  4. Preventive strategy for BVDV infection in North America

    Ridpath, Julia
    Despite 60 years of vaccination, bovine viral diarrhea virus (BVDV) infections remain a source of significant economic loss for producers in the United States. Control program design in the United States varies by region based on the incidence of BVDV, density of animal populations, animal movement, contact with wildlife populations, level of producer compliance, variation among circulating BVDV strains, prevalent type of production unit or industry and support offered by state institutions. The Upper Peninsula BVDV Eradication Program in Michigan, the Montana BVD-PI Herd Biosecurity Project, the Washington State BVDV Testing program and the Alabama Voluntary BVD Control Program illustrates four different regional approaches. All four programs are...

  5. BVDV control and eradication in Europe —an update

    Ståhl, Karl; Alenius, Stefan
    Infections with bovine viral diarrhoea virus (BVDV) are endemic in cattle populations worldwide and result in major economic losses. For long, attempts to control BVDV were limited to prophylactic vaccination practices, implemented primarily to reduce or prevent clinical disease on a herd basis. However, the benefit of preventing clinical disease in transiently infected animals is negligible when considering the overall losses of the disease. Another more systematic strategy to control evolved during the 1990s within eradication programmes in the Scandinavian countries. This was based on an initial determination of herd BVDV status, followed by implementation of systematic zoo-sanitary measures at a regional or national scale (without the use...

  6. Epidemiological situation and control strategies for paratuberculosis in Japan

    Momotani, Eiichi
    Paratuberculosis (Ptb), caused by Mycobacterium avium subsp. paratuberculosis (Map), is a chronic and progressive granulomatous enteritis that affects many livestock and wild animals worldwide. The clinical disease is called Johne’s disease (JD). In Japan, all dairy cattle (harf million head) are examined for Ptb every five years. About 1000 the officially examined cattle are diagnosed annually as positive for Ptb, but most of these exhibit only minor or no clinical signs and typical lesions in recent years. In contrast to the situation in Japan, the disease prevalence in western countries is very high. We have used ELISA and a culture examination of Map, and recently real-time PCR...

  7. Prevalence and Prevention of Paratuberculosis in North America

    Carter, Michael A.
    The United States of America (U.S.) has made several attempts over the years to develop a producer accepted voluntary program. The focus of the U.S. Voluntary Bovine Johne’s Disease Control Program (VBJDCP) is to provide producers with the tools to control Johne’s disease on their farms and identify herds with a low risk for the presence of Mycobacterium avium subspecies paratuberculosis (MAP) infection. The VBJDCP includes an evaluation of producers’ operations to identify practices that could allow the transmission of MAP among animals or between premises. Once risky practices have been identified, a herd management plan is developed to assist the producer in correcting risky practices. In addition...

  8. Examples and Suggestions for the Control of Paratuberculosis in European Cattle

    Khol, Johannes Lorenz; Baunmgartner, Walter
    Paratuberculosis, or Johne’s disease (JD), is caused by Mycobacterium avium subspecies paratuberculosis (MAP), is found in ruminants worldwide and can cause considerable economic losses in cattle. Control efforts and programs for JD in cattle are very diverse among European states, in Austria clinical JD is rated as a notifiable disease since 2006. The voluntary control programs established in many European countries, show different aims, measurements and acceptance. Most control programs for JD are based on a test and cull strategy, combined with hygienic precautions. Unfortunately, the willingness to participate in such programs by farmers and veterinarians is limited due to high costs, intensive workload, long duration and limited success. To...
