| Popis: | Acanthocephalan parasites were collected from the intestinal tracts of 137 predominantly wild fish (1 barbelBarbus barbus, 3 European chubSqualius cephalus, 13 rainbow troutOncorhynchus mykissand 120 brown troutSalmo trutta) from 12 localities. The condition factor, intensity of acanthocephalan infection and pathological lesions, if applicable, were documented. Routine bacteriology and virology were performed, and the brown trout were additionally tested for the presence of the myxozoan parasiteTetracapsolioides bryosalmonaeby PCR. In total, 113 acanthocephalans were barcoded by sequencing a section of the mitochondrial cytochrome oxidase subunit I (COI) gene. Barcoding of the acanthocephalan tissues resulted in 77 sequences, of which 56 were assigned toEchinorhynchus truttae(3 genotypes), 11 toPomphorhynchus tereticollis(9 genotypes), 9 toAcanthocephalussp. (5 genotypes) and 1 to Neoechinorhynchida. Most of these genotypes were detected for the first time. Statistically, the acanthocephalan infection did not have an impact on the condition factor of the brown trout. Infection withP. tereticolliscaused more severe pathological changes in the digestive tract thanE. truttae. The present study provides new data regarding the distribution of acanthocephalan species in Austria and their impact on individual fish. In addition, new barcoding data from acanthocephalan parasites are presented, and the occurrence ofP. tereticollisin European chub in Austria and in brown and rainbow trout in general was confirmed for the first time. |
