| [fatty acid makeup of the cestodes, eubothrium crassum and diphyllobothrium dendriticum]. | the fat-acidic composition of e. crassum and d. dendriticum was investigated. lipids of e. crassum differ in greater unsaturation as compared to these of d. dendriticum as well as in greater amount of acids of type omega 3, whereas acids of type omega 6 and stearic acid were found in extracts of e. crassum in less quantity than in d. dendriticum. this phenomenon is characteristic of organisms living under conditions of low temperatures. | 1979 | 492772 |
| skin the tapeworms before you stain their nervous system! a new method for whole-mount immunocytochemistry. | a new method for making whole-mount immunocytochemical preparations of thick-skinned tapeworms is described. the tough tegument of the worms, which is impermeable to primary and secondary antisera, is removed by placing live worms in distilled water for 5-8 h, during which period the tegument is shed. the worms are thereafter fixed and stained as whole specimens using fluorescence immunocytochemical techniques. both the main nervous structures and the finest neuronal details are revealed by this ... | 1991 | 1924258 |

| [fatty acid composition of the helminths of cold- and warm-blooded vertebrates]. | studies have been made on fatty acid composition of 5 species of parasitic helminthes from fish, birds and mammals. as compared to the lipids from helminthes of endothermic animals (diphylobothrium dendriticum and toxascaris leonina), those from fish parasites (eubothrium crassum, triaenophorus nodulosus and metechynorhynchus salmonis) are less saturated and contain higher amounts of penta- and hexaenic acids, acids of omega 3 type, being less rich in the content of stearic, oleic, dienic and om ... | 1980 | 7468010 |
| [the effect of host temperature on the fatty acid composition of the total and membrane lipids in the cestodes eubothrium crassum and diphyllobothrium dendriticum]. | a comparative qualitative and quantitative analysis of the fatty acid composition of total and lysosome membrane lipids of two cestode species eubothrium crassum (from cold-blooded host) and diphyllobothrium dendriticum (from warm-blooded host) has been carried out. it is shown that quantitative ratio of the fatty acids in the total and membranous lipids of the helminth of cold-blooded host was very similar whereas for the helminth of warm-blooded host fatty acid composition of membranous lipids ... | 1995 | 7483920 |

| [the development of the cestode fauna in rainbow trout (oncorhynchus mykiss) in a newly formed surface mine residual water]. | helminthofaunistical studies on rainbow trout, wild fish and zooplankton organisms of a recently emerged rest waters from an open-cast mine have been made continuously in the period from 1980 till 1990. three years after the beginning of the trout production larval triaenophorosis appeared as the first cestodosis. in the subsequent time changes of the cestode fauna of rainbow trout kept in net-cages could already be observed within a few years. possible causes for the replacement of eubothrium c ... | 1993 | 8508218 |
| establishment, survival and site selection of the cestode eubothrium crassum in brown trout, salmo trutta. | population dynamics, site selection, growth and maturation of the cestode eubothrium crassum in a natural population of salmo trutta in a small lake were studied over a period of 1 year, the life-span of a cohort in fish. infection of fish commenced in spring but peaked in july. small, plerocerciform parasites initially located in the intestine, but then some moved into the pyloric caecae whilst others, the majority in heavy infections, were lost from the fish causing a fall in abundance from 46 ... | 1996 | 8728999 |
| the ecology of endoparasitic helminth infections of brown trout (salmo trutta) and rainbow trout (oncorhynchus mykiss) in scotland. | two hundred and forty brown trout (salmo trutta) and 49 rainbow trout (oncorhynchus mykiss), obtained from 21 locations in central scotland between october 1990 and august 1993, were examined for endoparasitic helminth infections. crepidostomum farionis (digenea) was the most widely distributed helminth species, followed by eubothrium crassum (cestoda), diphyllobothrium dendriticum and d. ditremum (cestoda), neoechinorhynchus rutili (acanthocephala), echinorhynchus truttae (acanthocephala), eust ... | 1995 | 9599425 |

| observations on the metazoan parasites of the atlantic salmon (salmo salar) after its reintroduction into the elbe river basin in the czech republic. | in the years 1999-2002, first studies were carried out on the metazoan parasites of atlantic salmon (salmo salar l.) recently reintroduced into the elbe river drainage system, after more than 50 years after the complete extinction of the elbe salmon population. a total of six helminth species were recorded from salmon smolts from three streams of the elbe river basin (kamenice river, jestedský and libocanský brooks) in north bohemia, czech republic, where s. salar fingerlings have been released ... | 2003 | 14971599 |
| changes in the neuromodulators of the diffuse endocrine system of the alimentary canal of farmed rainbow trout, oncorhynchus mykiss (walbaum), naturally infected with eubothrium crassum (cestoda). | a histopathological and immunohistochemical study on the intestines of 45 specimens of farmed rainbow trout, oncorhynchus mykiss (walbaum), from loch awe, scotland, revealed a number of cellular deviations in individuals naturally infected with the pseudophyllidean cestode eubothrium crassum (bloch, 1779). twenty-five individuals (55.5%) were infected with an average worm burden of 18.84 +/- 4.06 (mean +/- se) cestodes per host (range, 2-80 worms; total 471 worms). the cestodes, measuring an ave ... | 2005 | 16336471 |
| biomagnification and polychlorinated biphenyl congener distribution in an aquatic predator-prey, host-parasite system. | biomagnification and polychlorinated biphenyl (pcb) congener distribution was examined in a predator-prey, host-parasite system, in which atlantic salmon (salmo salar) preyed upon sprat (sprattus sprattus). eubothrium crassum was an intestinal parasite in salmon that also "preyed upon" sprat, because the parasites gained access to foodstuffs via the host (salmon) gut. salmon contained significantly higher concentrations of total pcbs compared to both parasites and prey (sprat), but no difference ... | 2007 | 17521127 |
| parasitic fauna of the lake brown trout, salmo trutta lacustris (salmonidae), a little known endemic fish from polish waters. | the lake brown trout is a salmonids fish regarded as a stationary form of the migratory trout. within 2003-2004, 31 lake brown trout (salmo trutta lacustris l.) from lake wdzydze (poland), were examined for the presence of parasites following commonly used procedures. the parasites found represented digenea: diplostomum sp., posthodiplostomum cuticola (nordmann, 1832), sphaerostomum globiporum (rudolphi, 1802); cestoda: eubothrium crassum (bloch, 1779), triaenophorus nodulosus (pallas, 1781); ac ... | 2009 | 20209824 |
