About the Abstract: Bovine Coronavirus
Dr. Brad White and Dr. Todd Gunderson discuss a study on bovine coronavirus and its role in respiratory disease in cattle. The study, published in Frontiers in Veterinary Science, used a challenge model with 15 challenge calves and six control calves. Results showed higher viral shedding in challenge calves. PCR detected bovine coronavirus in multiple tissues but not in the lungs or tracheobronchial lymph nodes. Histopathology scores indicated more pathology in challenge calves, but clinical signs were mild. The study suggests bovine coronavirus may play a role in mild respiratory disease but not in severe pneumonia, possibly acting as a co-factor for secondary infections.
