UT studies blacklegged ticks to explain variations in Lyme disease risk

The University of Tennessee is taking part in a $2.5 million study aimed at shedding new light on the blacklegged tick, the parasite responsible for spreading Lyme disease.

The project marks the first time scientists have taken a systematic, regionwide look at the blacklegged tick – also called the deer tick – to determine how factors like climate and tick genetics affect the bacterium (Borrelia burgdorferi) that causes the disease.
