| 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 ... | 2001 | 11763740 |
| 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), ... | 2005 | 16108550 |
