Figure 4

S. typhimurium internalization assay. Untransfected Caco-2 cells were infected with S. typhimurium alone or coinfected with live or heat-killed E. faecium for 4 hours. The number of internalized bacteria was determined by host cell lysis, plating, and counting CFU/well. The data shown are representative of three different experiments ± SD. Error bars represent standard deviations.
