sporocyst

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
sporocyst /spo·ro·cyst/ (-sist)
1. any cyst or sac containing spores or reproductive cells.
2. a germinal saclike stage in the life cycle of digenetic trematodes, produced by metamorphosis of a miracidium and giving rise to rediae.
3. a stage in the life cycle of certain coccidian protozoa, contained within the oocyst, produced by a sporoblast, and giving rise to sporozoites.

spo·ro·cyst (spôr-sst)
n.
1. A larval form in many trematode flatworms that develops in the body of its molluscan intermediate host.
2. A secondary cyst that develops from a sporoblast and produces within itself one or several sporozoites.

sporocyst
[spôr′əsist]
Etymology: Gk, sporos + kystis, bag
1 any structure containing spores or reproductive cells.
2 a saclike structure, or oocyst, secreted by the zygote of certain protists before sporozoite formation.
3 the second larval stage in the life cycle of parasitic flukes. The saclike organism develops from the miracidium, or first larval stage, in the body of a freshwater snail host and contains germinal cells that give rise either to daughter sporocysts that develop into cercariae or to rediae. See also fluke.

sporocyst [spor´o-sist]
1. any cyst or sac containing spores or reproductive cells; the oocyst of certain protozoa in which sporozoites develop.
2. the larval stages of flukes in snails.

sporocyst
1. any cyst or sac containing spores or reproductive cells; contained in the oocyst of coccidia in which sporozoites develop.
2. the larval stages of flukes in snails.

The eggs hatch in water and go through a series of developmental stages in a snail (miracidium, sporocyst, redia I, redia II, cercaria) and enter the gills, muscles or viscera of fresh-water crustaceans.
Since Cyclospora oocysts must form sporocysts outside the human host before becoming infectious, the filtrate was resuspended in potassium dichromate (2.
Table 1 provides a summary of the model parameters and environmental variables, together with their units, except four parameters associated with snail and sporocyst development, discussed below, which do not appear explicitly in Figure 2.
