Poor health, viruses, and environmental stress can leave young calves susceptible to secondary bacterial infections that cause bovine respiratory disease (BRD). These severe infections commonly result in pneumonia, and treatments can be costly.
To identify unique proteins that can be used for future interventions against this disease in cattle, scientists at the United States Department of Agriculture (USDA), Agricultural Research Service (ARS), took a closer look at the genetic material of multiple subtypes (strains) of three groups of bacterial species commonly implicated with BRD.
