Saiga antelope and Turkmenian kulans are considered critically endangered and near threatened, respectively, by the International Union for Conservation of Nature (IUCN). Due to these species' fragile status, it is important to understand the pathogens infecting their remaining populations. A total of 496 faecal samples were collected from Ural saiga antelope in western Kazakhstan during June, September, and November of 2021 and May and August of 2022 and 149 faecal samples were collected from kulans in the Altyn-Emel nature reserve in south-eastern Kazakhstan from June to August of 2021. Additionally, endo- and ecto-parasites were collected from 17 saiga that were found deceased due to natural causes. Nine helminths (3 cestodes, 6 nematodes) and two protozoans were found in Ural saiga antelope. In addition to intestinal parasites, one case of cystic echinococcosis due to Echinococcus granulosus infection and one case of cerebral coenurosis due to Taenia multiceps infection was identified on necropsy. None of the collected ticks (all Hyalomma scupense) were found positive for Theileria annulate (enolase gene) or Babesia spp. (18 S ribosomal RNA gene) via PCR. Three intestinal parasites (Parascaris equorum, Strongylus sp., and Oxyuris equi) were found in kulans. All identified parasites, in both saiga and kulans, are also found in domesticated livestock, suggesting a need for better understanding of how parasites are maintained within and between regional wild and domestic ungulate populations.
