Description	We examined the composition of telomeres of parasitic worms, representatives of flatworm groups Monogenea and Cestoda Platyhelminthes), and thorny-headed worms (Syndermata: Acanthocephala), by fluorescence in situ hybridization (FISH) with different telomeric repeat probes. Our results show that the (TTAGGG)n sequence, supposed to be the ancestral telomere repeat motif of Metazoa, is conserved in Monogenea (Paradiplozoon homoion) and Cestoda (Caryophyllaeus laticeps, Caryophyllaeides fennica, Nippotaenia mogurndae) but not in Acanthocephala Pomphorhynchus laevis and P. tereticollis). In the Pomphorhynchus species, no hybridisation signals were obtained either with the nematode’ (TTAGGC)n, arthropod’ (TTAGG)n and bdelloid (TGTGGG)n, telomeric probes using the FISH with their chromosomes and Southern hybridization with P. laevis DNA. Therefore, we suggest that parasitic Acanthocephala have evolved yet unknown telomeric repeat motif or different mechanism of telomere maintenance.
