Flashcards in 08 - Cryptosporidium Deck (14):
1

(Cryptosporidia)

1. parasitize what?

2. What kind of parasites (how many hosts)?

3. Where located relative to cell?

1. vertebrates

2. monoxenous

3. epicellular (close proximity but not inside cell)

2

What are the main differences in the repro cycle here?

naked sporozoites (no sporocysts)

oocysts are fully sporulated when excreted

means they are infective immediately

(the stuff in yellow)

3

What are the common 4?

what is the one we really need to know?

how big are cryptosporidum spoes?

parvum, muris, baileyi, meleagradis

parvum (the only one we are going to worry about... so forget about remembering the four)

are always the smallest

4

exactly what we talked about in last two lectures

what is the difference here though?

What is another big difference?

the number of sporozoites (and the fact that they are naked) in the oocyst

all takes place on the surface of the epithelial cells
