Explanation / Answer

The parasite is: f. Sarcocystis spp. ANSWER

The features
associated with the parasite are:
1) Protozoan genus of parasites,
2) Known to infect mammals primarily
3) Some species even infect reptiles and birds.
4) Life cycle generally involves two host species
5) Sexual reproduction is carried out in the gut of the definitive host (generally a predator). It is later exuded in the solid excretions and ingested by the intermediate host (generally a prey) wherein it enters muscle tissue. Upon eating of prey by predator the cycle is complete.
6) Hence a key characteristic is showing of symptoms only in intermediate host.
