Several of South Dakota’s newest herd of big horn sheep have tested positive for bacteria which cause pneumonia, reports the Black Hills Pioneer. Currently, experts are trying to determine where the sheep contracted the disease. The herd was scheduled for augmentation, which has now been placed on hold until the animals are found to be free of the deadly bacteria.
Contact with a domestic animal outside of the herd would have been necessary to contract the disease. Wildlife officials are aware of contact with a sheep from outside the herd, but the animal later tested negative for the pathogen in question.
