Karyological analysis of (Echinorhynchida): expanding the cytogenetic knowledge in acanthocephalans.

This study presents the first comprehensive cytogenetic analysis of the common amphibian parasite . A combination of classical cytogenetic methods and molecular techniques, including the fluorescence in situ hybridization (FISH) mapping of ribosomal and histone H3, was conducted. The karyotype consisted of three metacentric autosomes and either one submetacentric X chromosome in males or two submetacentric X chromosomes in females, resulting in a chromosome number of 2n = 7/8 (male/female).

Acanthocephalans from freshwater fishes in northeast Thailand with the description of a new species of the subgenus Verma & Dutta, 1929 (Acanthocephala, Quadrigyridae).

During an ichthyoparasitological survey in northeast Thailand in 2015, four species of acanthocephalans were found in four species of freshwater fishes. Adult stages of Wongkham & Whitfield, 1999 and sp. (Eoacanthocephala, Quadrigyridae) were collected from (Anabantiformes, Channidae) and (Siluriformes, Bagridae), respectively, and cystacanths of sp.

Helminths found in common species of the herpetofauna in Ukraine.

Background: Only a few comprehensive studies have been carried out on parasites in amphibians and reptiles in Ukraine. This has resulted in identifying over 100 helminth species across these vertebrate groups. However, most of the studies were performed in the 20 century and the taxonomy of many parasites and their hosts has changed ever since, in addition to the discovery of new species and registrations of species that had not been previously known for Ukraine.

A study of the endohelminths of the European perch L. from the central region of the Danube river basin in Slovakia.

The European perch L. serves as a host of different endohelminths of Trematoda, Cestoda, Nematoda, and Acanthocephala. Its natural range covers freshwater basins throughout much of Europe, including the Danube.
