gross and microscopic pathological changes associated with parasitic infection in european eel (anguilla anguilla, linnaeus 1758).the gross pathological and histopathological changes associated with parasitic infection in the european eel (anguilla anguilla linnaeus, 1758) was investigated. a total of 65 eels collected from three sampling localities in eastern delta, egypt were examined over the period of january-may 2008. the fish were subjected to standard procedures for parasitological and pathological examinations. overall, 22 (33.8%) of the 65 fish examined were found to have parasitic infections. the eels harbored a ...201019953271
trace element concentrations in proteocephalus macrocephalus (cestoda) and anguillicola crassus (nematoda) in comparison to their fish host, anguilla anguilla in ria de aveiro, portugal.the use of some fish parasites as bioindicators of heavy metal pollution has been demonstrated as particularly adequate due to their capacity of bioconcentration. this study evaluated the effect of proteocephalus macrocephalus on the accumulation of trace elements in the edible fish, anguilla anguilla, in a contaminated area in portugal (ria de aveiro). also, the model p. macrocephalus/a. anguilla was assessed as a bioindicator system in the presence of the highly prevalent nematode anguillicola ...200919010518
do eel parasites reflect the local crustacean community? a case study from the rhine river 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
parasite fauna of the eel, anguilla anguilla (linnaeus, 1758), from the polish part of the vistula lagoon.eel is one of the most valuable commercial fish species of the vistula lagoon. for this reason its infection by non-indigenous species of parasites is the subject of the interest of sciencists.200617120993
ultrastructure of the apical glandular region of the scolex of proteocephalus torulosus (cestoda: proteocephalidae).in the apical glandular region of the adult proteocephalus torulosus (batsch, 1786), two types of eccrine gland cells are present. the first type of unicellular gland produces large electron-dense granules of various sizes. the second type contains small electron-dense granules. most cells form glands with large granules; glands with small granules are infrequent. the secretion of both types of gland cells is concentrated in the apical parts of the cyton and in the ducts opening to the exterior. ...200415729946
long-term investigation of the composition and richness of intestinal helminth communities in the stocked population of eel, anguilla anguilla, in neusiedler see, 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
phylogenetic analysis of european species of proteocephalus (cestoda: proteocephalidea): compatibility of molecular and morphological data, and parasite-host coevolution.the phylogeny of european species of the tapeworm genus proteocephalus was studied, based on partial 18s rdna and morphological data. the group was found to be monophyletic. the analysis showed a low informative value of available morphological characters in comparison with molecular data. the morphological matrix resulted in a poorly resolved tree which is, however, compatible with the topology (proteocephalus osculatus (proteocephalus torulosus (proteocephalus macrocephalus, proteocephalus fil ...200111429177
distribution and ultrastructure of two types of scolex gland cells in adult proteocephalus macrocephalus (cestoda, proteocephalidea).in the scolex-neck region of the adult proteocephalus macrocephalus two types of eccrine gland cells are present. the first type of gland cells, localized in the frontal part of the scolex only, contains large, more or less round electron lucid granules. the second type of unicellular glands produces large electron dense granules. these electron dense granular gland cells are localized primarily in the neck region, only few are present in the scolex apex. the secretion of both types of gland cel ...199910229937
on the distribution and abundance of eel parasites in nova scotia: influence of ph.the geographic distribution of metazoan parasites of american eels (anguilla rostrata) was determined from 28 sites in the southern upland and adjacent regions of nova scotia. twelve parasite species were encountered. component community diversity as measured by species richness, shannon-wiener index (h') and hill's number (n1) decreased when ph < 5.4. seven species (azygia longa, crepidostomum brevivitellum, bothriocephalus claviceps, proteocephalus macrocephalus, paraquimperia tenerrima, echin ...19968636841
influence of site, season, silvering stage, and length on the parasites of the european eel anguilla anguilla in two mediterranean coastal lagoons of the island of corsica, france using indicator species method.the parasites of 425 european eels, anguilla anguilla, were studied between 2009 and 2012 in two mediterranean coastal lagoons of the island of corsica, france. an indicator value (indval) method was used for analysis, which combines measures of fidelity and specificity. because of its resilience to detect changes in abundance, indval is an effective ecological bioindicator. the indval method demonstrated that site, season, silvering stage, and length could influence the occurrence of parasite s ...201323739809
temporal and spatial changes in the composition and structure of helminth component communities in european eels anguilla anguilla in an adriatic coastal lagoon and some freshwaters in italy.the composition and diversity of the helminth component communities in eels anguilla anguilla were determined in three separate localities in italy: an adriatic coastal lagoon, comacchio and two freshwater localities, the river po and the lake piediluco. data from comacchio lagoon were analysed over 15 years to determine whether community composition and diversity changed significantly overtime. the community was species rich (nine species, all marine except proteocephalus macrocephalus) and was ...201424135871
