New Vaccine Cocktail Protects Cattle from Johne’s Disease

A few months ago, I shared a two-part series on Johne's disease. I talked about the disease itself, and my personal story of losing most of my research goat herd to it back in the early 2000s. It's a devastating disease, and so this news, that scientists are closing in on a vaccine to prevent it, is great news for all of us! Thanks to Jan Suszkiw for this article. Scientists with the Agricultural Research Service's (ARS) National Animal Disease Center’s Infectious Bacterial Diseases Research Unit have developed a new experimental vaccine to protect cattle from the bacterium that causes Johne’s disease, Mycobacterium avium subsp. paratuberculosis (MAP). Johne’s disease, also known as paratuberculosis, is a chronic intestinal disorder that can cause diarrhea, weight loss, poor health and death in afflicted cattle. In the United States, Johne’s disease is most prevalent in dairy herds, costing the industry more than $220 million annually in losses. The disease also affects other ruminant animals, including sheep, goats and deer. Rather than use the cells of live but weakened or dead MAP, as has been done with past commercial vaccine formulations, ARS microbiologists Judy Stabel and John Ba
