anti-brucella antibodies in moose (alces alces gigas), muskoxen (ovibos moschatus), and plains bison (bison bison bison) in alaska, usa.we used an indirect enzyme-linked immunosorbent assay (ielisa) and the rose bengal test (rbt) to test for anti-brucella antibodies in moose (alces alces gigas), muskoxen (ovibos moschatus), and plains bison (bison bison bison) from various game management units (gmus) in alaska, us, sampled from 1982 to 2010. a portion of the sera had previously been tested with the standard plate test (spt), the buffered brucella antigen (bba) card test, and the card test (card). no antibody-positive plains bis ...201626540335
disease complexity in a declining alaskan muskox (ovibos moschatus) population.the muskox ( ovibos moschatus ) population inhabiting the eastern north slope (ens) of alaska, us declined dramatically during 1999-2006, whereas populations in western alaska (wa) were stable or increasing. to understand morbidity and mortality factors contributing to the decline, alaska department of fish and game conducted pathologic investigations of carcasses from 2005 until 2008. additionally, archived sera from both ens and wa muskoxen collected during 1984-92, before the documented begin ...201728099077
serum antibody prevalence of malignant catarrhal fever viruses in seven wildlife species from alaska.blood samples were collected from seven species of free-ranging ungulates in alaska. sera were tested for evidence of exposure to malignant catarrhal fever viruses (mcfv) by means of a competitive enzyme-linked immunosorbent assay. antibody prevalences were as follows: muskox (ovibos moschatus) 100 positive samples of 104 tested (96%); dall sheep (ovis dalli) 212 of 222 (95%); elk (cervus elaphus) 14 of 51 (27%); bison (bison bison) 34 of 197 (17%); caribou (rangifer tarandus) nine of 232 (4%); ...200212238366
contagious ecthyma in alaskan musk-oxen and dall sheep.in 1976 and 1977, a disease resembling contagious ecthyma was seen in captive musk-oxen (ovibos moschatus) in alaska. a similar disease occurred in 1977 in captive dall sheep (ovis dalli). paravaccinia viruses were detected by electron microscopy and isolated in cell cultures from both species. experimental inoculation in susceptible and immune domestic sheep (ovis aries) plus fluorescent antibody tests with ecthyma-immune conjugate indicated that the isolate was contagious ecthyma virus.19817327995
serologic and experimental investigations of contagious ecthyma in alaska.serologic evidence of contagious ecthyma (ce) was found in domestic sheep (ovis aries), domestic goats (capra hircus), dall sheep (ovis dalli), and musk-ox (ovibos moschatus) in alaska. a moose (alces alces) calf and a caribou (rangifer tarandus) fawn were susceptible to experimental infection and both developed antibody titers as a result. ce virus was isolated from lesions of dall sheep which were involved in a natural outbreak of the disease.19836644914
possible secondary population-level effects of selective harvest of adult male muskoxen.selective harvest regimes are often focused on males resulting in skewed sex-ratios, and for many ungulate species this strategy is sustainable. however, muskoxen (ovibos moschatus) are very social and mature bulls (≥4 years old), particularly prime-age bulls (6-10 years old), play important roles in predator defense and recruitment. a year-round social structure incorporating large males into mixed-sex groups could make this species more susceptible to the effects of selective harvest if popula ...201323818982
