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 mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines it is a polysaccharide vaccine that does not confer long-term protection the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time None of these mutations in the viral hemagglutinin may allow the virus to evade the immune response elicited by previous vaccines it is a polysaccharide vaccine that does not confer long-term protection 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 cleavage of rRNA that results in disruption of ribosome function ADP ribosylation of adenylate cyclase that stops production of cAMP ADP ribosylation of a G protein that locks it into an active form that stimulates adenylate cyclase to make cAMP ADP ribosylation of guanylate cyclase that stimulates production of cGMP cleavage of rRNA that results in disruption of ribosome function ADP ribosylation of adenylate cyclase that stops production of cAMP ADP ribosylation of a G protein that locks it into an active form that stimulates adenylate cyclase to make cAMP ANSWER DOWNLOAD EXAMIANS APP
