Microorganisms and Disease What is common in catheters and ventilators? Bacteria responsible for associated infections are usually susceptible to antibiotics They predispose patients to viral rather than bacterial infections They bypass important defenses of the body They are used primarily in neonatal intensive care units Bacteria responsible for associated infections are usually susceptible to antibiotics They predispose patients to viral rather than bacterial infections They bypass important defenses of the body They are used primarily in neonatal intensive care units ANSWER DOWNLOAD EXAMIANS APP
Microorganisms and Disease The influenza vaccine is administered each year because it is a polysaccharide vaccine that does not confer long-term protection None of these the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time 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 None of these the vaccine is sufficiently toxic to make it necessary to administer only a small amount at any one time 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 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 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 ADP ribosylation of guanylate cyclase that stimulates production of cGMP ANSWER DOWNLOAD EXAMIANS APP
