do eel parasites reflect the local crustacean community? a case study from the rhine river system.in 2003, the parasite fauna of 197 european eels anguilla anguilla, captured at three different locations (laufenburg, karlsruhe and beneeden leeuwen) in the river rhine, was analysed. the eels harboured a total of 18 species, among them the protozoa (myxidium giardi, myxobolus kotlani and trypanosoma granulosum), acanthocephalans (acanthocephalus anguillae, acanthocephalus lucii, echinorhynchus truttae, pomphorhynchus laevis), nematodes (paraquimperia tenerrima, pseudocapillaria tomentosa, cama ...200717578598
the cement apparatus of larval and adult acanthocephalus anguillae (acanthocephala), with notes on the copulatory cap and origin of gland secretion.light and electron microscopy were used to investigate the ultrastructure of the cement apparatus, namely cement glands and cement ducts, of mature specimens of the parasite acanthocephalus anguillae (muller, 1780) luhe, 1911 recovered from the alimentary canal of fish leuciscus cephalus (risso, 1826). in addition, the cement apparatus of immature a. anguillae found within the body cavity of the crustacean asellus aquaticus (l.) was examined. in immature and mature males of acanthocephalus angui ...200111355679
cooling water of power plant creates "hot spots" for tropical fishes and parasites.thermally altered water bodies can function as "hot spots" where non-native species are establishing self-sustaining populations beyond their tropical and subtropical native regions. whereas many tropical fish species have been found in these habitats, the introduction of non-native parasites often remains undetected. here, n = 77 convict cichlids (amatitlania nigrofasciata) were sampled by electro-fishing at two sites from a thermally altered stream in germany and examined for parasite fauna an ...201626374537
parasite communities and infection levels of the invasive chinese sleeper perccottus glenii (actinopterygii: odontobutidae) from the naab river basin, germany.the chinese sleeper (perccottus glenii), an invasive asian fish, was first registered in germany in 2009 (westernmost extent of its invasive range). we sampled chinese sleepers from two localities on the bücherlgraben creek (a tributary of the river naab) in south-eastern germany in november 2015 and examined them for parasite infection. twelve taxa were registered, including ciliates (unidentified trichodina), a monogenean, three cestode species, two digenean taxa, two acanthocephalan species, ...201627809946
copulation of acanthocephalus anguillae (acanthocephala).a total of 114 specimens of brown trout, salmo trutta linnaeus, 1758, was sampled by electrofishing between october 1998 and july 1999 from the ceresone stream (north of padua, italy). over 63% of fish were infected with three species of helminth: a tapeworm, cyathocephalus truncatus (pallas, 1781), and two acanthocephalan species, echinorhynchus truttae (schrank, 1788) and acanthocephalus anguillae (muller 1780). on three occasions, in the fore-gut of three brown trout, three pairs of a. anguil ...200010894483
richness and diversity of parasite communities in european eels anguilla anguilla of the river rhine, germany, with special reference to helminth parasites.a total of 121 european eels (anguilla anguilla) from 2 sampling sites on the river rhine were investigated in respect of their parasite communities. special attention was given to the swim bladders, intestines, gills and fins of the fish. twelve different parasite species were found to live in and on the eels. data from each sampling site were kept separate. parasites found in descending order of prevalence were: anguillicola crassus, trypanosoma granulosum, myxobolus sp., paratenuisentis ambig ...199910503258
[helminths in trout (fam. salmonidae) in freshwater reservoirs].a survey is made of the helminths parasitizing in representatives of family salmonidae caught mainly in the free fresh-water basins in the country. more detailed information and study concerned the american and the balkan trout--salmo irideus gairdneri and salmo trutta m. fario respectively--because of their higher economic importance. in the course of the study some corrections were made of the names of some of the species in the light of the new data obtained concerning all helminths alreay me ...19827179733
proteolytic enzymes of pomphorhynchus laevis and in three other acanthocephalan species.cystacanths and adults of the acanthocephalan pomphorhynchus laevis were found to release proteolytic enzymes during in vitro culture. culture media in which cystacanths had been kept contained a trypsinlike collagenolytic proteinase exhibiting a molecular mass of 29 kda on gelatin substrate gel electrophoresis and a ph optimum at ph 9.0. samples of adults possessed a trypsinlike collagenolytic proteinase with a molecular mass of 26 kda and showed a ph optimum at 9.0. leucine aminopeptidase acti ...19948308657

associations and interactions among intestinal helminths of the brown trout, salmo trutta, in northern italy.species co-occurrences and interspecific associations between intensity of infection were studied in helminth communities of three populations of brown trout, salmo trutta, from northern italy. of the eight helminth species, only four were common enough to be included in the analyses: pomphorhynchus laevis, acanthocephalus anguillae, echinorhynchus truttae and cyathocephalus truncatus. the observed frequencies of co-occurrences of the different species, based on presence/absence data, did not di ...200111818049
potential interactions between acanthocephalus anguillae and pomphorhynchus laevis in their natural hosts chub, leuciscus cephalus and the european eel, anguilla anguilla.chub and eels were experimentally infected via intermediate hosts harbouring cystacanths, with pomphorhynchus laevis alone, or acanthocephalus anguillae alone, or simultaneously with mixtures of both species in varying proportions, and sampled at 7, 56 or 112 days post-infection. examination of chub revealed that both species showed low establishment and growth rates, differing markedly from british field data, where chub is apparently one of the most important hosts, and preventing further mean ...19911852495
