Toxins Flashcards
what do toxins or poisons do for the bacteria
enhance their virulence
what are the two types of toxins
endotoxin and exotoxin
what toxin causes system wide effects such as fever and shock
endotoxin
what toxin is stable at high heats
endotoxin
what toxin is unstable or heat-labile and denatures at high heat
exotoxin
what toxin is produced but NOT secreted from dead gram - bacteria
endotoxin
what toxin is derived from lipopolysaccharide found in the cell walls of gram - bacteria
endotoxin
what are common side effects of endotoxins
fever and shock
what are the two exceptions to exotoxins that are NOT heat-labile but instead are heat stable
staphylococcal enterotoxin
e coli toxin
toxoids are specific to which toxins
exotoxins
what is a toxoid
a toxin that has been denatured by formaldehyde
what do toxoids do
stimulate immunity
what toxin is tissue specific and affects those tissues in particular
exotoxins
what are 3 exotoxins and their examples of
affecting specific tissues which demonstrates tissue specificity
exotoxin - tissue
tentanospasmin - nerve
botulinin - muscle
diphtheria toxin - connective tissue
beta hemolytic strep contains what enzyme that adds to its virulence
function
streptokinase
dissolves clots which the body uses to wall off the organisms from spreading
