An helminthological investigation of 104 reptile species was carried out in south Moravia (Czech Republic). We examined Lacerta viridis, L. agilis, Anguis fragilis, Natrix natrix, Coronella austriaca and Vipera berus. Twelve species of parasites were found. Among these, Nematoda occurred most often, followed by Trematoda and Cestoda. No Acanthocephala were detected.
