Novel CRISPR/Cas13-based assay for detection of bovine coronavirus associated with severe diarrhea in calves.

Bovine coronavirus (BCoV) is one of the important causes of diarrhoea in cattle. The virus is responsible for the high fatality rate associated with acute diarrhoea in calves. Rapid and accurate tests need to be conducted to detect the virus and minimise economic losses associated with the disease.
