A recently-completed research project funded by the National Check-off and Canada’s Beef Science Cluster studied polymerase chain reaction (PCR) tests, which detect specific DNA sequences, as a potentially cost-effective and practical diagnostic testing strategy for identifying beef cattle with vibrio.
