Bovine Paratuberculosis (Johne's Disease) Information Sources

Version 2.3     Updated April 05, 2010

Purpose:

The purpose is to provide links to on-line bovine paratuberculosis materials for students, for livestock producers and for their veterinarians. Please let me know if you find materials I've overlooked or if I've made an error. This webpage does not  provide herd-specific advice and likely does not reflect the current veterinary literature or on-line materials. I have not verified the accuracy and usefulness of these items below so you must use your own judgment. If you are not qualified to do so, please discuss them with someone who is. If you are a producer, this should include being familiar with your operation and the infection situation in your herd. Inclusion does not imply endorsement nor does omission imply disapproval.

Johne's Disease - Information for Veterinarians

The American Association of Bovine Practitioners' Food Safety Committee collaborated with the National Johnes Working Group, a subcommittee of the Johne's Committee of the USAHA, linked below, to produce a series of information guides on Johne's Disease for the bovine practitioner and their clients.

Mycobacterium avium paratuberculosis: Infrequent human pathogen or public health threat? (C Nacy, M Buckley, 2008) 41 pg pdf

Cornell Consultant (Dr. M. E. White, Cornell - references and links to other on-line materials))

For the major species and their diseases, Dr. White's site links clinical signs to the diseases with their clinical signs, a brief disease description and a list of relevant recent clinical literature with links to on-line materials.

PubMed - National Library of Medicine

As the National Library of Medicine indexes almost all of the scientific human medical literature and a large portion of the scientific veterinary literature and abstracts are provided for most papers that it indexes, it is an excellent resource for identifying recent publications on medical and veterinary topics and for obtaining some information from the abstracts. It also has a "Related Articles" function that you can use to identify similar papers to those that you find useful. The following are some direct searches.

The Merck Veterinary Manual

United Kingdom Food Standards Agency

United States Animal Health Association

USAHA is a national, public non-profit organization comprised of scientists, veterinarians, industry representatives, producer organization representatives and government officials that meets annually to recommend public policy and research agendas with regard to animal health issues. Within the organization are committees that each focus on a major disease or issue.

Crohn's Disease and its association with Bovine Paratuberculosis (Johne's Disease):

That a portion of Crohn's disease cases are associated with Mycobacterium paratuberculosis is well established in the scientific literature, which is one reason for the human public health community's heightened concern about bovine paratuberculosis. What isn't definitively established but is an area of active research is whether or not the organism causes these Crohn's disease cases. Some of the following papers and sites deal with this issue.

Agri-Food Risk Management & Communication

Dr. Powell's interest is the consumer's perception of risk, what they expect an industry to be doing about a risk associated with a product, their reaction to adverse publicity about a product and how an industry can prepare itself for and respond to such events.
