"The basal cestodes have similar attachment organs of a bothriate type. The only exception represents species of Spathebothriidea with a single apical attachment organ only, which indicates the most basal position of these tapeworms among Eucestoda."@en . "1"^^ . "0"^^ . . "Tapeworms are parasitic flatworms adapted to parasitism in the intestine of vertebrate hosts, including man. The phylogenetic relationships of most basal groups of tapeworms have not been clarified even using molecular tools. Therefore, other characters should be found to help in unravelling how these helminths have adapted to parasitic way of life. The principal objective of the proposed project is to detect phylogenetic suitability of morphological characteristics on the anterior part of the body, scolex, because this part is crucial for attachment of cestodes within the host's intestine. There have been described several types of fixation structures. However, their possible homology and morphology have not been subjected to a detailed comparative analysis, which should be the aim of the present project. The data to be obtained should help considerably in mapping individual steps of cestode evolution in relation to the adaptation of scolex structure to attachment within vertebrates."@en .
