Information on health parameters, such as antibody prevalences and serum chemistry that can reveal exposure to pathogens, disease, abnormal physiologic conditions, is scarce for Antarctic seal species. Serum samples from fur seals (Arctocephalus gazella, n=88) Bouvetøya (2000–2001 2001–2002), Weddell (Leptonychotes weddellii, n=20), Ross (Ommatophoca rossii, crabeater (Lobodon carcinophagus, n=9) the pack-ice off Queen Maud Land, Antarctica (2001) were analyzed enzyme activity,...
Hypoderma tarandi causes myiasis in reindeer and caribou (Rangifer tarandus spp.) most northern hemisphere regions where these animals live. We report a series of 39 human cases caused by H. Norway from 2011 to 2016. Thirty-two were residents Finnmark, the northernmost county Norway, one visitor six lived other counties Clinical manifestations involved migratory dermal swellings face head, enlargement regional lymph nodes, periorbital oedema, with or without eosinophilia. Most are seen...
Serum samples from 419 polar bears (Ursus maritimus) Svalbard and the Barents Sea (collected 1990-2000) 108 East Greenland 1999-2004) were assayed for antibodies against Toxoplasma gondii using modified agglutination test. Antibody prevalences 3.6% among cubs dependent on their mothers 21.4% subadults adults. Among adults there was an interaction between population sex, with similar females (Svalbard = 19.5%, 18.0%), but a high frequency males (28.7%) as compared to (5.8%). The pattern also...
A species-independent indirect enzyme-linked immunosorbent assay (iELISA) based on chimeric protein A/G was established for the detection of anti- Brucella antibodies in Arctic wildlife species and compared to previously brucellosis serological tests hooded seals ( Cystophora cristata), minke whales Balaenoptera acutorostrata), sei borealis), fin physalus), polar bears Ursus maritimus), as well bacteriology results reindeer caribou Rangifer tarandus sp.). The iELISA were consistent with...
Arctic foxes, 620 that were trapped and 22 found dead on Svalbard, Norway (1996–2004), as well 10 foxes in Nenets, North-West Russia (1999), tested for rabies virus antigen brain tissue by standard direct fluorescent antibody test. Rabies was two from Svalbard three Russia. Blood samples 515 of the fox carcasses screened antibodies with negative result. Our results, together a previous screening (1980–1989, n=817) indicate prevalence has remained low or not been enzootic arctic population...
We assayed blood/tissue fluid samples from 20 harbour porpoises Phocoena phocoena western Greenland coastal waters for antibodies against the protozoan parasite Toxoplasma gondii by direct agglutination test (DAT). Nine individuals (45%) were interpreted to be seropositive at 1:40 dilution and 4 (20%) up 1:160. Samples these an enzyme-linked immunosorbent assay (ELISA), tissue of DAT-positive animals tested a nested polymerase chain reaction (nPCR). Results both methods negative, suggesting...
The psoriasis‐associated antigen, pso p27, and antibodies recognizing this antigen were demonstrated in extracts from psoriatic scales. It was that the present complexes containing IgG as well complement factor Clq. studied with respect to complement‐activating potential. This measured ability of induce generation C5a using rabbit serum source complement. data obtained showed p27‐containing able activate system, indicating p27 may contribute inflammatory process psoriasis.
Cultured epidermal malpighian cells and experimental wounds of Atlantic salmon Salmo salar were challenged with a variety particulate materials. Latex beads the bacteria Carnobacterium piscicola, Pseudomonas fluorescens Aeromonas salmonicida engulfed by cultured cells, whereas Staphylococcus intermedius not. The that proliferated in culture medium devoid antibiotics melanin granules other cellular debris. Cells at wound margins latex C. P. A. s. , but not S. intermedius. Malpighian thus...
Summary The coccidian protozoan Toxoplasma gondii has a world-wide distribution. It causes toxoplasmosis, potentially very serious disease to humans and other warm-blooded animals. Infection in many studies been shown be rather common the Nordic countries also, where its prevalence both domestic animals wildlife can explained by contacts with cats their faeces, wild felids being only definitive hosts of parasite known. Before discovery complete life cycle parasite, infection routes were...
An assay method for the determination of ivermectin in reindeer feces was developed. Ivermectin quantified by high-performance liquid chromatography and fluorescence detection after extraction (acetone, isooctane), cleanup (C-18 solid-phase column), derivatization to a fluorescent derivative using N-methylimidazole trifluoroacetic anhydride. Concentration calculations were based on calibration lines found from analyses standards prepared feces. Abamectin used as internal standard. determined...
Have Although persistent organic pollutants (POPs) may affect the immune system, few field studies actually examined this effect. There are indications that POP exert effects on system; however, in Arctic ecosystem data scarce. The aim of study was to examine functions two medium trophic-positioned seabirds, black-legged kittiwakes (Rissa tridactyla) and Atlantic puffins (Fratercula arctica). Overall concentrations were higher than males had significantly females. Mean total polychlorinated...
