serologic survey for mycoplasma ovipneumoniae in free-ranging dall sheep (ovis dalli) in alaska.indirect hemagglutination tests on sera from 251 dall sheep (ovis dalli) from interior alaska collected during the period 1979 to 1987 revealed no evidence of exposure to mycoplasma ovipneumoniae. apparently, this potentially fatal disease agent has not been introduced into free-ranging dall sheep populations. in the interest of continued health of such dall sheep, strict enforcement of domestic animal health regulations and prudent land use practices are clearly indicated.19892810563

serologic survey for selected microbial pathogens in alaskan wildlife.antibodies to brucella spp. were detected in sera of seven of 67 (10%) caribou (rangifer tarandus), one of 39 (3%) moose (alces alces), and six of 122 (5%) grizzly bears (ursus arctos). antibodies to leptospira spp. were found in sera of one of 61 (2%) caribou, one of 37 (3%) moose, six of 122 (5%) grizzly bears, and one of 28 (4%) black bears (ursus americanus). antibodies to contagious ecthyma virus were detected in sera of seven of 17 (41%) dall sheep (ovis dalli) and five of 53 (10%) caribou ...19836139490
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
serologic evidence of arbovirus infections in humans and wild animals in alaska.blood samples were collected from humans and several species of free-ranging wild animals in alaska. sera were tested for antibody to jamestown canyon (jc), snowshoe hare (ssh), northway (nor), klamath (kla), sakhalin (sak), great island (gi), and silverwater (sil) virus. jc antibody was found in 54% of 121 human, 89% of 97 bison (bison bison), 51% of 84 dall sheep (ovis dalli), 43% of 68 snowshoe hare (lepus americanus), and 3% of 33 arctic fox (alopex lagopus) sera. ssh antibody was found in 4 ...19836644915
hematologic, serum chemistry and serologic values of dall's sheep (ovis dalli dalli) in june 1979, 73 dall's sheep were captured near tok, alaska to determine selected hematologic and serum metabolite parameters and to determine the presence of antibodies to selected pathogens. hematology and serum metabolite values were compared with values for domestic sheep and bighorn sheep (ovis canadensis). antibodies were detected against brucella sp. (4%), campylobacter feti (30%), contagious ecthyma virus (23%) and bovine parainfluenza type 3 virus (1%). antibodies were not detected aga ...19836887435
contagious ecthyma in an adult dall sheep (ovis dalli dalli) in alaska. 19827097867
contagious ecthyma in alaskan musk-oxen and dall 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
contact transmission of psoroptic mange from bighorn to stone sheep.psoroptes sp. mites and tan crusty lesions were detected in the ears of a captive stone sheep (ovis dalli stonei) in april 1996, after contact with infected captive rocky mountain bighorn sheep (ovis canadensis canadensis). psoroptes spp. have not been detected in free-ranging ungulates in canada or alaska (usa). this is the first report of psoroptes sp. in stone sheep, indicating their susceptibility to infection.19979249721
antibody responses to psoroptes sp. mites in dall sheep (ovis dalli).we determined that antibody responses to psoroptes sp. mites were not present in 403 of 407 sera samples collected opportunistically from 1979 through 1991 from dall sheep (ovis dalli) from five locations in alaska, usa (eastern arctic, n = 61; central arctic, n = 15; western interior, n = 122; central interior, n = 63; eastern interior, n = 146). test values for four samples exceeded the positive cutoff value for the immunoassay, but exposure to mites could not be confirmed since the 95% confid ...19969359078
serologic survey for toxoplasma gondii in selected wildlife species from alaska.blood was collected from selected wildlife species in specific areas of alaska (usa) during 1976-96. a modified agglutination test was used to test sera for evidence of exposure to toxoplasma gondii. serum antibody prevalence was 43% (62 positive of 143 tested) for black bears (ursus americanus), 9% (11/125) for wolves (canis lupus), 7% (22/319) for dall sheep (ovis dalli), 6% (14/241) for caribou (rangifer tarandus), 1% (3/240) for moose (alces alces), and 1% (2/241) for bison (bison bison). a ...200010813602
new host and geographic records for two protostrongylids in dall's sheep.biodiversity survey and inventory have resulted in new information on the distribution of protostrongylidae in dall's sheep (ovis dalli dalli) from the northwest territories (nt, canada) and from alaska (ak, usa). in 1998, parelaphostrongylus odocoilei adults were found for the first time in the skeletal muscles of dall's sheep in the mackenzie mountains (nt). adult p. odocoilei were associated with petechial and ecchymotic hemorrhages and localized myositis; eggs and larvae in the lungs were as ...200111763740
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

population genetic structure of north american thinhorn sheep (ovis dalli).the thinhorn sheep (ovis dalli ssp.) provides a rare example of a north american large mammal that occupies most of its native range and maintains close to ancestral population size. there are currently two recognized subspecies, dall's sheep (o. d. dalli) and stone's sheep (o. d. stonei), the validity of which remains uncertain. we investigated the spatial genetic structure of thinhorn sheep populations representing both subspecies by genotyping individuals (n = 919) from across the species ran ...200415315669
geographic distribution of the muscle-dwelling nematode parelaphostrongylus odocoilei in north america, using molecular identification of first-stage larvae.molecular identification of dorsal-spined larvae (dsl) from fecal samples indicates that the protostrongylid parasite parelaphostrongylus odocoilei occupies a broader geographic range in western north america than has been previously reported. we analyzed 2,124 fecal samples at 29 locations from thinhorn sheep (ovis dalli dalli and o. d. stonei), bighorn sheep (ovis canadensis canadensis and o. c. californiana), mountain goats (oreamnos americanus), woodland caribou (rangifer tarandus caribou), ...200516108550
the serologic prevalence of q fever (coxiella burnetii) complement-fixing antibodies in the peninsular bighorn sheep of southern california.q fever is a rare illness in the southern california desert. during the past 34 years only 6 patients have been diagnosed with the disease at the eisenhower medical center, a referral center for much of the desert and surrounding mountains. in all but 2 instances, q fever was identified in patients who have been in contact with imported domestic sheep who are brought to the desert to graze and lamb in the fall and winter. the sheep are sent back to idaho, wyoming, and montana in the spring. with ...200616896140
