Most common meanings are:
  • Cyst inside oocysts of  Coccidia containing the infectious stages = sporozoites ( Gregarines).

  • Developmental stage of digenean life cycle ( Digenea/Life Cycle) inside the first intermediate host snail. These sporocysts produce depending on the species – daughter sporocysts,  rediae, or  cercariae. The latter leave the snail and may become infectious to a second intermediate host (e.g., in the case of Clonorchis), to the final host (e.g.,  Schistosoma), or are attached at plants to become metacercariae (e.g.,  Fasciola hepatica,  Fasciolopsis buski).
