Dr. Peter J. Krause is Senior Research Scientist in the Department of Epidemiology and Public Health, Yale School of Public Health and Yale School of Medicine, New Haven, CT. He received his B.A. with honors in biology from Williams College and his M.D. from Tufts University School of Medicine. He completed his Pediatric internship and residency at Yale-New Haven Hospital and Stanford University Medical Center and his Pediatric Infectious Diseases training at the University of California Los Angeles (UCLA). He joined the faculty at the University of Connecticut in 1979 where he became Professor of Pediatrics and Chief of the Division of Pediatric Infectious Diseases. He moved to Yale in 2008.

Dr. Krause carries out translational, epidemiological, and clinical research in the study of vector-borne disease. His primary focus has been on human babesiosis but he has also carried out research on two companion tick-borne infections, Lyme disease and relapsing fever caused by Borrelia miyamotoi. He is the author of more than 160 peer reviewed scientific publications, 1 book, and 30 book chapters. He has served on the Editorial Board of the Journal of Clinical Microbiology and on several leadership committees of the Infectious Diseases Society of America and Connecticut Infectious Diseases Society.He has been cited in American Men and Women of Science, The Best Doctors in America, and Who’s Who in America.

Dr. Krause and his colleagues were the first to

Characterize the frequency and clinical outcome of human tick-borne disease coinfection

Identify the long-term persistence of Babesia infection in people

Perform an antibiotic treatment trial for human babesiosis

Characterize persistent and relapsing babesiois in immunocompromised hosts

Develop a laboratory method for screening the blood supply for Babesia microti infection

Discover human infection by the relapsing fever spirochete Borrelia miyamotoi

Discover human infection by Borrelia miyamotoi in the United States (co-discoverers)

Develop a Borrelia miyamotoi antibody assay

Describe the epidemiology of Borrelia miyamotoi infection

Provide evidence that Borrelia miyamotoi may be transmitted through blood transfusion

They also have quantitated the risk of transmission of babesiosis and Lyme disease though blood transfusion and developed several antibody and molecular-based tests for the diagnosis of babesiosis and Borrelia miyamotoi.
