Thank you Nanno! Great study refuting contact transmission between domestic goats and bighorn sheep.
So, per this study: Foreyt WJ. Effects of controlled contact exposure between healthy bighorn sheep and llamas, domestic goats, mountain goats, cattle, domestic sheep, or mouflon sheep. Proceedings of the Biennial Symposium of the Nothern Wild Sheep and Goat Council 1994;9:7–14.
"Bighorn sheep remained clinically healthy during and after contact with llamas, cattle, mountain goats, and domestic goats, but all bighorn sheep died from acute bronchopneumonia after contact with domestic sheep.."
