The Population History of Domestic Sheep Revealed by Paleogenomes

open access: yesMolecular Biology and Evolution
Abstract Sheep was one of the first domesticated animals in Neolithic West Eurasia. The zooarchaeological record suggests that domestication first took place in Southwest Asia, although much remains unresolved about the precise location(s) and timing(s) of earliest domestication, or the post-domestication history of sheep.

Cross-transmission of resistant gastrointestinal nematodes between wildlife and transhumant sheep

open access: yesPeer Community Journal
Wild and domestic ungulates can be infected with the same species of gastrointestinal parasitic nematodes. These parasites have free-living stages in the environment that contribute to the ease of transmission among different host species.

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]

open access: yesVeterinary Medical Journal - Giza, 2005
The G glycoprotein is the most variable gene among different strains of human and bovine res­piratory syncytial viruses (RSV). One isolate of ovine RSV isolated from domestic sheep has been molecularly characterized before.

Genetic diversity of domestic sheep [PDF]

open access: yes, 2017
Domestic sheep are raised for meat, milk and fibre production and are found all around the world in many types of environments. Sheep have been shown to be genetically diverse but this genetic diversity has not been fully described: there are still many sheep populations which have not yet been studied.
