Microorganisms and Disease The influenza vaccine is administered each year because mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines None of these the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time 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 None of these the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time it is a polysaccharide vaccine that does not confer long-term protection 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 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 secrete LT (heat labile toxin) and ST (heat stable toxin) into the lumen of the intestine ANSWER DOWNLOAD EXAMIANS APP
Microorganisms and Disease Cholera toxin is an A-B type toxin in which the B portions bind to a receptor on a host cell and the A portion enters the cell to cause ADP ribosylation of guanylate cyclase that stimulates production of cGMP ADP ribosylation of a G protein that locks it into an active form that stimulates adenylate cyclase to make cAMP ADP ribosylation of adenylate cyclase that stops production of cAMP cleavage of rRNA that results in disruption of ribosome function ADP ribosylation of guanylate cyclase that stimulates production of cGMP ADP ribosylation of a G protein that locks it into an active form that stimulates adenylate cyclase to make cAMP ADP ribosylation of adenylate cyclase that stops production of cAMP cleavage of rRNA that results in disruption of ribosome function ANSWER DOWNLOAD EXAMIANS APP
