In Saccharomyces cerevisiae, FLO11 encodes a protein associated with phenotypic traits considered important for virulence. Here, we report the analysis of FLO11 gene expression using RT-LightCycler PCR in several S. cerevisiae strains of different origin (clinical and non-clinical) and with different degrees of in vivo virulence. An association between in vivo virulence and FLO11 expression was observed for the majority of strains when cells were grown at 37 °C in brain heart infusion (BHI) broth to mimic conditions encountered during brain colonization. However, there was a lack of correlation for two of the strains and this was probably due to the loss of a repression sequence in the FLO11 promoter and/or to changes in repetitive sequences in the ORF. The results indicate that the method proposed here, in conjunction with determination of other virulence factors, could usefully predict which S. cerevisiae strains are better suited to colonize in vivo systems.
