title: Two new species of Eimeria (Apicomplexa, Eimeriidae), from local chickens (Gallus domesticus) in Saudi Arabia.
abstract: In this study, two new species of Eimeria parasitizing domestic fowl (Gallus domesticus) are described. Species data were recorded as follow: Eimeria jeddahensis sp. n. with ovoidal occysts 23.5-29.2 x 17.5-22.4 (25.78 +/- 0.357 x 20.32 +/- 0.33) microns, with smooth single layered wall; bilobed polar granule and micropyle present. Sporocysts elongated ovoidal 10-13.5 x 6.3-8.0 (12.03 +/- 0.135 x 7.10 +/- 0.070) microns with a thick, knob like Stieda body and residuum. Eimeria waeli sp. n. with ellipsoidal oocysts 26.5-31.0 x 23.5-27.0 (28.30 +/- 0.327 x 25.30 +/- 0.278) microns with a double-layered wall; polar granule and micropyle present. Sporocysts ovoidal 13.5-16.0 x 7.0-9.5 (14.67 +/- 0.135 x 8.32 +/- 0.162) microns with distinct Stieda body and residuum. The host bird belongs to order Galliformes.
