Diphtheria toxin and edema toxin are ADP ribosylating toxins Both organisms are gram-positive spore formers The most serious disease symptoms are the direct result of toxin action Both organisms cause skin and respiratory tract infections Diphtheria toxin and edema toxin are ADP ribosylating toxins Both organisms are gram-positive spore formers The most serious disease symptoms are the direct result of toxin action Both organisms cause skin and respiratory tract infections ANSWER DOWNLOAD EXAMIANS APP
Microorganisms and Disease The "A" subunit of diphtheria toxin binds host cell receptors found on heart cells forms cAMP that leads to fluid accumulation cause ADP ribosylation of a factor involved in protein synthesis lysis macrophages with the release of cytokines binds host cell receptors found on heart cells forms cAMP that leads to fluid accumulation cause ADP ribosylation of a factor involved in protein synthesis lysis macrophages with the release of cytokines ANSWER DOWNLOAD EXAMIANS APP
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 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 None of these 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 it is a polysaccharide vaccine that does not confer long-term protection None of these 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 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 cleavage of rRNA that results in disruption of ribosome function ADP ribosylation of guanylate cyclase that stimulates production of cGMP 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 cleavage of rRNA that results in disruption of ribosome function ANSWER DOWNLOAD EXAMIANS APP
