parasite-related lesions in a bearded seal, erignathus barbatus.	a free-ranging adult male bearded seal (erignathus barbatus) killed by polar bears was salvaged and examined at necropsy. significant findings included diffuse intrahepatic bile duct fibrosis and chronic cholangitis; multiple nodules of chronic fibrosing pancreatitis; and gastric ulcers. trematode eggs (family campulidae) were found in the pancreatic nodules. these eggs and the trematodes that produced them probably caused the pancreatic and liver lesions. phocanema decipiens and contracaecum os ...	1979	113564
genetic evidence for three species within pseudoterranova decipiens (nematoda, ascaridida, ascaridoidea) in the north atlantic and norwegian and barents seas.	genetic variation of 1017 specimens of codworm, pseudoterranova decipiens, collected from fish and seals at 23 sampling locations in the north atlantic and norwegian and barents seas, was analysed on the basis of 16 enzyme loci. three reproductively isolated species, provisionally designated p. decipiens a, b and c, were detected, showing distinct alleles at the following loci: mdh-1, 6pgdh, np, pgm, est-2 (between species a and b); mdh-3, 6pgdh, np, sod-1, adk, pgm, est-2, mpi (between a and c) ...	1991	1869354
on the ecology and distribution of pseudoterranova decipiens c (nematoda: anisakidae) in an intermediate host, hippoglossoides platessoides, in northern norwegian waters.	the distribution of pseudoterranova decipiens c helps demonstrate the ecological basis of this genetically defined sibling species. in northern norwegian waters the major fish intermediate host is hippoglossoides platessoides. overall prevalence, mean intensity and intensity range in h. platessoides were 15%, 16.5 and 1-165, respectively. outside the range of its only known definitive host, the seal erignathus barbatus, the parasite was not found in the same intermediate host.	1992	1587684
prevalence of zoonotic anisakid nematodes in inuit-harvested fish and mammals from the eastern canadian arctic.	human anisakidosis is a recognized arctic zoonosis that is directly related to the consumption of traditional inuit foods, particularly raw fish. the epidemiology of infections with the zoonotic anisakid nematodes anisakis simplex and pseudoterranova decipiens was investigated from august 2007 to july 2009 in inuit-harvested fish and marine mammals from inuit regions of nunavik, nunavut, and nunatsiavut, canada. fish were tested for anisakid larvae using the pepsin-hcl digestion method, and the ...	2012	22957974
