Ixodes is a genus of hard-bodied ticks (family Ixodidae). It includes important disease vectors of animals and humans (tick-borne disease), and some species (notably Ixodes holocyclus) inject toxins that can cause paralysis. Some ticks in this genus may transmit the pathogenic bacterium Borrelia burgdorferi [3] responsible for causing Lyme disease.
