Enteric Diarrhea Bacteria!! Flashcards
locations
small bowel, ileum, colon
location and diarrhea type
SB: watery, ileum: mix water and blood/pus, Colon: blood/pus
four SB bacteria
s. aures, b. ceres, v. cholera, enterotoxigenic E. coli.
SB infections usually mediated by what
toxin! treat with rehydration!
b ceres gram stain
positive
ECEC
pili adhere, multiply, two toxin types
four ileum bacteria
S. NTS, S. Typhi, enterocolitis, campylobacter
NTS
-in other animals, E: uncooked meat, M: small I epithelium (facultative intracellular), s: usually localized, but spreads in immune suppressed. D: submucosa, LPS- some blood/pus
Typhoid
humans only, P-P or F-O
M/s: spreads to liver, spleen, gallbladder
treat: abs (cipro, ceftriaxone)
which have vaccines?
typhoid, cholera
what is campylobacter similar to?
NTS!
what are the three colon bacteria?
shigella dysenteria, enterohemorrhagic e coli, C diff
Shigella dysenteria
E: p/p, f/o, acid resistant, invade M cells
M/S: actin based
Damage: shiga toxin
HUS!
HUS
hemolytic uremia syndrome: hemolytic anemia, thrombocytopenia, renal failure 1 wk after diarrheal phase
EHER
E: fecal beef
M/SL colon epithelium (actin)
Damage : phage releases shiga toxin
