“Hot spots” for blacklegged ticks found in Canada

The blacklegged tick (Ixodes Scapularis), otherwise known as the deer tick, has been expanding throughout Canada. The tick, which harbors Borrelia burgdorferi sensu stricto, the bacteria causing Lyme disease, is finding its way into new regions, thanks to climate change, according to Lieske and colleagues from Mount Allison University in New Brunswick, Canada.
