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.

spo·ro·cyst

(spō'rō-sist),
1. A larval form of digenetic trematode (fluke) that develops in the body of its molluscan intermediate host, usually a snail; the sporocyst forms a simple saclike structure with germinal cells that bud off internally and develop into other larval types that continue this process of larval multiplication (considered to be a form of polyembryony).
See also: miracidium, redia, cercaria.
2. A secondary cyst that develops within the oocyst of Coccidia, a group of sporozoans that includes many of the most important disease agents of domestic animals and fowl; the sporocyst develops from a sporoblast and produces within itself one or several sporozoites, the infective agents for infection and multiplication in the next host.

sporocyst

(spôr′ə-sĭst′)
n.
1. A resting cell that produces asexual plant spores.
2. A protective structure containing the infective sporozoites of an apicomplexan parasite.
3. A saclike larval stage in many trematodes, from which the rediae emerge.

Cercariae are, however, more numerous than miracidia, as each sporocyst can produce thousands of cercariae per day.
The morphologic characteristics of the oocyst, wall, sporocyst, sporozoite, and residual body were determined in micrometers.
Because pancreatic enzymes were essential for excystation of sporozoites from sporocysts. Soya beans consist of proteins that inhibit pancreatic enzymes specifically trypsin thus inhibited coccidial infections (Mathis et al., 2011).
Cotylurus flabelliformis may also penetrate snails of Planorbidae and Physidae, but only if they are infected by other species of trematodes, where its encysts within sporocysts and/ or rediae (Cort, Olivier, & Brackett, 1941).
a) Translucent Stieda body (SB) and sporocyst residuum (SR); b) polar granule (PG) and oocyst wall (OW).
This might be due to the differences in humidity, temperature from place to place (variation in environmental condition), and the weather in Qena Governorate, upper Egypt was dry and hot in general as it supported by that mentioned by Smith and Sherman (1994) who mentioned that hot and humid weather is particularly conducive to sporocyst development and out breaks of clinical coccidiosis.
sporocyst and mother sporocyst, takes place within foot muscles, thereby causing increased empty spaces within muscle fibers after their entry in to the viscera of the snail.
were found under microscope having four sporocysts, each containing two sporozoites.
[6] stated that infestation by sporocysts which are structures of digenetic trematodes could be a threat for host bivalve because of its potential to reduce host fecundity.
Man may be suffering from diarrhea, allergies, abdominal pain, eosinophilic myositis, peripheral blood eosinophilia, bloating, nausea, anorexia, vomiting, difficulty breathing, and pulse becomes severe, caused by eating undercooked meat and coddle, or sporocysts as the final and intermediate host.
The success of infestation was determined by observation under light microscope or dissection of some snails to detect the presence of sporocysts or rediae in the snail's hepatopancreas.
