Dr. Jeffrey Stott is a Professor of Microbiology and Immunology at the University of California, Davis. Dr. Stott studies the cause of an unusual tick-borne disease localized in cattle in California. Epizootic Bovine Abortion is caused by bacteria that cannot be grown in the laboratory, which has hampered the development of vaccines against this disease that leads to up to 5-10% of all cattle abortions in California. Dr. Stott discusses the search for an effective vaccine, as well as his interest in studying diseases in sea mammals like sea lions and dolphins.
