One of a group of viruses that have a halo or crown-like (corona) appearance when viewed under a microscope. These viruses are a common cause of mild to moderate upper-respiratory illness in humans and are associated with respiratory, gastrointestinal, liver and neurologic disease in animals.
A virus which can cause diarrhea (scours) and dehydration in young calves. Some "scours vaccines" given to pregnant females will contain coronavirus. Vaccination of the pregnant dam raises the level of antibodies to coronavirus in her colostrum, the first milk she produces which is suckled by the calf after it is born. Antibodies from colostrum provide the calf's immunity for the first few weeks and months of life.
