Dr. Willy Burgdorfer, born on June 27, 1925, in Basel, Switzerland, is known for transforming the understanding of tick-borne illnesses.
Burgdorfer pursued his undergraduate and doctoral studies in parasitology and tropical bacteriology at the University of Basel – where he first developed his fascination with ticks while studying how these arthropods transmitted spirochetes that caused relapsing fever. In 1951, Burgdorfer moved to the United States for a fellowship in Montana at the Rocky Mountain Laboratories (RML) – a National Institute of Health biomedical research facility for vector-borne diseases, such as Rocky Mountain spotted fever, Lyme disease and Q fever.
Burgdorfer’s most significant scientific contribution came in 1981 when the New York State Department of Health sent deer ticks from Long Island to his laboratory, suspecting cases of Rocky Mountain spotted fever. Like many times before, Burgdorfer dissected the ticks and stained cells from their gut to examine them for rickettsia bacteria. Instead of the short, rod-shaped bacteria that cause spotted fever, he found long, slender, corkscrew-shaped spirochetes – bacteria he had first studied 30 years earlier as a graduate student.
Burgdorfer suspected these spirochetes could be responsible for Lyme disease, a mysterious illness that had been baffling scientists since it was first recognized in children in Connecticut in the 1970s. He published his further findings in Science in 1982, which identified Borrelia burgdorferi (named in his honor) as the bacterium responsible for Lyme disease.
Aside from his work with Lyme disease, Burgdorfer helped to map the geography of diseases like Rocky Mountain spotted fever and advocated for public education on the importance of preventing tick-borne diseases.
Although retiring in 1986, Burgdorfer continued his association with the Rocky Mountain Laboratories’ Laboratory of Human Bacterial Pathogenesis as scientist emeritus. He was also active on the Scientific/Medical Advisory Committee of the Lyme Disease Foundation.
Dr. Willy Burgdorfer passed away on November 17, 2014.
