Description:

Faecal samples from the rock hyrax (Procavia capensis jayakari Thomas) were collected from the Ibex Reserve in central Saudi Arabia. Eimerian oocysts, which are believed to represent a new species described here as Eimeria tamimi sp. n., were detected in 40 out of 93 samples. Oocysts were fully sporulated in 24-48 hours at 25 ± 2 °C. Sporulated oocysts of E. tamimi sp. n. were ovoid, measuring 35-42 × 19-25 μm (39 × 23 μm), a length/width ratio 1.5-2 (1.7). Oocyst wall was bilayered and measured 1.5 μm in thickness. Micropyle, oocyst residuum and polar granules were not present. Sporocysts are elongate, measuring 12-18 × 9-12 μm (15 × 10 μm), with a length/width ratio 1.1-1.8 (1.5) prominent Stieda bodies and sporocyst residuum. Experimental infection of two clinically healthy rock hyraxes with sporulated oocysts of E. tamimi sp. n. resulted in shedding unsporulated oocysts 5-10 days post infection. Partial sequences of 18S ribosomal RNA (18S rDNA) and cytochrome C oxidase subunit 1 (COI) regions were amplified using the polymerase chain reaction (PCR) and sequenced. Phylogenetic analysis based on 18S rDNA using maximum likelihood (ML) and Bayesian inference (BI) methods revealed that E. tamimi sp. n. grouped with Eimeria quokka Barker, O'Callaghan et Beveridge, 1988, E. mundayi Barker, O´Callaghan et Beveridge, 1988, E. potoroi Barker, O'Callaghan et Beveridge, 1988 and E. gaimardi Barker, O'Callaghan et Beveridge, 1988 marsupials. Eimerian species have been regarded as a paraphyletic group and the present investigation confirmed the conflict between phenotypic traits, used widely in the classification of this group of parasites., Osama B.
