promoting yeast was isolated and characterized during 2017-18 at the ICAR-Indian Agricultural Research Institute, New Delhi. Yeast isolates belonging to genus Meyerozyma guilliermondii were from five major flooded paddy growing regions of India. Among all isolates, KAS-143 efficiently oxidized methane up 57.64% ± 0.83 in 6 d under vitro conditions. It al...

A novel approach for the assessment of adherence of Candida albicans to translucent acrylic material is described. The method uses the inverted microscope to visualise yeast adhering to acrylic surfaces while the test material remains immersed in buffer. Adherent cells were not subjected to surface tension forces that can occur during drying processes, so that an even distribution of yeast with...

background: candida parapsilosis is an emergent agent of invasive fungal infections. this yeast is one of the five most widespread yeasts concerned in invasive candidiasis. c. parapsilosis stands out as the second most common yeast species isolated from patients with bloodstream infections especially in neonates with catheter. recently several reports suggested that its reduced susceptibility t...

The screening of antimicrobial activity against Gram-positive bacteria, Gram-negative bacteria, yeast and fungi was carried out on isopropanol extracts prepared from 121 isolates of endophytic fungi isolated from medicinal plants in Malaysia. Sensitivity was found to vary among the microorganisms. Bacillus subtilis, Saccharomyces cerevisiae and Alternaria sp. were susceptible to extracts from t...

CHROMagar Candida is a differential culture medium for the isolation and presumptive identification of clinically important yeasts. Recently the medium was reformulated by Becton Dickinson. This study was designed to evaluate the performance of the new formula of CHROMagar against the original CHROMagar Candida for recovery, growth, and colony color with stock cultures and with direct plating o...
