Microorganisms and Disease Type III secretion systems are used to inject "effector" proteins directly into a host cell. Salmonella uses a type III secretion system to help the pathogen to survive within macrophages survive the acid pH of the stomach secrete LT (heat labile toxin) and ST (heat stable toxin) into the lumen of the intestine activate T cells to proliferate and secrete cytokines survive within macrophages survive the acid pH of the stomach secrete LT (heat labile toxin) and ST (heat stable toxin) into the lumen of the intestine activate T cells to proliferate and secrete cytokines ANSWER DOWNLOAD EXAMIANS APP