comparative investigations of the morphology and chemical composition of the eggshells of acanthocephala. ii. palaeacanthocephala.eggshells of the palaeacanthocephalans acanthocephalus anguillae, pomphorhynchus laevis and polymorphus minutus were investigated for their fine structure as well as their chemical composition. the acanthor larvae are surrounded by four eggshells (e1-e4) separated by interstices (g1-g4). immature eggs do not exhibit the complete set of eggshells. the chemical composition of the outermost, thin eggshell (e1) remains unknown. e2 is supplied by outer filaments of different strength; it contains ker ...19921379711
biodiversity of parasites in freshwater environment in relation to pollution.during 1994, 129 specimens of chub (leuciscus cephalus l.) from two localities, polluted--bolelouc, 80th river kilometer, near the city of olomouc, and unpolluted--brodské, 225th river kilometer, near the lanzhot on the morava river, were examined for metazoan parasites. altogether 38 metazoan parasite species including helminths, leeches and glochidia belonging to 14 genera were found, 34 in the case of unpolluted locality (brodské) and 28 in the polluted one (bolelouc). in both localities, 24 ...19979802067
interactions between the acanthocephalans pomphorhynchus laevis and acanthocephalus anguillae in rainbow trout: testing an exclusion hypothesis.rainbow trout were infected simultaneously with cystacanths of the two acanthocephalan species pomphorhynchus laevis and acanthocephalus anguillae in the laboratory. infections consisted of varying proportions of the two species (from 0 to 100%) at low (20 cystacanths) and high (60 cystacanths) levels. fish were sacrificed at 7, 56 and 112 days post-infection (p.i.) and the parasites recovered. at low-level infections there was a high degree of overlap in the range of intestine occupied by the t ...19902362768

does fish reproduction and metabolic activity influence metal levels in fish intestinal parasites, acanthocephalans, during fish spawning and post-spawning period?application of fish intestinal parasites, acanthocephalans, as bioindicators in metal exposure assessment usually involves estimation of their metal levels and bioconcentration factors. metal levels in parasite final host, fishes, are influenced by fish physiology but there is no data for acanthocephalan metal levels. gastrointestinal zn, fe, mn, cd, ag levels in european chub (squalius cephalus l.) from the sava river were significantly higher during chub spawning (april/may) compared to the po ...201425048939
effect of acanthocephalan infection on metal, total protein and metallothionein concentrations in european chub from a sava river section with low metal contamination.in the present study, the importance of considering fish intestinal parasites i.e. the acanthocephalans in metal exposure assessment was estimated under low metal contamination conditions. two acanthocephalan species, pomphorhynchus laevis and acanthocephalus anguillae were examined in 59 specimens of european chub (squalius cephalus l.) sampled at 5 locations along the sava river, croatia. concentrations of essential (cu, mn) and non-essential (ag, cd, pb) metals were higher in intestinal paras ...201323856403
evolutionary anatomy of the muscular apparatus involved in the anchoring of acanthocephala to the intestinal wall of their vertebrate hosts.different conceptions exist regarding structure, function, and evolution of the muscles that move the acanthocephalan presoma, including the proboscis, i.e., the usually hooked hold-fast anchoring these endoparasites to the intestinal wall of their vertebrate definitive hosts. in order to clarify the unresolved issues, we carried out a light microscopic analysis of series of semi-thin sections and whole mounts representing the three traditional acanthocephalan classes: archiacanthocephala (macra ...201728233104
effects of conspecifics and heterospecifics on individual worm mass in four helminth species parasitic in fish.intraspecific and interspecific effects on the growth and body size of helminths are rarely studied in natural situations, yet knowing what determines helminth sizes and thus fecundity is crucial to our understanding of helminth ecology and epidemiology. the determinants of average individual worm mass were investigated in four common species of helminths parasitic in trout, salmo trutta. in the acanthocephalan echinorhynchus truttae, there was a negative relationship between the intensity of in ...200312756550
the parasite community infecting flounders, platichthys flesus, in the tidal thames.the composition of the parasite fauna of the flounder, platichthys flesus, retrieved from two locations in the tidal thames is described in detail for the first time. the combined parasite species list of the flounders from lots road in the upper tideway and west thurrock in the middle tideway consisted of one protozoan (glugea stephani), one monogenean (gyrodactylus sp.), four larval digeneans (cryptocotyle concava, timoniella imbutiforme, t. praeterita, and labratrema minimus), five adult dige ...199910526412
long-term investigation of the composition and richness of intestinal helminth communities in the stocked population of eel, anguilla anguilla, in neusiedler see, austria.data from a long-term study of the intestinal helminth parasite community of eels, anguilla anguilla, stocked into the shallow eutrophic neusiedler see, austria, were collected over an 8 year period (1994-2001). in total, 720 eels from 2 sampling sites were examined. the parasite community showed characteristics similar to those in the natural eel populations in rivers of the uk and mainland europe: it was species poor, with only 5 species (acanthocephalus lucii, acanthocephalus anguillae, raphi ...200515727068
heavy metals concentrations in acanthocephalans parasites compared to their fish host.a number of authors have demonstrated that heavy metal concentrations in intestinal helminths are higher than those found in the tissues of their final hosts. in this work, pb and cr concentrations in the acanthocephalan acanthocephalus anguillae were measured by means of electrothermal atomic absorption spectrometry. the metal concentrations measured in the whole body of acanthocephalans were compared to those in the liver of their fish hosts (leuciscus cephalus) sampled in the lambro river (no ...19989839409
