Animal Health in Minnesota Annual Report of the Minnesota Veterinary Diagnostic Laboratory Fiscal Year 1999 (July 1, 1998- June 30, 1999) in cooperation with Department of Veterinary Diagnostic Medicine College of Veterinary Medicine University of Minnesota and Minnesota Board of Animal Health Miscellaneous Publication 101-1999 Minnesota Agricultural Experiment Station University of Minnesota St. Paul, Minnesota The University of Minnesota, including the Minnesota Agricultural Experiment Station, is committed to the policy that all persons shall have equal access to its programs, facilities, and employment without regard to race, color, creed, religion, national origin, sex, marital status, disability, public assistance status, veteran status, or sexual orientation. -Printed on Recycled Paper Containing a Minimum of 10 Percent Post-Consumer Material- FOREWORD The Veterinary Diagnostic Laboratory (VDL) is a program of the College of Veterinary Medicine in the University of Minnesota Academic Health Center. The VDL was established in 1904 in the Agricultural Experiment Station of the University of Minnesota, by agreement between the Minnesota Livestock Sanitary Board and the University. It's purpose is to satisfy the need for accurate diagnosis of animal diseases that threaten Minnesota's livestock and poultry industries, companion animals, wildlife and human health. As the official laboratory of the Minnesota Board of Animal Health, the VDL provides laboratory support to the state's animal disease control and eradication programs. The VDL was administratively separated from the College's Department of Veterinary Diagnostic Medicine on July 1, 1998. This was done to enhance the interdisciplinary service and research through the participation of faculty across several non-traditional Collegiate and University departments. This year scientists in the VDL identified a new strain of influenza virus, subtype H3N2, in Minnesota swine herds. Collaborative research with St. Jude's Children Hospital led to a publication describing this virus, which is the frrst strain reported to have been derived by natural recombination of avian, human, and swine influenza viruses. Coinciding with the introduction and spread of H3N2 influenza, an epizootic of pseudorabies in swine lead to increased pseudorabies testing responsibilities for the VDL. New diagnostic tests for emerging and existing pathogens of livestock, poultry, and companion animals continue to be developed as part of the VDL mission. Serologic or molecular tests have been developed for swine influenza H3N2, avian pneumovirus, PRRS virus, Clostridium perfringens, porcine adenovirus, Clostridium dif.ficile, and porcine circovirus. BVD and Mycobacterium paratuberculosis polymerase chain reaction tests are in development. The VDL was fortunate this year to have recruited three highly skilled veterinary pathologists to occupy positions created by retirements. Cathy Carlson, Rod Frank, and Kurt Rossow bring internationally recognized expertise in surgical and bone pathology, food animal pathology and infectious disease diagnosis that will significantly strengthen the VDL's national and international recognition in these areas. On behalf of the Veterinary Diagnostic Laboratory faculty, staff and students, I thank the Minnesota Legislature, Minnesota Board of Animal Health, University of Minnesota, and animal organizations for their support. We look forward to continued improvements in laboratory services for the animal industries throughout the State. James E. Collins Director Acknowledgement is given to Mark Hinton, M.
