HELMINTH PARASITES OF BIGHORN SHEEP IN OREGON [PDF]
The lungs and gastrointestinal tracts from 18 hunter-killed bighorn rams (Ovis canadensis californiana) were examined in total or in part for helminth parasites during a two-year study of three separate herds in Eastern Oregon. Prevalence was 100% with the lungworm Protostrongylus stilesi.

PARTIAL NUCLEOTIDE SEQUENCE OF THE G GLYCOPROTEIN OF RESPIRATORY SYNCYTIAL VIRUS ISOLATED FROM WILD BIGHORN SHEEP MAY PROVE THAT IT IS NEARLY IDENTICAL TO THAT OF OVINE RESPIRATORY SYNCYTIAL VIRUS OF DOMESTIC SHEEP [PDF]
The G glycoprotein is the most variable gene among different strains of human and bovine resÂpiratory syncytial viruses (RSV). One isolate of ovine RSV isolated from domestic sheep has been molecularly characterized before.

Hemorrhagic Disease in Bighorn Sheep in Arizona [PDF]
Two bighorn sheep from Arizona (USA) were submitted for necropsy. One was a Rocky Mountain bighorn (Ovis canadensis canadensis) and the other was a desert bighorn (Ovis canadensis mexicana). Both had lesions consistent with those of hemorrhagic disease (HD).

Experimental Transmission of Bighorn Sheep Sinus Tumors to Bighorn Sheep ( Ovis canadensis canadensis ) and Domestic Sheep [PDF]
Bighorn sheep sinus tumors are a recently described disease affecting the paranasal sinuses of Rocky Mountain bighorn sheep ( Ovis canadensis canadensis). Several features of this disease suggest an infectious cause, although a specific etiologic agent has not been identified.

An individual-based modelling approach to estimate landscape connectivity for bighorn sheep (Ovis canadensis) [PDF]
Background. Preserving connectivity, or the ability of a landscape to support species movement, is among the most commonly recommended strategies to reduce the negative effects of climate change and human land use development on species.

Bighorn Sheep and Mountain Goats
Abstract Bighorn sheep (Ovis canadensis), and to a lesser extent mountain goats (Oreamanos americanus), historically occupied much of the mountainous rangelands of western North America. Both ungulates inhabit rugged terrain and feed on grasses, forbs, and browse.

Transmission of infectious agents from livestock reservoirs has been hypothesized to cause respiratory disease outbreaks in bighorn sheep (Ovis canadensis), and land management policies intended to limit this transmission have proven controversial.

Behaviorâspecific habitat models as a tool to inform ungulate restoration
Across North America, many ungulate species that experienced historic population declines and range contractions are now broadly distributed across their native ranges after the implementation of successful restoration programs.

Assessing respiratory pathogen communities in bighorn sheep populations: Sampling realities, challenges, and improvements. [PDF]
Respiratory disease has been a persistent problem for the recovery of bighorn sheep (Ovis canadensis), but has uncertain etiology. The disease has been attributed to several bacterial pathogens including Mycoplasma ovipneumoniae and Pasteurellaceae ...
