| molluscs interfering with the capacity of fasciola hepatica miracidia to infect lymnaea truncatula. | fasciola hepatica miracidia labelled with radioselenium were used to study aspects of their host-finding capacity by determining radioactivity subsequently taken up by exposed 'target' snails (lymnaea truncatula). possible interfering effects exercised by a number of non-host snails and bivalves were examined in linear test channels. the infection rate (radioactivity) among 'target' snails was markedly lowered when non-host lymnaea species (l. pereger, l. palustris, l. stagnalis) were interposed ... | 1976 | 980539 |
| a study on snail location by fasciola hepatica using radioisotopically labelled miracidia. | a number of common freshwater molluscs were exposed to fasciola hepatica miracidia labelled in vivo with radioselenium. radioactivity was rapidly incorporated in all lymnaeid species tested (l. stagnalis, l. tomentosa and l. truncatula) whereas no radioactivity could be demonstrated in non-lymnaeid pulmonate species (aplexa hypnorum, physa acuta, physa fontinalis, anisus vortex, gyraulus albus and planorbis planorbis) or in the prosobranchs valvata cristata and valvata piscinalis. however, the p ... | 1976 | 1264488 |
| re-validation of echinostoma miyagawai ishii, 1932 (digenea: echinostomatidae) on the basis of the experimental completion of its life-cycle. | the life-cycle of echinostoma miyagawai, a eurasian species closely related to e. revolutum, was completed in the laboratory, and the morphology of the larval stages and the adults obtained experimentally was studied. planorbis planorbis and anisus vortex were the first intermediate hosts in the brackish lake durankulak on the bulgarian black sea coast. characteristic features of the cercaria include: a prominent collar with 37 spines; a tail as long as the body and with seven conspicuous fin-fo ... | 2000 | 10743854 |
| [the studies of the invasion of alaria alata (goeze,1782) in the province of kuyavia and pomerania]. | the studies were conducted between 1999 and 2001 in two hunting regions. larval alariosis was revealed in the boars only in one of the studied regions. in this region, the results of the parasitological studies, conducted towards a. alata in the direct host (domestic dogs) and indirect hosts (snails: planorbis planorbis and anisus vortex as well as frogs: rana temporaria and rana terrestris) were also positive. the lack of the host snails a. alata in the other region might have resulted from no ... | 2001 | 16894758 |
| bird schistosomes in planorbid snails in the czech republic. | bird schistosomes have been in focus as causative agents of cercarial dermatitis of humans in the last years; however, our knowledge of their species spectrum and intermediate host specificity is still insufficient. our study focused on bird schistosomes developing in planorbid snails that have been less studied so far. from 2001 to 2010, cercariae of bird schistosomes were found in four snail species (gyraulus albus, segmentina nitida, anisus vortex and planorbis planorbis) from seven localitie ... | 2011 | 22079682 |
| detection of planorbis planorbis and anisus vortex as first intermediate hosts of alaria alata (goeze, 1792) in natural conditions in france: molecular evidence. | alaria alata (goeze, 1792), a trematode that parasitizes canids, usually needs two intermediate hosts to complete its life cycle: an aquatic freshwater snail and an amphibian. although many studies have been undertaken on the wild boar's role as paratenic host, owing to the potential threat to human health, few have sought to identify the snails that act as first intermediate hosts in natural conditions. adopting a molecular approach, with specific markers for a portion of the second internal tr ... | 2012 | 22795938 |
