Scientists hope to use genetic engineering to reduce the transmission of Lyme disease. The scientists’ target is not the deer and ticks associated with the disease, but wild, White-footed mice, the main carriers of Lyme. The teams of scientists are engineering changes in the genetic makeup of the mice by adding a gene for an antibody that prevents Lyme infection to a mouse embryo.
