Species in this genus are tetrasporocystic, dizoic, lack Stieda bodies and have sporocyst walls consisting of two valves joined by a longitudinal suture.
22.
A sporocyst sac forces its way into the snail's eye stalks, and pulsates at high speed, enlarging the tentacle in the process.
23.
After post-ingestion hatching or penetration of the snail, the miracidium metamorphoses into a simple, sac-like " mother sporocyst ".
24.
The problem here is that these birds do not eat snails, so the sporocyst must find some way of manipulating its future host into eating it.
25.
The mother sporocyst undergoes a round of internal asexual reproduction, giving rise to either " rediae " ( sing . redia ) or " daughter sporocysts ".
26.
The water snail is the first intermediate host in which a miracidium ( an embryonated egg discharged in stool ) goes through its developmental stages ( sporocyst, rediae and cercariae ).
27.
"Goussia " ( Labbe 1896 ) : These species are tetrasporocystic, dizoic, lack Stieda bodies, and have sporocyst walls consisting of two valves joined by a longitudinal suture.
28.
One month-or more with cooler ambient temperatures-after a miracidium has penetrated into the snail, hundreds to thousands of cercariae of the same sex begin to be released through special areas of the sporocyst wall.
29.
This genus and family was created in 1984 for the species " Eimeria funduli " because of morphological differences in the sporocyst suggested that it was not a typical member of the genus " Eimeria ".
