serosurvey for toxoplasma gondii in arctic foxes and possible sources of infection in the high arctic of svalbard.samples (blood or tissue fluid) from 594 arctic foxes (alopex lagopus), 390 svalbard reindeer (rangifer tarandus platyrhynchus), 361 sibling voles (microtus rossiaemeridionalis), 17 walruses (odobenus rosmarus), 149 barnacle geese (branta leucopsis), 58 kittiwakes (rissa tridactyla), and 27 glaucous gulls (larus hyperboreus) from svalbard and nearby waters were assayed for antibodies against toxoplasma gondii using a direct agglutination test. the proportion of seropositive animals was 43% in ar ...200717950534
enterobacter cloacae with a novel variant of act ampc beta-lactamase originating from glaucous gull (larus hyperboreus) in svalbard.we aimed at escherichia coli and enterobacter cloacae isolates resistant to cephalosporins and fluoroquinolones and salmonella isolates in wild birds in arctic svalbard, norway. cloacal swabs of little auks (alle alle, n=215) and samples of faeces of glaucous gulls (larus hyperboreus, n=15) were examined. inducible production of ampc enzyme was detected in e. cloacae kw218 isolate. sequence analysis of the 1146 bp pcr product of the ampc gene from this isolate revealed 99% sequence homology with ...201424629772
persistent organic pollutants, heavy metals and parasites in the glaucous gull (larus hyperboreus) on spitsbergen.the prediction of a higher parasite infection as a consequence of an impaired immune system with increasing persistent organic pollution (pop) and heavy metal levels were investigated in adult glaucous gull (larus hyperboreus) from svalbard. the levels of chlorinated pesticides, polychlorinated biphenyls (pcbs), toxaphenes and polybrominated diphenyl ethers (pbdes) were measured in liver. copper, cadmium, lead, mercury, selenium and zinc were measured in kidney samples. an elevated ratio of pcb- ...201319364623
organochlorines in top predators at svalbard--occurrence, levels and effects.alarmingly high polychlorinated biphenyl (pcb) levels have been found in the top predators such as glaucous gull (larus hyperboreus) and polar bear (ursus maritimus) at svalbard [gabrielsen, g.w., skaare, j.u., polder, a., bakken, v., 1995. chlorinated hydrocarbons in glaucous gull (larus hyperboreus). sci. total environ. 160/161, 337-346; bernhoft, a., skaare, j.u., wiig, o., 1997. organochlorines in polar bears (ursus maritimus) at svalbard. environ. pollut. 95, 159-175; henriksen, e.o., gabri ...200010720718
