Microsporidia, Myxozoa, Mesozoa Flashcards
1
Q
Microsporidia
A
- unicellular, obligate, spore-forming
- intracellular (found inside other parasites such as protozoa, platyhelminthes, nematodes, etc.)
- affects honey bees, fish, vertebrates
2
Q
Microsporidia Life Cycle
A
- extrusion of polar filament
- sporoplasm expelled through tube
- merogony/schizogony/asex reproduction in host
- rupture cell and release spores
3
Q
Myxozoan cerebralis “whirling disease”
A
- pierce with polar filament
- multicellular spores with diversity
- gamete and merogony stages
- mostly fish, host specific
4
Q
Microsporidians vs. Myxozoans
A
- polar filaments (myxozoa anchoring function, microsporidians polar tube)
5
Q
Mesozoans
A
- tiny ciliates (own group)
- marine invertebrates
- body two layers of cells, simple sac-like structure
- Dicyemida = cephalopod (squid/octopus)
- orthonectida = stars
