Microorganisms and Disease The influenza vaccine is administered each year because the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time None of these it is a polysaccharide vaccine that does not confer long-term protection mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time None of these it is a polysaccharide vaccine that does not confer long-term protection mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines ANSWER DOWNLOAD EXAMIANS APP
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 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 the acid pH of the stomach survive within macrophages 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 the acid pH of the stomach survive within macrophages ANSWER DOWNLOAD EXAMIANS APP
