Genetic engineering for the public good? No one’s suggesting that, but researchers have found a way to genetically engineer the tick-borne bacteria that causes Lyme disease in humans so that it can’t infect mice.

Researchers at the division of Vector-Borne Infectious Diseases, Centers for Disease Control and Prevention in Fort Collins, Colo., deactivated a gene in the bacteria, called Borrelia burgdorfer, and created a strain that was much less capable of spreading Lyme disease.
