On per-oral vaccination, Salmonella invades and multiply in the mucosa-associated lymphatic tissues (MALT) and gut-associated lymphatic tissues (GALT) such as Peyer’s patches. The vaccine strain survives and multiplies for a period of time just sufficient for eliciting a protective response.
This characteristic dissemination pattern allows Virsal E strain to stimulate cell-mediated, and secretory antibody immune responses.
