Chronological lifespan and virulence in Candida albicans and other Candida species
In this abstract, chronological lifespan varied widely across Candida species, and caloric restriction extended survival in every species examined. Among 20 clinical Candida albicans isolates, longer lifespan was associated with greater virulence. [1]

Stationary-phase survival across Candida species
The abstract describes chronological lifespan (CLS) as how long yeast cells stay viable after entering stationary phase, a survival trait. The authors note CLS is well studied in Saccharomyces cerevisiae as a model of postmitotic aging, but its relevance to human-associated fungi is poorly understood. Candida species of the CTG clade differ widely in ecology and clinical importance, so the study asked whether stationary-phase survival is linked to pathogenicity across species or among strains.

Caloric restriction extended survival in all species
The study combined an optimized colony-forming-unit-based CLS assay with scalable flow cytometry of membrane integrity across Candida species and genetically diverse Candida albicans isolates. CLS varied extensively across species, yet caloric restriction extended survival in every species examined. This consistent response to reduced glucose occurred despite marked differences in baseline lifespan. Pathogenic species tended toward longer CLS, but long lifespan was not restricted to them: the non-pathogenic C. sojae was among the longest-lived species examined.

Longer lifespan linked to virulence within C. albicans
Among 20 genetically diverse C. albicans clinical isolates, longer CLS was consistently associated with greater virulence. The authors state that the association between CLS and virulence emerges within C. albicans but not across Candida species. They describe the work as establishing a methodological framework for comparative CLS analysis and revealing a broadly shared response to caloric restriction. These are associations in an abstract, not evidence that lifespan causes virulence or that the findings apply to humans.

How to interpret this
This is an abstract; the full text was not reviewed. Design details, exact sample sizes beyond the 20 C. albicans isolates, follow-up and statistical uncertainty are not reported here. The lifespan–virulence link is an association, not causation, and the work concerns yeast cells, not human lifespan.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
