Morphological forms of Trypanosoma evansi from blood of Arabian camel [Camelus dromedarius] in the Riyadh metropolitan areas

Trypanosoma evansi is commonly referred to as haemoflagellate infesting camels and other vertebrates. It is causative agent of number of diseases. T. evansi has several morphological forms. We have detected three forms in the blood of camels, slender, transitional and intermediate. The present study is the first investigation on the morphological forms of T. evansi in Arabian camels in Saudi Arabia

Eimeria gazani N. SP. [apicomplexa: eimeriidae] from the lizard, scincus hemprichii [Sauria: Scincidae] in Saudi Arabia

Eimeria gazani n. sp. was described from the intestine of the lizard, Scincus hemprichii captured at Gazan, western region. Sporulated oocysts ovoidal 23.5x19.7 [20.8-25.0 x19.0-21.2] micro m, with smooth brownish-green bilayered wall. Micropyle present, covered by a dome-shaped cap. Oocyst residu-um and polar granule are present. Sporocysts ellipsoidal, 10.8x6.9 [10.0-11.4x6.1-7.4] micro.m., with a prominent Stieda body. Sporocyst residuum present, sporozoites elongate, laying head to tail in sporocysts, each with large and small subspherical refractile globule

Eimeria hemprichii N. SP. [apicomplexa: eimeriidae] from the lizard, scincus hemprichii [sauria: scincidae] in Saudi Arabia

Eimeria hemprichii n. sp. was described from the gall bladder of the lizard, Scincus hemprichii captured at Gazan Province, western region, Saudi Arabia. Sporulated oocysts are ellipsoidal, 34.6x2 1.4 [32.5 - 36.3 x 20.7 - 22.5] micro m. with smooth greenish-yellow bi-layered wall. Micropyle, polar granule and oocyst residuum are absent. Sporocysts are ellipsoidal, 11.6 x 8.0 [11.2-12.6 x 7.5-8.4] micro m. Sporocyst residuum is present, but without stieda or substiedal bodies. Sporozoites are elongate, laying head to tail in sporocyst and each one contains a single spherical posterior re-fracttile body

Eimeria pipistrellus n. sp. from Pipistrellus kuhlii (Chiroptera: Vespertilionidae) in Saudi Arabia

Fecal samples from 12 Pipistrellus kuhlii captured at Shagrah, Saudi Arabia, were examined for coccidia and three (25%) found to harbor a undescribed eimerian, herein described as Eimeria pipistrellus n. sp. Sporulated oocysts were subspherical, 24.8 x 23.2 (22-27 x 20-25) microns, with a bilayered and smooth wall. The micropyle was absent, but a large oocyst residuum and a single polar granule were present. Sporocysts were ovoid, 11.6 x 8.3 (10.5-13 x 7.5-9) microns, with a prominent Stieda body, but without a substiedal body; sporozoites lay head to tail in sporocysts and contained one large posterior refractile body. Eimeria pipistrellus n. sp. is the 3rd species of the genus Eimeria found from bats of the genus Pipistrellus.
