“…However, this equilibrium may deteriorate when animals are subjected to conditions such as translocation, sequestration, overcrowding or climate change [14]. Intense parasitism can have pronounced impacts on wildlife host populations; it may affect their fecundity, their survival, their growth or even their behavior [15][16][17].…”

This study examined the gastrointestinal parasitological status of three endangered Sub-Saharan antelope species (Addax nasomaculatus, Oryx dammah, Gazella dorcas) hosted at Souss-Massa National Park in Morocco. A total of 254 faecal samples (80 samples from the addax population, 81 from the oryx population and 93 from the dorcas population) were analysed to determine the prevalence and the intensity of the parasites in host faeces (expressed as the mean EPG: egg per gram), using microscopic methods (Flotation and McMaster) and the molecular identification of parasites using PCR and sequencing of the second internal transcribed spacer region of the rDNA (ITS-2). The prevalence results in the addax, oryx and dorcas gazelle were 43.7%, 2.4%, and 61.3%, respectively, for Nematodirus spp.; 21.2%, 12.3%, and 16.13%, respectively, for Trichuris spp.; and 36.2%, 39.5%, and 53.7%, respectively, for other, undistinguished strongylids. The means of EPG values for parasites in addax, oryx and dorcas gazelle were 8.9, 2.4, and 61.3, respectively, for Nematodirus spp.; 4.3, 2.4, and 4.8, respectively, for Trichuris spp.; and 18.1, 16.6, and 50.1, respectively, for other undistinguished strongylids. Sequencing of the ITS-2 rDNA region of the isolated parasites allowed the identification of Camelostrongylus mentulatus and Nematodirus spathiger in these three antelope species. We can conclude that the studied antelopes are infected at tolerating levels with the first record of Camelostrongylus mentulatus and Nematodirus spathiger in those antelopes in Morocco.
