| rhipidocotyle fennica (digenea: bucephalidae) from anodonta anatina and pike esox lucius in lithuania. | ribosomal dna sequences of rhipidocotyle sp. adults from esox lucius were shown to be identical to sequences of larval rhipidocotyle fennica, occurring in anodonta anatina in lake vilkokšnis, lithuania. morphological features and host specificity of this adult worm correspond with that, determinate in the first description of r. fennica in finland. these data give the first evidence that a viable population of r. fennica exists in east central europe. bucephalus polymorphus which was reported in ... | 2014 | 25190013 |
| non-native gobies facilitate the transmission of bucephalus polymorphus (trematoda). | introduced species can modify local host-parasite dynamics by amplifying parasite infection which can 'spill-back' to the native fauna, whether they are competent hosts for local parasites, or by acting as parasite sinks with 'dilution' of infection decreasing the parasite burden of native hosts. recently infection by the trematode bucephalus polymorphus has increased in several european rivers, being attributed to the introduction of intermediate host species from the ponto-caspian region. usin ... | 2015 | 26187653 |
| species richness and diversity of the parasites of two predatory fish species - perch (perca fluviatilis linnaeus, 1758) and zander (sander lucioperca linnaeus, 1758) from the pomeranian bay. | pomeranian bay as an ecotone is a transition zone between two different biocenoses, which is characterized by an increase in biodiversity and species density. therefore, pomeranian bay is a destination of finding and reproductive migrations of fish from the rivers entered the area. the aim of the study was to compare parasitic fauna of two predatory fish species from the pomeranian bay, collected from the same fishing grounds at the same period. a total of 126 fish studied (53 perches and 73 zan ... | 2015 | 26342503 |
| Is there a link between shell morphology and parasites of zebra mussels? | The shell morphology of zebra mussels, Dreissena polymorpha, was analyzed to determine if alterations in shell shape and asymmetry between valves were related to its infection status, i.e. infected or not by microparasites like ciliates Ophryoglena spp. or intracellular bacteria Rickettsiales-like organisms (RLOs), and by macroparasites like trematodes Phyllodistomum folium and Bucephalus polymorphus. For microparasites, two groups of mussels were observed depending on shell measurements. Mussel ... | 2011 | 22146241 |
