Fig. 5.1 Pathogenesis of Salmonella Typhimurium and Salmonella Typhi. Upon ingestion, Salmonella travel to the small intestine. The bacteria invade Microfold (M) cells and other intestinal epithelial cells through the apical surface to cause infection. (A). Salmonella Typhimurium remains localized in the small intestine and induces an inflammatory host immune response, resulting in bacterial clearance from immunocompetent individuals. (B). Salmonella Typhi escapes from intestinal epithelial cells at the basolateral surface of the intestinal epithelium, enters phagocytes, and evades the host innate immune response, resulting in systemic infection...
