Urospora is a genus of apicomplexan gregarines.[2][3][1]

Characteristics

[edit]

Urospora is a genus of apicomplexans, protists that behave as intracellular parasites. Species of this genus are monocystid gregarines, found in the body cavity or tissues of their hosts: echinoderms, annelids, nemertines and mollusks. They present lateral or frontal syzygies. Their oocysts are heteropolar, with a thin appendage at one end and a transparent conical funnel at the other end.[2] They reproduce through anisogametes, unequal gametes, liberated through the dehiscence of gametocysts by a simple rupture. The oocysts have a well-differentiated wall known as the 'epispore', 8 sporozoites. Each oocyst has an anterior neck and a marked posterior prolongation.[1]
