Lyme disease-carrying ticks may invade new territory in the Midwest

Black-legged ticks may soon expand their territory across the midwestern U.S., carrying Lyme disease with them, a new study finds.  The study researchers created a timeline of when and where the black-legged tick (Ixodes scapularis) has spread since the 1960s, when the parasitic arachnid was first detected in Wisconsin and Minnesota. The team pinpointed several […]

Model predicts where ticks, Lyme disease will appear next in Midwest states

Entomology professor Brian Allan and his colleagues built a model that can accurately predict future occurrences of black-legged ticks in the Midwest. Credit: L. Brian Stauffer By drawing from decades of studies, scientists created a timeline marking the arrival of black-legged ticks, also known as deer ticks, in hundreds of counties across 10 Midwestern states.

A gene from ancient bacteria helps ticks spread Lyme disease — ScienceDaily

One of the reasons ticks spread Lyme disease so well goes back to a unique evolutionary event. Researchers reporting in the journal Cell on December 10 have discovered that an antibacterial enzyme in ticks, Dae2, protects them from bacteria found on human skin, while still allowing them to harbor Borrelia burgdorferi, the bacterium that causes […]

Lyme Disease and the Dangers of the Forest Edge

Lyme disease was first identified in 1976 in Lyme, Conn. Since then, the disease has become more common in North America, spreading throughout the northeastern and midwestern United States, creeping north into Canada and south into Virginia. About 30,000 cases are reported each year, although it’s estimated that the true prevalence of the […]
