|Abstract:||The internal transcribed spacers (ITS-1 and ITS-2) of the ribosomal RNA gene of Pomphorhynchus laevis (Zoega in Müller, 1776) (Acanthocephala) isolated from various fish species across Central and Southern Europe were compared with those of P. lucyi Williams & Rogers, 1984 collected from the largemouth bass Micropterus salmonoides Boulenger from the USA. The nucleotide sequences of ITS regions of P. laevis from minnows Phoxinus phoxinus (L.) and chub Leuciscus cephalus (L.) from two distant localities in the Slovak Republic were found to be 100% identical. The ITS-1 and ITS-2 of P. laevis from chub from the Czech Republic and Italy were also mutually identical, but significantly different from Slovak worms (88.7% identity for ITS-1, 91.3% identity for ITS-2). A fifth sample collected from Barbus tyberinus Bonaparte from Italy was very similar to the sympatric Italian isolate from chub, possessing four nucleotide substitutions in ITS-1 (98.4% identity). The ITS rDNA sequences of P. lucyi differed significantly from those of P. laevis; the values of identity were 51.8-56.1% for ITS-1 and 63.1-65.3% for ITS-2, and were significantly higher than the range of P. laevis within-species variability. The results based on the ITS sequences confirmed the occurrence of strains in P. laevis from Continental Europe which are well defined by molecules but reveal only slight differences in their morphology.|
