New building to advance study of tuberculosis in cattle, wildlife

Two veterinarians who study tuberculosis can’t wait to move their research into the new high-containment large animal facility at the National Centers for Animal Health in Ames, Iowa.

Even before the dedication, Drs. Mitchell V. Palmer and W. Ray Waters relocated some white-tailed deer to the premises so the animals could acclimate—and help showcase the special cervid rooms.

The veterinary medical officers work for the U.S. Department of Agriculture, which began tuberculosis research in 1992 to respond to an increasing prevalence of the disease in cattle. Dr. Palmer said the main objectives are to improve diagnostic tests for Mycobacterium bovis, to explore the immunopathogenesis of the infection, and to develop vaccines. The researchers study tuberculosis in cattle and white-tailed deer as well as elk, reindeer, and raccoons.

The program to eradicate tuberculosis in cattle dates to 1917, Dr. Palmer said. Prior to the pasteurization of milk, M bovis accounted for about 25 percent of the cases of tuberculosis in humans.
