Abstract: This study investigates the prevalence of Sarcocystis spp. infections in livestock in Iraq, aiming to assess the potential risk to public health. Conducted at a slaughterhouse in Thi-Qar governorate from October 2023 to March 2024, the study involved the collection of muscle samples from 150 animals (cattle, sheep, and camels). Samples underwent macroscopic and microscopic examination for parasite presence. DNA extraction and PCR analysis were employed for species identification, with sequencing and phylogenetic analysis used for further confirmation. The prevalence of suspected Sarcocyst spp. infection across different animal species. The data prevalence of suspected Sarcocystosis spp. infection in different animals species as (82%,78%,44%) respactly for cattle, sheep and camels of the sampled individuals testing positive for the parasites, while the prevalence of Sarcocystis spp. in infected animals as detected by ribosomal RNA (rRNA) analysis. Across all animal species, the overall prevalence was 72%, with 36 out of 50 samples testing positive for Sarcocystis infection.Statistical analysis was performed to evaluate the association between infection rates and potential risk factors. Results revealed a high prevalence of both Sarcocystis spp. in the studied animals, particularly in cattle and sheep. Specific Sarcocystis species identified included S. tenella, S. cruzi, S. hominis, and S. cameli. The study concludes that these infections pose a significant public health concern in the region, emphasizing the need for effective control measures to prevent transmission.Organ-specific analyses identified high infection rates in intercostal muscles and hearts of cattle, as well as the hearts and esophagus of sheep.
