Abstract:
Candida albicans, a diploid yeast commensal and opportunist pathogen, has evolved unusual mechanisms for maintenance of genetic diversity in the absence of a complete sexual cycle. These include chromosomal polymorphisms, mitotic recombination events, and gains and losses of heterozygosity, superimposed on a fundamentally clonal mode of reproduction. Molecular typing of C. albicans strains shows geographical evolutionary associations but these have become partially blurred, probably as a result of extensive human travel. Individual patients usually carry a single C. albicans strain type, but this may undergo microvariation leading to detection of mixtures of closely related types. Associations have been found between clade 1, the most common multilocus sequence typing cluster of related C. albicans strains, and resistance to flucytosine and terbinafine. There are also clade-related associations with lengths of tandem repeats in some cell-surface proteins, but not with virulence or type of infection.
