Crystallospora cristalloides | |
Crystallospora is a genus in the phylum Apicomplexa.
History
The genus Crystallospora was created by Labbé in 1896[1] for a coccidium that Thelohan[2] had discovered in the Atlantic Ocean off France in 1893. The organism was originally called Coccidium cristalloides but Labbe renamed it Crystallospora thelohani.
This species was later transferred to Eimeria by Doflein in 1909.[3]
In 1948 Dogel found the same species in Peter the Great Gulf (Pacific Ocean) off Japan.[4]
Dyková and Lom in 1981 revived this genus because of its unique sporocyst structure.[5]
Taxonomy
There is one species in this genus.
Description
The sporocysts have four sporocysts each with two sporozoites. They are dodecahedral in shape and are composed of two hexagonal, pyrimidal valves joined at their bases by a suture.
