Figure 3.
Effect of pre-exposing Salmonella Typhimurium DT104 cells to 18 or 36 mg wood-derived prebiotic/mL (solid gray or black bars, respectively) or to 0.1 or 0.2 M methyl α-D-mannopyranoside (slashed gray or black bars, respectively) per mL exposure medium on quantitative measures of invasion within non-immortalized porcine derived jejunal cell line (IPEC-J2). Control S. Typhimurium DT104 cells pre-exposed to medium alone were recovered at 4.4 × 0.2 log10 CFU/well and are presented as 100% with white bars. Asterisks denote a decrease in invasion (p < 0.05) of the porcine intestinal cells by pre-exposed S. Typhimurium DT104 when compared to controls.
