hematologic, serum chemistry and serologic values of dall's sheep (ovis dalli dalli) in alaska.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
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
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
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
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
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
