Attenuated virulence of chitin-deficient mutants of Candida albicans.
We have analyzed the role of chitin, a cell-wall polysaccharide, in the virulence of Candida albicans. Mutants with a 5-fold reduction in chitin were obtained in two ways: (i) by selecting mutants resistant to Calcofluor, a fluorescent dye that binds to chitin and inhibits growth, and (ii) by disrupting CHS3, the C. albicans homolog of CSD2/CAL1/DIT101/KT12, a Saccharomyces cerevisiae gene requ...
متن کاملCell biology of Candida albicans–host interactions
Candida albicans is a commensal coloniser of most people and a pathogen of the immunocompromised or patients in which barriers that prevent dissemination have been disrupted. Both the commensal and pathogenic states involve regulation and adaptation to the host microenvironment. The pathogenic potential can be downregulated to sustain commensalism or upregulated to damage host tissue and avoid ...
متن کاملCell biology of mating in Candida albicans.
It was recently demonstrated that strains homozygous for either of the mating type-like loci MTLa and MTLalpha of Candida albicans undergo white-opaque switching and that expression of the opaque-phase phenotype greatly enhances mating between strains. Exploiting the latter property to obtain high-frequency mating, we have characterized the cell biology of the mating process of C. albicans. Emp...
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 کاملGenetic analysis of Candida albicans morphological mutants.
In contrast to some other strains, Candida albicans 1001 gave rise, upon UV irradiation, to mutants displaying a 'rough colony' morphology associated with a permanent alteration in morphogenesis which determined growth of the cells mostly as pseudohyphae. One of these mutants, C. albicans 1001FR, could form sectored (rough/smooth) colonies spontaneously, and with increasing frequency by treatme...
