Biographical Info

Dr. Peter J. Krause is Senior Research Scientist in the Department of Epidemiology and Public Health, 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 and 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 130 peer reviewed scientific publications. 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.

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

· Discover human infection by the relapsing fever spirochete Borrelia miyamotoi

They also 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.

International Activity

  • Tick-borne Disease Research
    Moscow, Russia; Obihiro, Japan(2010)
    We have collaborated with Russian scientists to describe the first human cases of Borrelia miyamotoi relapsing fever infection. We are continuing research collaboration to better define the epidemiology, ecology, clinical manifestations, pathogenesis, diagnosis and treatment of this infection. We are working with Japanese scientists to develop improved laboratory testing for the diagnosis of babesiosis, another emerging tick-borne infection.
