Invasion of HeLa cells by GBS-S19 after growth in 1%, 2% or 4% erythritol, sorbitol, mannitol. Intracellular CFU were recovered after 2 h of infection and were expressed as percent invasion. Internalized GBS grown in 0% polyols were 100-150 CFUs per monolayer. Bars represent the average values obtained from three independent experiments compared with the value obtained from (0%) to determine statistical significance; an asterisk (*) indicates statistical significance (p < 0.05), (**) indicates (p < 0.01) and NS indicates not significant
