Pathology and Immune Response

Figure 1-Pathogenesis model of Salmonella enterica serovar Typhimurium The bacteria begins the process with attachment to intestinal epithelium (1) via adhesins, followed by invasion, and then engulfment of bacteria (2,3). Salmonella is localized inside the SVC once inside the cytoplasm, where it replicates (5). SVC's trancytose to the basolateral membrane and release the internal cells to the submucosa (6) where they are internalized inside of phagocytes (7), followed by subsequent dissemination by the bloodstream.
