your _____ protects your SHiN
spleen
what is the major virulence factor for STr. Pyogenes
M Protein
M Protein mimmicks
myosin, leads to rheumatic heart disease and glomerulonephritis
the bkey virulence factor of staphylococcus aureus is
Protein A
what does protein A do
binds Fc portion of IgG (inhibits phagocytosis)
which is more toxic endo or exotoxins
exotoxins
which produces fever endo or exotoxins
endotoxins
when is LPS released
when bacteria die
which kind of bacteria have porins
gram negative
what are the two classic endotoxin reactions
gram negative sepsis
meningococcemia
what does the A component of an exotoxin do
active/toxic
diptheria has the same mechanism as
pseudomonas aeroginosa (inactivates EF-2 by adding ADP-ribose)
shigella has the same mechanism as
EHEC
what does corynebacterium diptheria look like
thick gray throat/nose
what does shigella cause
bloody diarrhea
what is the difference in the mechanism between shigella and EHEC
in EHEC the shiga-like toxin does the damage
what us the bacterial toxin mechanism of bacillus anthracis
edema factor
vibrio choler and _____ have the same mechanism
ETEC
what are the two toxins in anthrax
edema toxin and lethal toxin
what is also known as travelers diarrhea
ETEC
what two toxins does ETEC produce
Heat Labile Toxin (activates cAMP)
Heat Stable Toxin (activates cGMP)
The heat Labile Toxin in ETEC functions similar to the
cholera toxin
