Apicomplexan hemoparasites are widespread in reptiles. This project examined different species of lizards and whether or not they carry these unidentified parasites, namely, common side-blotched (Uta stansburiana), desert spiny (Sceloporus magister), and ornate tree lizards (Urosaurus ornatus). We hypothesized that there will be parasites in the species examined. Specimens were captured at multiple sites in Washington County, Utah, and blood samples were obtained. These samples were prepared, then analyzed for parasite presence/absence and osmolality. Possible hemoparasites and irregularities have been found in all three of the species examined. Our goal was to bridge knowledge gaps regarding parasite presence and identification in lizard species in southwestern Utah. Although previous work in this system has assessed the physiological effects of hemoparasites, our next goals are to identify what parasite species are found, and if they are common across host species.
