intermediate host
3 of 15
What type of host does the sexual life cycle occur in
definitive host
4 of 15
what is an intermediate host
Any warm blooded animal that ingests a cyst
5 of 15
in an intermediate host the parasite does not undergo *blank* multiplication in the *blank* of intermediate hosts
sexual, gut

in the intermediate host what causes switching to the slower dividing bradyzoite stage which exists within tissue cysts
the immune system
8 of 15
asexual lifecycle
infection from consuming tissue cyst or oocyst cyst, multiple rounds of fast asexual division (tachyzoites), Tachyzoites transform to Bradyzoites, Bradyzoites divide slowly and from infective tissue cysts
