antibodies to brucella in marine mammals around the coast of england and wales.following the isolation of previously unrecognised species of brucella from stranded seals and cetaceans in scotland and northern england, a serological survey was carried out to investigate the range of marine mammal species which may have been exposed to brucella species around the coasts of england and wales, the prevalence of infection and the temporal and geographical distribution of seropositive animals. serum collected from 153 stranded marine mammals from the coasts of england and wales ...19979416675
a significant downturn in levels of hexabromocyclododecane in the blubber of harbor porpoises (phocoena phocoena) stranded or bycaught in the uk: an update to an earlier paper, we reported data indicating a sharp increase in hexabromocyclododecane concentrations in the blubber of 85 harbor porpoises from the uk, from about 2001 onward. that time trend was evaluated using data from 1994-2003, generated on a diastereoisomer basis using lc-ms. in this paper we report additional data for 138 animals collected during 2003-2006. sigmahbcd concentrations ranged from <10 to 11,500 microg kg(-1) wet weight (up to 12,800 microg kg(-1) lipid weight) and tbbp- ...200819174878
prevalence of a host-adapted group b salmonella enterica in harbour porpoises (phocoena phocoena) from the south-west coast of england.a monophasic group b salmonella enterica 4,12:a:- was first isolated in harbour porpoises (phocoena phocoena) in scotland in 1991. this paper reports the isolation of the same group b s enterica from harbour porpoise carcases found stranded along the cornwall and devon coastlines. between 1991 and 2002, 80 harbour porpoises were submitted for postmortem examination and subjected to bacteriological examination under the uk cetacean strandings investigation programme. a total of 28 salmonella isol ...201020675627
exposure to heavy metals and infectious disease mortality in harbour porpoises from england and wales.we investigate whether long-term exposure to heavy metals, including immunosuppressive metals like mercury (hg), is associated with infectious disease in a wild cetacean. post-mortem investigations on 86 harbour porpoises, phocoena phocoena, found dead along the coasts of england and wales revealed that 49 of the porpoises were healthy when they died as a consequence of physical trauma (most frequently entrapment in fishing gear). in contrast, 37 porpoises died of infectious diseases caused by p ...200111202652
occurrence of a monophasic strain of salmonella group b isolated from cetaceans in england and wales between 1990 and 2002.between september 1990 and december 2002, 511 cetacean carcasses stranded or caught in commercial fisheries in england and wales were examined post mortem. salmonella group b was isolated from 60 of 279 (21.51%) harbour porpoises (phocoena phocoena), predominantly from lung tissue. forty-three of the salmonella group b isolates were subsequently serotyped and all found to have the antigenic structure o4,12:a:-. the annual proportion of harbour porpoises testing positive for salmonella o4,12:a:- ...200818492065
marine mammals from northeast atlantic: relationship between their trophic status as determined by delta13c and delta15n measurements and their trace metal concentrations.the relationship between trophic position through delta13c and delta15n and trace metal concentrations (zn, cd, cu and hg) was investigated in the tissues of six marine mammal species from the northeast atlantic: striped dolphin stenella coeruleoalba, common dolphin, delphinus delphis, atlantic white-sided dolphin lagenorhynchus acutus, harbour porpoise phocoena phocoena, white beaked-dolphin lagenorhynchus albirostris, grey seal halichoerus grypus stranded on french channel and irish coasts. wh ...200312738219
morbillivirus infection in two common porpoises (phocoena phocoena) from the coasts of england and scotland.two common porpoises (phocoena phocoena), one found stranded on the isle of sheppey, kent, and the other in the moray firth, scotland, in late 1990, were examined post mortem. lesions of diffuse bronchointerstitial pneumonia were present in both animals; they were characterised by the infiltration of alveoli with leucocytes, macrophages and multinucleate syncytia, the necrosis of bronchial and bronchiolar epithelium, focal proliferation of type ii pneumocytes and occasional acidophilic cytoplasm ...19921441126
investigating potential associations between chronic exposure to polychlorinated biphenyls and infectious disease mortality in harbour porpoises from england and wales.bioaccumulation of immunosuppressive organochlorines like polychlorinated biphenyls (pcbs) may pose a threat to the health and viability of cetacean populations. to investigate possible associations between chronic exposure to pcbs and infectious disease mortality in harbour porpoises phocoena phocoena in uk waters, blubber concentrations of 25 individual chlorobiphenyl (cb) congeners in 34 healthy harbour porpoises that died due to physical trauma (mainly by-catch) were compared with cb concent ...199910635603
entanglement in fishing gear and other causes of death in cetaceans stranded on the coasts of england and wales.between august 1990 and september 1995 the carcases of 422 cetaceans of 12 species that had died around the coasts of england and wales were examined. there were 234 harbour porpoises (phocoena phocoena), 138 common dolphins (delphinus delphis), and 50 individuals of 10 other species of dolphins and whales. the cause of death was diagnosed in the harbour porpoises and common dolphins was entanglement in fishing gear (bycatch). of the cases in which the cause of death was established, 66 (38 per ...19979265709
postmortem evidence of interactions of bottlenose dolphins (tursiops truncatus) with other dolphin species in south-west england.reports of violent interactions between bottlenose dolphins (tursiops truncatus) and harbour porpoises (phocoena phocoena) in the coastal waters of the uk are well documented. examination of stranded cetaceans by the cornwall wildlife trust marine strandings network and the uk cetacean strandings investigation programme has indicated that seven animals, of four other species, found stranded in south-west england, had pathology consistent with bottlenose dolphin interaction, including two juvenil ...200919820259
