Survival of GBS-S19 in fresh human blood after 20 h growth in the presence of polyols. GBS was grown in TH broth supplemented with polyols and then assayed for the bacteria’s ability to survive in fresh human blood with (a) or without (b) addition of polyols during incubation. Results are expressed as a fold change in percent of survival in comparison to control GBS-S19 grown in TH broth only. Fold change in percent survival is the number of CFU obtained at the end of the incubation period over the number of CFU obtained at time zero multiplied by 100. Y-axis values in (a) and (b) are the same in magnitude to allow direct comparison between the two figures. Significance was determined by comparing test values with control (THB with 0% polyols). An asterisk (*) indicates statistical significance (p < 0.05), (**) indicates (p < 0.01), (***) indicates (p < 0.001) and NS indicates not significant
