Subclass Telosporidia is a group of parasitic protists that belong to the phylum Apicomplexa. Parasites in this subclass are characterized by producing small, round, and spore-like structures called telospores. However, telospores are not the only distinctive feature of this subclass. Some other synonyms used to describe Subclass Telosporidia include the following: - Telosporidian parasites - Apicomplexan organisms with spherical-shaped spores - Telosporidia class of parasitic protozoa - Apicomplexa subclass with distinctive spores - Telospore-forming Apicomplexans. The diversity of parasites within this subclass is impressive, as there are numerous genera that exhibit a range of complexities in their life cycles, host relationships, and symptoms caused by infection.
