Variation in assimilating functions occurs in spontaneous Candida albicans mutants having chromosomal alterations.
In this study, four clinical isolates and over 100 colony morphology mutants, previously derived spontaneously from strain 3153A during growth on glucose medium, were examined for their utilization of 21 carbon and 3 nitrogen sources at various growth temperatures. The results demonstrated extensive variability in the pattern of assimilation among the mutants and strains, including both the gai...
متن کاملChromosomal variations in Candida albicans.
We report here the separation of chromosomal DNA molecules from the diplokl pathogenic yeast C. albicans by field inversion gel electrophoresls (FIOEK1). Our earlier work on C. albicans ATCC strain 10261 revealed a pulsed field gel electrophoretic pattern of six bands, two of which were possibly doublets (2). In the present study we found that FIGE gave superior resolution with uniform DNA mobi...
متن کاملThe Phenotypic variation of Candida albicans and susceptibility to fluconazole and voriconazole
Candida albicans is the most frequent opportunistic fungal agent in human being. One of its virulence factors is phenotypic switching. In this study, we investigated the susceptibility of different phenotypes of C. albicans, obtained from clinical specimens, to fluconazole (FLZ) and voriconazole (VRZ) with microdilution reference method. In this study, 281 C. albicans of six different phenotype...
متن کاملCandida albicans biofilm-defective mutants.
Biofilm formation plays a key role in the life cycles and subsistence of many microorganisms. For the human fungal pathogen Candida albicans, biofilm development is arguably a virulence trait, because medical implants that serve as biofilm substrates are significant risk factors for infection. The development of C. albicans biofilms in vitro proceeds through an early phase, in which yeast cells...
متن کاملUV and X-ray sensitivity of Candida albicans laboratory strains and mutants having chromosomal alterations.
Utilization of L-sorbose, D-arabinose or primary fluconazole resistance in Candida albicans are controlled by copy number of specific chromosomes. On the other hand, spontaneous morphological mutants have a wide range of chromosomal alterations. We have investigated the UV and X-ray sensitivity of these mutants, as well as C. albicans laboratory strains. While L-sorbose utilizing mutants had no...
