ABSTRACT
The oocysts of Caryospora cherrughi sp. n. were described from the feces of the saker falcon, Falco cherrug, collected from the falcon market in Riyadh City, Saudi Arabia. The prevalence of infection was 21.4 % (15/70). The majority of the oocysts examined had completed sporulation within 64-84 h at 24 ± 2 °C. Sporulated oocysts are ovoid in shape, measuring 32.1 × 29.3 (30.7-34.5 × 27.7-29.8) µm; shape index (L/W) is 1.1 (1.04-1.27) µm. The oocyst wall is smooth and bilayered. Micropyle, polar granule, and oocyst residuum are absent. Sporocysts are ellipsoidal, measuring 24.1 × 19.6 (23.0-25.5 × 18.7-20.5) µm; with a smooth single-layered wall, but there is no Stieda body. The sporocyst residuum is present as numerous small granules. Sporozoites are banana-shaped, blunt at one end, and slightly tapered at the other, each with a large single refractile body. C. cherrughi sp. n. is the third caryosporian species described from F. cherrug.

Large numbers of coccidian oocysts belonging to the genus Isospora were obtained from the intestinal contents of ten legless lizards Diplometopon zarudnyi collected from eastern region, Saudi Arabia. The oocysts are spherical to subspherical, 33.3 x 30.9 (28.6-35.2 x 26.8-32.7) microns with a bilayered wall 1.4 (1.3-1.6) microns thick. Micropyle, polar granule and oocyst residuum are absent. The sporocysts are ellipsoid, 20.1 x 13.8 (17.5-22.3 x 12.2-15.4) microns. A sporocyst residuum, stieda and substieda bodies are present. Sporozoites are banana shaped, blunt at one end and tapered at the other and containing spherical anterior and posterior refractile bodies of the same size. Since this Isospora sp. does not resemble, any other species of Isospora previously described from lizards of the genus Diplometopon, it has been named Isospora diplometoponi n.sp. after the host generic name.

Faeces of 228 domestic goats (Capra hircus) from the central region of Saudi Arabia were examined for the presence of coccidian oocysts. Ten species of coccidia were identified and described. A total of 90.3% of the specimens were positive, most of them contained 100-1000 oocysts per g of faecal sample. Kids less than 1 year old had higher oocyst counts than goatlings or adult goats. Mixed infections with three to five species were found in 69.7% of the specimens and six to eight species were found in 10.1%. Eimeria arloingi and E. hirci were most prevalent. E. alijevi, E. ninakohlyakimovae, E. caprina, E. christenseni and E. apsheronica were less common. E. jolchijevi, E. caprovina and E. punctata were relatively rare.

Eimeria gazella Musaev, 1970 is redescribed for the first time from the feces of 3 of 6 Arabian gazelles, Gazella gazella arabica from the Riyadh Zoo in Saudi Arabia. Oocyst measurements were similar to those reported previously from the goitered gazelle, Gazella subgutturosa, in Kazakhstan (USSR). Except for our observation of many small polar granules, and Stieda body, oocyst morphology was identical to the original description of E. gazella.

Oocysts of Eimeria saudiensis n. sp. (Apicomplexa: Eimeriidae) are described from the feces of the Arabian oryx, Oryx leucoryx, from the Riyadh Zoo, Saudi Arabia. The oocysts were ellipsoidal or slightly ovoid, 31.2 x 24.5 (24.3-36.5 x 20.0-27.6) micron with a bilayered wall about 1.7 micron thick. The micropyle was covered by a dome-shaped cap. The oocyst residuum was absent, but tiny polar granules were present. The sporocysts were elongate ovoid, 14.3 x 7.2 (11.5-18.5 x 6.0-9.0) micron, had a Stieda body, but lacked a substiedal body. The sporocyst residuum was present, composed of numerous small granules. The sporozoites were elongate club-shaped, and contained two prominent refractile bodies.

Saudi Arabian camels (Camelus dromedarius) are infected with three species of Eimeria: E. dromedarii (28.4%), E. rajasthani (22.2%), and E. cameli (19.2%); 41.6% of the animals examined were positive. The highest prevalence of infection was reported in the western region of the country. Mixed infection with two Eimeria species is most common; E. dromedarii was most frequently and generally the most predominant species. Eimeria dromedarii and E. rajasthani are described for the first time from Saudi Arabian camels.

The faeces of 205 domestic cattle (Bos taurus) from 5 regions of Saudi Arabia were examined for the presence of coccidian parasites. The following species of Eimeria were recovered: Eimeria auburnensis, E. bovis, E. cylindrica, E. ellipsoidalis, E. subspherica, E. wyomingensis and E. zuerni. A total of 34.1% of the individual faecal samples were positive for the presence of coccidial oocysts. Mixed infections of 2-4 species were found in 15.7% of the specimens. E. zuerni and E. bovis occurred most frequently and were generally the most predominant species. The incidence of coccidia-infected cattle was higher in the eastern region.
