Double Trouble: Scientist Find Second Pathogen Related to Lyme Disease

Mar 2, 2016

A nymph-stage, black legged tick is shown on a piece of clothing in Brewster. Black legged ticks are born disease-free. But they acquire the bacterium that causes Lyme disease when they feed on an infected mammal. Scientists have now identified a second bacterium that's also related to Lyme.

When you hear "Lyme disease" you most likely think of ticks. But the source of the disease is actually a bacterium that lives inside the tick; the tick picks up the bacterium when it feeds on infected mammals like white-footed mice.

Scientists at the Mayo Clinic recently discovered another bacterium that causes Lyme. Kathryn Eident spoke with UMass Amherst microbiologist Stephen Rich about the discovery.
