Nematopsis annulipes     (Protozoan)
Organism information awaits expert curation
Taxonomy
Kingdom:Chromista
Phylum:Myzozoa
Class: Conoidasida
Order:Eugregarinorida
Family:Porosporidae

Description
Sporadins: Biassociative, association caudofrontal; color milky-white. Syzygy early, linear; occasionally two satellites in syzygy with a primite.
Primites: Protomerite shape subspherical to ovoid; epicyte uniformly thick, striated; endocyte granular. Septum circular, convex toward deutomerite. Deutomerite narrow behind septum gradually dilates caudally, posterior end broadly round or flat; epicyte longitudinally striated; endocyte granular with a transparent lens-shaped structure at posterior end. Nucleus spherical, variable in position; endosome single, spherical, contains 8-12 granules.
Satellites: Protomerite shape rectangular, broader than long; anterior margin flat; deutomerite shape elongate ovoid, which is widest at the middle; epicyte uniformly thick; endocyte granular. Nucleus and endosome similar to primite.
Association of 3 sporadins: Two satellites in syzygy with a primite. Primite ovoid, measured 151.8; one satellite 87.5 and the other satellite 102.3 in length.

Gametocysts: Shape spherical to ovoid; color milky-white; cyst wall single, hyaline.
Gymnospores: Shape spherical, uninucleated bodies arranged radially in a rosette pattern around a central, hyaline cytoplasm.
Trophozoites: Development extracellular. Smallest observed trophozoite narrow, elongate ovoid.

Type host: Uca annulipes Edwards
Site of infection: Intestine
