Investigations of hooded seals Cystophora cristata have revealed high prevalences Brucella-positive in the reduced Northeast Atlantic stock, compared to increasing Northwest stock. This study evaluated relation between Brucella-serostatus stock and age, sex, body condition reproduction. Bacteriology documented which animals organs were B. pinnipedialis positive. No relationship was observed or reproductive traits. Pups (<1 mo old) had a substantially lower probability being seropositive...
Abstract Background The reindeer brainworm, Elaphostrongylus rangiferi , is a protostrongylid parasite of that has caused severe disease outbreaks in husbandry. E. considered ubiquitous Norway, though most published prevalence studies are from Finnmark county only. In the present study, faecal samples were collected over three winter seasons (2013–2016) eight herds semi-domesticated Eurasian tundra ( Rangifer tarandus ) distributed all herding area Norway. Baermann’s technique was used to...
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,...
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...
The environmental temperature has profound effects on biological systems of marine aquatic organisms and plays a critical role in species distribution abundance. Particularly during the warmer seasons, variations habitat may introduce episodes stressful temperatures which must adapt to compensate for maintain physiological homeostasis. environment is changing predicted raises water will affect numerous species. Translocation pathogens follow migration alternations physical parameters have...
Boreal woodland caribou (Rangifer tarandus caribou) are listed as threatened across Canada, and a basic understanding of their health status is lacking. From December 2012 to April 2013, we investigated multiple indices for adult female boreal (n=163) captured from seven herds in NE British Columbia, Canada. Health included physical characteristics, physiologic trace mineral status, exposure or infection with selected pathogens, measures chronic stress inflammation, including serum amyloid...
Supplementary winter feeding of semi-domesticated reindeer (Rangifer tarandus tarandus) has become more common in Sweden and Norway due to pasture fragmentation climatic conditions. With increased corralling feeding, often associated with animal stress, animal-to-animal contact, poor hygienic conditions, an altered range health challenges diseases may emerge. An outbreak three different infectious appeared simultaneously a herd Norrbotten County, Sweden. The animals were corralled fed...
Brucella serostatus was evaluated in 3189 muskoxen sampled between 1989 and 2016 from various locations of the Canadian Arctic archipelago mainland, near communities Sachs Harbour Ulukhaktok, Northwest Territories, Cambridge Bay Kugluktuk, Nunavut. antibodies were found only around Bay, both on southern Victoria Island adjacent mainland (Kent Peninsula). Consistent with participatory epidemiology data documented local harvesters describing increased Brucella-like syndromes (swollen joints...
Pathology has not been observed in true seals infected with Brucella pinnipedialis. A lack of intracellular survival and multiplication B. pinnipedialis hooded seal (Cystophora cristata) macrophages vitro indicates a chronic infection seals. Both epidemiology bacteriological patterns the point to transient environmental origin, possibly through food chain. To analyse potential role fish transmission pinnipedialis, Atlantic cod (Gadus morhua) were injected intraperitoneally 7.5 x 107 bacteria...
Brucella pinnipedialis was first isolated from true seals in 1994 and eared 2008. Although few pathological findings have been associated with infection seals, reproductive pathology including abortions, the isolation of zoonotic strain type 27 documented seals. In this study, a enzyme-linked immunosorbent assay (ELISA) Rose Bengal test (RBT) were initially compared for 206 serum samples discrepancy between tests found. Following removal lipids samples, ELISA results unaltered while...
Marine mammal Brucella spp. have been isolated from pinnipeds (B. pinnipedialis) and cetaceans ceti) around the world. Although zoonotic potential of marine brucellae is largely unknown, reports human disease exist. There are few studies mechanisms bacterial intracellular invasion multiplication involving We examined infective capacity two genetically different B. pinnipedialis strains (reference strain; NTCT 12890 a hooded seal isolate; B17) by measuring ability bacteria to enter replicate...
Infectious keratoconjunctivitis (IKC) is a transmissible disease in semi-domesticated Eurasian reindeer (Rangifer tarandus tarandus). It regarded as multifactorial and single causative pathogen has not yet been identified. From clinical outbreaks we have previously identified Cervid herpesvirus 2 (CvHV2) Moraxella bovoculi candidates for experimental investigations. Eighteen were inoculated the right eye with CvHV2 (n = 5), M. 5) or sterile saline water 3; controls).All animals CvHv2, alone...
Infectious keratoconjunctivitis (IKC) is one of the most common ocular diseases in ruminants worldwide. In addition to keratitis and conjunctivitis, animals with IKC can develop uveitis, corneal ulcer, severe cases, blindness. The bacteria Moraxella spp. has been described as primary causative agent infectious bovine (IBK) cattle (Bos taurus), while Chlamydia Mycoplasma conjunctivae are considered main agents sheep (Ovis aries). Previous studies indicated cervid herpesvirus 2 (CvHV2)...
Pathogens can impact host survival, fecundity, and population dynamics even when no obvious disease is observed. Few baseline data on pathogen prevalence diversity of caribou are available, which hampers our ability to track changes over time evaluate impacts health. Archived blood samples collected from ten migratory herds in Canada two Greenland were used test for exposure pathogens that have the potential effect productivity, zoonotic or emerging. Relationships between seroprevalence...
Natural cases of zooanthroponotic transmission SARS-CoV-2 to animals have been reported during the COVID-19 pandemic, including free-ranging white-tailed deer (Odocoileus virginianus) in North America and farmed American mink (Neovison vison) on multiple continents. To understand potential for angiotensin-converting enzyme 2 (ACE2)-mediated viral tropism we characterised distribution ACE2 receptors respiratory intestinal tissues a selection wild semi-domesticated mammals artiodactyls...
Brucella species infecting marine mammals was first reported in 1994 and the years since has been documented various of pinnipeds cetaceans. While these reports have included that inhabit Arctic waters, few available studies on bearded seals Erignathus barbatus failed to detect infection date. We report isolation pinnipedialis from a seal. The isolate recovered mesenteric lymph node seal stranded Scotland typed as ST24, sequence type associated typically with pinnipeds. Furthermore,...
A high prevalence of Brucella pinnipedialis serology and bacteriology positive animals has been found in the Northeast Atlantic stock hooded seal (Cystophora cristata); however no associated gross pathological changes have identified. Marine mammal brucellae previously displayed different infection patterns human murine macrophages. To investigate if marine spp. are able to invade multiply cells originating from a presumed host species, we infected alveolar macrophages with B. isolate....
The reindeer (Rangifer tarandus tarandus) industry in Alaska began with animals imported from Siberia (Russia) the 1890's. Cervid herpes virus 2 (CvHV2) is endemic Scandinavia. We sought to determine if same virus, or similar herpesviruses, were circulating Alaskan and caribou granti). Serum samples 292 collected during annual handlings (1988-2005) near Nome, Alaska. In 2005, swab 40 calves this herd, 2007, ocular nasal 30 apparently healthy Wales, Samples of plasma white blood cells three...
Marine Brucella spp. have been isolated from numerous pinniped and cetacean species, but pathological findings in association with infection pinnipedialis pinnipeds sparse. The capacity of brucellae to survive replicate within host macrophages underlies their important ability produce chronic infections, previous work has shown that B. are rapidly eliminated hooded seal (Cystophora cristata) alveolar macrophages.To investigate if multiplication could take place other cell types, primary...
