Gene Based Test For Johne’s Disease
If you aren’t familiar with Johne’s disease–the most costly disease facing the dairy cattle industry right now–you aren’t alone.
Johne’s (pronounced YO-nees) disease, which costs the U.S. dairy industry more than $1.5 billion annually, is caused by a bacterium that infects ruminant animals. Mycobacterium paratuberculosis is related to, but different from, the organism that causes cattle tuberculosis.
USDA’s National Animal Health Monitoring Survey (NAHMS) Dairy 1996 Study reports that 45 percent of dairy producers were either unaware of Johne’s disease or recognized the name but knew little about it.
