| 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 |
| climate change and the epidemiology of protostrongylid nematodes in northern ecosystems: parelaphostrongylus odocoilei and protostrongylus stilesi in dall's sheep ( ovis d. dalli ). | we describe the epidemiology of the protostrongylid parasites parelaphostrongylus odocoilei and protostrongylus stilesi in dall's sheep (ovis dalli dalli) from the mackenzie mountains, northwest territories, canada (65 degrees n; 128 degrees w). peak numbers of 1st-stage larvae of both parasites were shed by dall's sheep on their winter range from march until may. in larval development experiments in the mackenzie mountains, peak numbers of infective 3rd-stage larvae of p. odocoilei were availab ... | 2006 | 16332289 |
| protostrongylid parasites and pneumonia in captive and wild thinhorn sheep (ovis dalli). | we describe health significance of protostrongylid parasites (parelaphostrongylus odocoilei and protostrongylus stilesi) and other respiratory pathogens in more than 50 naturally infected dall's sheep (ovis dalli dalli) from the mackenzie mountains, northwest territories (1998-2002) as well as in three stone's sheep (o. d. stonei) experimentally infected with p. odocoilei (2000-2002). histological lesions in the brain and distribution of p. odocoilei in the muscles of experimentally and naturall ... | 2007 | 17495303 |
