NEWVEC research at UMass Amherst may lead to strategies to reduce the incidence of tick-borne illness

As tick season kicks in across the country, the executive director of the University of Massachusetts Amherst-based New England Center of Excellence in Vector-Borne Diseases (NEWVEC) and his team have completed research that offers a promising lead in the fight against Lyme disease.

The study, published recently in the journal Vector-borne and Zoonotic Diseases, demonstrates that the blood of the white-tailed deer kills the corkscrew-shaped bacterium that causes Lyme disease, a potentially debilitating illness. The Centers for Disease Control and Prevention (CDC) estimates that each year some 476,000 people are diagnosed with and treated for Lyme, the most common vector-borne disease in the U.S.

“Deer are vitally important to the survival of deer ticks, but they are not involved with transmitting the Lyme bacteria, Borrelia burgdorferi,” explains senior author Stephen Rich, professor of microbiology. “We’ve known for some time that ticks taken from white-tailed deer are not infected, and we speculated that something about the deer prevented those ticks from becoming infected. But until publication of our paper, no one had done the experiment to show that deer blood – specifically the serum component of white-tailed deer blood – kills Lyme.”

The results of the study may one day lead to new strategies and approaches for Lyme disease prevention and treatment, says lead author Patrick Pearson, a Ph.D. student in NEWVEC, whose upcoming doctoral examination focuses in part on this research.
