title: [Evolution and phylogeny of coccidia with the eimerian-type and isomeric-type oocysts].
abstract: The isosporan-type of oocysts is a later evolutionary purchase in comparison with the eimerioran-type construction of oocysts'. Identical number of sporocysts and sporozoits in the oocysts, bivalvular constructions of sporocysts, heteroxenous life cycles and endogenous sporulation in a group series of coccidia have arisen asynchronously and independently. The evolution of RNA genes and a type of oocysts construction was proceeded in different species of the isosporan-type coccidia and with different velocities.
