Identification of Spp. in One-humped Camels () from Riyadh and Dammam, Saudi Arabia, via Histological and Phylogenetic Approaches.

spp. are intracellular protozoan parasites that infect birds and animals, resulting in substantial commercial losses. spp. have an indirect life cycle; canines and felines are known to act as final hosts, and numerous domestic and wild animals act as intermediate hosts. The presence of sarcocysts in camel meat may diminish its commercial quality. There is limited knowledge regarding the taxonomy and diagnosis of spp. that infect camels in Saudi Arabia. In this study, transmission electron microscopy (TEM) revealed and () in . This is the first report of in Saudi Arabia and is considered a significant finding. Based on cytochrome c oxidase subunit I gene (COX1) sequences, two samples of spp. isolated from in Riyadh and Dammam were grouped with hosted by in India, hosted by in Norway, hosted by in Italy and hosted by in Canada. The sequences obtained in this study have been deposited in GenBank.
