A futile act? Thoughts on the reproductive biology of Candida albicans

Abstract

Recent laboratory experiments challenge the long-held view that Candida albicans is asexual and suggest that sexual recombination could occur outside the laboratory and be part of the reproductive strategy of the species. Population genetics studies, however, find little evidence, among clinical isolates, of the recombinant lineages the sexual cycle should generate. A possible explanation of these results is that the progeny of sexual recombination cannot compete with asexually propagating lineages, challenging the widely-held idea that sexual recombination is superior to asexual propagation.
