Blackleg, also known as clostridial myositis, is a serious, often fatal disease that primarily affects cattle. It's caused by a spore-forming bacterium that is commonly found in soil and the gastrointestinal tracts of healthy animals and has deadly impacts, if not caught in time. In this episode, Dr. Brandon Dominguez and Dr. Alexis Thompson visit with Dr. Tegner Jacobson, microbiology section head in Canyon, to discuss the disease and testing options that may be of interest to producers.
