Figure 5. System dynamics in the presence of probiotics.

Figure 5

Health or disease states are predicted as parameter Inline graphic is varied: Inline graphic (red), Inline graphic (green), Inline graphic (blue), Inline graphic (black), and Inline graphic (dashed). The system is simulated in the bistable region, with initial pathogenic bacteria insult Inline graphic cells/g, pathogenic bacteria growth rate Inline graphic hInline graphic, and probiotic bacteria growth rate Inline graphic hInline graphic. (A) Bacteria in lumen, Inline graphic. (B) Probiotic bacteria in lumen, Inline graphic. (C) Permeability, Inline graphic. (D) Bacteria in blood/tissue, Inline graphic. (E) Probiotic bacteria in blood/tissue, Inline graphic. (F) Immune cells, Inline graphic. (G) Total bacteria in lumen, Inline graphic. (H) Product of luminal bacteria and permeability, Inline graphic. (I) Difference between product in (H) and threshold, Inline graphic.
