Eimeria griseus m sp [apicomplexa: emeriidea] from the gray monitor, varanus griseus in Saudi Arabia

ABSTRACT

Eimeria griseus n. sp. is described from the gallbladder of the gray monitor, Varanus griseus. The sporulated oocysts are ellipsoid in shape, measuring 32.8 x 23.0 [30.0-38.3 x 20.0-25.0] mum with smooth yellowish bi-layered wall, 1.2 [0.9-1.3] mum thickness. Micropyle, polar granule and oocyst residuum are absent. Sporocysts are ellipsoid, measuring 11.8 x 8.5 [10.7-12.6 x 7.5-9.0] mum. Sporocyst residuum is present. Sporocysts lack a Stieda body. Sporozoites are banana-shaped blunt at one end and slightly tapered at the second. Eimeria species from Varanus hosts were compared in this study
