Résumé :

In Algeria, Emydidae is represented by only one species, the European pond turtle Emys orbicularis (Linnaeus, 1758). A population was studied in the spring of 2013 in the El Kala National Parc. The objective of this study was to identify and quantify the number of leech species. Placobdella costata (Fr. Mûller, 1846) (Hirudinida: Glossiphoniidae) proved to be the only leech species of that was parasite of this Emys orbicularis population. Its prevalence was 50.9%, which was very low at the juvenile stage (14.2%). The intensity (average number of leeches per turtle) was 0.51± 1.20 for this population, but it was lower at the juvenile stage (0.14 ± 0.37). No relationship exists between the parasitic load and the morphological parameters. However, posterior part (hind limbs) had the highest parasite load (57.14 %).
