Species

Spirocystis nidula

Spirocystis is a genus of parasites in the phylum Apicomplexa. The genus was described in 1911 by Léger and Duboscq. [1]

The family Spirocystidae was created in 1915 by Leger & Duboscq in 1915 for this genus. [1]

Description

Species in this genus infect the blackworm ( Lumbriculus variegatus). The asexual forms, crescentic or spiral shaped, may be found in virtually any tissue of the host.

The multinucleate vermicular meronts are ~35  μm in length and occur in the coelomic cavity and various tissues of the host.

The microgametocytes and macrogametes form in the intestinal epithelium. The microgametes are non-flagellated.

The zygote produces a thick walled oocysts ~35 μm in diameter.

The sporoblasts give rise to a single naked sporozoite with a length of up to 40 μm.
