ROCKY MOUNTAIN WOOD TICK
Dermacentor andersoni
Feeds on: This species of tick will feed on pretty much anything it encounters, including horses, domestic cattle, wild goats and sheep, coyotes, porcupines, rabbits, grizzly bears, deer, moose, marmots, squirrels, various bird species, dogs, and humans.(1)
Pathogens transmitted: Carries tularaemia, Rocky Mountain spotted fever (Rickettsia rickettsii), Colorado tick fever, Powassan Virus, and causes tick paralysis.(1)
IXODES ANGUSTUS
Ixodes angustus
Feeds on: Wide distribution throughout Canada and the rest of North America makes this tick one of the most commonly encountered. Ixodes angustus typically feeds on rodents and small animals including cats and dogs, and though it is less common it is also known to bite humans.(1)
Pathogens transmitted: Carries and is a competent vector of Borrelia burgdorferi (Lyme disease), and Babesia microti.(1)
BLACKLEGGED TICK
AKA Deer Tick
Ixodes scapularis
Feeds on: This aggressive species of tick feeds on mice and other small rodents, a variety of birds, deer and other larger mammals; adult and nymph stages readily bite humans.(1)
Pathogens transmitted: As populations of this primary vector for Borrelia burgdorferi (Lyme disease) grow, Canadian Lyme risk zones are increasing, with highest prevalence in NS, QB and ON.(5) The blacklegged tick is also known to spread Anaplasma phagocytophilum (anaplasmosis), Babesia microti, Powassan Virus, Borrelia miyamotoi, Ehrlichia muris eauclarensis, and cause tick paralysis in dogs and other animals. Bartonella and Rickettsia strains have been found in the blacklegged tick, however, more research is required to prove they are competent vectors of these diseases in humans.(1)
IXODES SPINIPALPIS
Ixodes spinipalpis
Feeds on: Most commonly feeds on rats, pikas and other small nesting animals, but is known to bite a wide range of animals including birds and humans.(1)
Pathogens transmitted: Borrelia burgdorferi (Lyme disease), Borrelia bissetti, Babesia microti, human granulocytic ehrlichiosis/anaplasmosis, Powassan Virus, Borrelia genomospecies 2 (multiple strain genomic group within the B. burgdorferi s. l. complex).(1)(9)
LONE STAR TICK
Amblyomma americanum
Feeds on: Though it has been found in all provinces but SK, NB and PEI, significant populations of this species are not yet established in Canada. This very aggressive species of tick feeds on a wide variety of mammals and birds including coyotes, deer, and domestic animals, and is known to bite and transmit disease to humans (1)(2)(4).
Pathogens transmitted: human monocytic ehrlichiosis (HME) caused by Ehrlichia chaffeensis, Ehrlichia ewingii, tularaemia, southern tick-associated rash illness (STARI), tick paralysis, alpha-gal syndrome red meat allergy, Heartland virus disease, Bourbon virus disease. Though less common, lone star ticks also carry and spread Coxiella burnettii induced Q-fever, Rickettsia parkeri, Rickettsia amblyommii, and Panola Mountain ehrlichiosis. (1) (4)
RABBIT TICK
Haemaphysalis leporispalustris
Feeds on: As inferred from its common name this abundant species of tick most commonly feeds on rabbits and hares, however, it also feeds on a variety of birds, with less common accounts of feeding on larger mammals and humans.(1)
Pathogens transmitted: Rickettsia canadensis, Rocky Mountain spotted fever (Rickettsia rickettsii) Borrelia burgdorferi (Lyme disease), with the potential to disseminate other pathogens as a result of its association with birds regularly infested by blacklegged ticks.(1)
