The Ixodes tick

Species

There are hundreds of species of ticks found throughout the world, but the Ixodes tick is the primary vector responsible for transmitting the Borrelia burgdorferi bacteria, the actual cause of Lyme disease.

The Ixodes tick

There are established populations of the tick that transmits Lyme disease in Canada. Though western blacklegged ticks are widely distributed in British Columbia, populations are largest in the lower mainland, on Vancouver Island and in the Fraser Valley. Established populations of blacklegged ticks, on the other hand, have been found in southeastern Quebec, southern and eastern Ontario, southeastern Manitoba and parts of New Brunswick and Nova Scotia.

Blacklegged ticks can be found in many areas of Canada, even where tick populations have not been identified. These ticks are introduced into these areas by migratory birds. About 10 percent of these ticks are infected with the Lyme disease bacterium.1

Ixodes and other species of ticks transmit more than just Lyme disease to dogs and humans, including:

  • Anaplasmosis
  • Ehrlichiosis
  • Babesiosis
  • Rocky Mountain spotted fever
