Sketchy: Cryptosporidium Flashcards
The _____ then attach to the intestinal wall to cause diarrhea.
sporozoites
Cue:
- multifaceted amethyst gems scattered throughout the water
- multifaceted = cysts are composed of 4 motile sporozoites
- amethyst = acid fast stain makes organism look like amethyst gems on microscopy
Cryptosporidium is a _______ that causes ______ in immunocompromised pts.
parasite; diarrhea
Cue:
- brown water
watery diarrhea
What does Cryptosporidium cause in immunocompetent patients?
mild, watery diarrhea
Cryptosporidium is usually associated with the ____, but it can cause colitis, too.
small intestine
Cue:
- man wearing a pink poncho
pink poncho = acid fast staining
What is the tx for Cryptosporidium caused by Cryptococcus?
- nitazoxanide
- spiramycin (a macrolide)
- supportive
How is Cryptosporidium diagnosed?
positive acid fast staining on stool O&P
Cue:
- small, narrow, smooth pipe attached to the wall, spilling its contents
- small, narrow, smooth pipe = small intestine (no haustra)
- attached to wall = sporozoites attach to intestinal wall
- spilling contents = diarrhea
Cue:
- knitted sock
- nitazoxanide = tx
- filtering water removes oocysts
How is Cryptosporidium prevented?
filtering water
Cryptococcus creates _____, which are released in the feces and then can be transmitted fecal-orally.
oocysts
Cryptosporidium is a parasite that causes diarrhea in _______ pts.
immunocompromised
How is Cryptococcus transmitted?
fecal-oral
Cue:
- bubbles in the water
infectious cysts passed thru the stool
_______ is a parasite that causes diarrhea in immunocompromised pts.
Cryptosporidium
Who is at risk for Cryptococcus?
- people that swim in dirty water
- campers
- people that work with animals
Cue:
- man with a cane
cane = immunocompromised (Cryptosporidium causes diarrhea in HIV/AIDS pts)
Cue:
- spirit crows
spiramycin = tx
What does Cryptococcus cause?
meningitis in immunocompromised
Who can receive nitazoxanide?
immunocompetent pts
