Penn State gets Johne’s disease grant


UNIVERSITY PARK, Pa. — Penn State’s College of Agricultural Sciences has been awarded a four-year, $4.8 million grant from the U.S. Department of Agriculture’s Cooperative State Research, Education and Extension Service to support phase two of a major international effort aimed at promoting animal biosecurity and mitigating losses from Johne’s disease in livestock.


The Johne’s Disease Integrated Program — a consortium of 170 scientists from more than 50 academic institutions, government agencies and industry organizations around the world — is led by Vivek Kapur, head of Penn State’s Department of Veterinary and Biomedical Sciences.

The program’s research emphases include epidemiology and transmission of Johne’s disease; the development of diagnostic tests; understanding the biology of the pathogen and how it causes the disease; and studying how the body responds to the pathogen, with an eye toward vaccine development.

In addition, the program has a large outreach component designed to train veterinarians and producers so they can better manage, control and prevent the disease.

Johne’s disease

Johne’s disease is a chronic, bacterial intestinal disease of cattle and other ruminants (sheep, deer, goats) that can cause weight loss, diarrhea and decreased milk production.

National estimates indicate up to 70 percent of dairy herds and a smaller percentage of beef herds have cattle with Johne’s disease.

Annual economic losses to producers as a result of Johne’s disease are estimated at more than $14 million in Pennsylvania, up to $500 million in the U.S. and as much as $1.5 billion worldwide.


An objective of Johne’s Disease Integrated Program is to help reduce these losses by shortening the time between discovery research and its field application.

Kapur notes the grant will enable the Johne’s consortium to build on the accomplishments from the first three-year phase of the project.

“Our collaborative work has led to improvements in diagnostic tests, a better understanding of mechanisms of disease transmission and pathogenesis, and the identification of new vaccine candidates,” he said.

“Our consortium also has enabled the development of online training programs on Johne’s disease for veterinarians and producers.”

Improved sampling and testing strategies developed by Johne’s Disease Integrated Program are currently being incorporated into USDA’s Voluntary Bovine Johne’s Disease Control Program.

Information generated by Johne’s Disease Integrated Program also has enhanced many state Johne’s certification programs.

The Pennsylvania Johne’s Disease Herd Certification Program, sponsored by the state Department of Agriculture in cooperation with Penn State’s College of Agricultural Sciences, is one of the nation’s longest-running voluntary Johne’s disease monitoring and control programs.
