Model predicts where ticks, Lyme disease will appear next in Midwest states
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. They used these data - along with an analysis of county-level landscape features associated with the spread of ticks - to build a model that can predict where ticks are likely to appear in future years. (2020-12-22)

A gene from ancient bacteria helps ticks spread Lyme disease
One reason ticks spread Lyme disease so well goes back to a unique evolutionary event. Researchers reporting in the journal Cell on December 10, 2020 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. Ticks acquired the gene for this enzyme 40 million years ago from an unknown species of ancient bacteria. (2020-12-10)

Lyme disease ticks produce antibiotic that protects them from human skin bacteria
Ticks live dangerous lives, spending most of their time questing for a host across wildly different habitats and seasons. Once they encounter a reptile, bird, or a mammal like us, they become intimately connected with it -- and all of its bacteria and viruses -- for days on end. Though ticks are notorious for transmitting pathogens such as the Lyme disease bacterium, how does their immune system keep them safe from contracting pathogens themselves? (2020-12-10)

Yale scientists identify protein that protects against Lyme
Yale researchers have discovered a protein that helps protect hosts from infection with the tick-borne spirochete that causes Lyme Disease, a finding that may help diagnose and treat this infection, they report Nov. 11 in the journal PLOS Pathogens. (2020-11-11)
