SUMMARY
This study was carried out in order to identify the different parasites (ecto and mesoparasites) infesting the tortoise Testudo graeca graeca. For this, a population of 24 tortoises was studied from mid-March to May 2018, in the region of Aflou-Laghouat, within two sites: Djellel and Oued Sebgag. The turtles were captured at the time of their activity; sex, age, body weight, total length of the shell and body height were determined. A careful search for parasites has been carried out using various recommended techniques. A total of 126 Hyalomma aegyptium ticks were identified, with an overall prevalence of 71%, an average intensity of 7.4 and an abundance of 5 ticks per individual. The stool examination identified six mesoparasites, namely: Angusticaecum holopterum, Enterobius vermicularis, Strongylus sp, Nematodirus sp, Trichostrongylus sp, Fasciola hepatica. The sex of the host showed a significant influence on the parasitic infestation: the females were four times more infested than the males.
