Explore the latest insights in MAP diagnostics

Animal health storefront

Johne’s disease, or paratuberculosis, is a worldwide animal health problem affecting ruminants. It is caused by infection with Myobacterium avium spp. paratuberculosis (MAP). The presence of the disease can have serious production-limiting consequences and may cause significant economic loss in herds. The disease is difficult to diagnose because of long incubation times.

The identification of subclinical disease in animals, which can shed the organism over long periods and thus be the source of infection for other members of the herd, is crucial for disease control. The combined use of different diagnostic test methods, such as ELISA and real-time PCR tests, helps to identify and remove “shedders” earlier, thus helping to reduce the infection hazard for other healthy animals.




Discover how the right combination of tests can aid in the accurate detection of paratuberculosis.

Featured presenters include Petr Kralik of the Veterinary Research Institute, Czech Republic.

Are you looking to find the best testing solutions to help farmers and veterinarians successfully detect MAP in ruminant herds? In this free on-demand webinar, our presenters share their perspectives on paratuberculosis management, direct and indirect detection options, and insights into how detection solutions can be used to better control the disease in ruminant herds.

Efficient MAP control in goat herds

Dr. Esthel Frederic, consulting veterinarian of GDS18, France, talks about the development of an efficient MAP test protocol for accurate ruminant herd diagnosis. The team at GDS 18 conducted a study in which they compared results of diagnostic testing on individual goats to testing of environmental samples (pooled—bulk milk, milk filter, and swab socks sampled on the same herds).

Detection of MAP shedding in young calves

Dr. Jean-Yves Houtain of ARSIA, Belgium, talks about a recent study using a highly sensitive detection method to assess the risk factors for MAP infections in very young calves. MAP infection in cattle occurs mainly during the first weeks of life. For efficient control of paratuberculosis in an infected herd, it is therefore important to prevent new infections among calves.

Importance of paratuberculosis (Johne’s disease) control

Dr. Petr Kralik of the Veterinary Research Institute, Czech Republic, explains how diagnostic tools can be used to control the disease through the early identification of paratuberculosis levels in animal herds. Paratuberculosis (Johne’s disease) can have a severe impact on the health of cattle and ruminant herds, which can contribute to significant economic losses.
