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)

Dermacentor_variabilis american dog tick

AMERICAN DOG TICK

Dermacentor variabilis

Feeds on: Typically feeds on mid-sized mammals including dogs, raccoons, porcupines and black bears, and also readily feeds on humans.(1)
Pathogens transmitted: Though the potential for contracting a tick-borne disease from this species is thought to be relatively low, it is known to carry Borrelia burgdorferi (Lyme disease), tularaemia, Rocky Mountain spotted fever, and cause tick paralysis. It is also known to infect wild and domestic cats with the fatal protozoan Cytauxzoon felis, and horses with equine piroplasm, Babesia caballi, and Ehrlichia risticii, the causative agent of Potomac horse fever.(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)

GROUNDHOG TICK

Ixodes cookei

Feeds on: Wide distribution throughout Canada  makes this tick one of the most commonly encountered. The groundhog tick typically feeds on groundhogs/woodchucks and other small animals including cats and dogs, and though less common, is also known to bite humans.(1)
Pathogens transmitted: Powassan virus, filarial nematodes, carries but is not indicated to be a competent vector of Borrelia burgdorferi (Lyme disease).(3)

SQUIRREL TICK

Ixodes marxi

Feeds on: Most commonly feeds on squirrels and smaller animals including hares, however, there are numerous records for this tick biting cats, dogs and humans.(1)
Pathogens transmitted: Powassan Virus (1)

Mouse Tick.jpg

MOUSE TICK

Ixodes muris

Feeds on: This tick typically feeds on mice and other small mammals, though it is also known to feed on migratory birds, cats, dogs and humans.(1)
Pathogens transmitted: Competent vector for Babesia microti, and carries but is a relatively weak vector for Borrelia burgdorferi. Causes a noninfectious, severe inflammatory reaction in domestic animals and several other mammalian species, and humans to a lesser degree.(1)(7)

Rhipicephalus_sanguineus brown dog tick.

BROWN DOG TICK

Rhipicephalus sanguineus

Feeds on: Though this species primary feeds on dogs, it is known to bite a wide variety of hosts, opportunistically encountering humans and other domestic animals associated with dogs.(1)(6)
Pathogens transmitted: The brown dog tick is a known vector of numerous pathogens including canine ehrlichiosis (Ehrlichia canis), canine babesiosis (Babesia canis vogeli), and canine hepatozoonosis (Hepatozoon canis) in dogs, as well as Rocky Mountain spotted fever (Rickettsia rickettsii), and tick bite fever (Rickettsia conorii) in humans.(1)(6)

Amblyomma_americanum lone star.jpg

LONE STAR TICK

Amblyomma americanum

Feeds on: Though it has been found in all provinces but SK, NB and PE, 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)

RACCOON TICK

Ixodes texanus

Feeds on: This tick typically feeds on raccoons, but are also known to bite squirrels and dogs.(1)
Pathogens transmitted: Strains of Babesia, Rickettsia rickettsii,  and Ehrlichiae; also carries Borrelia burgdorferi (Lyme disease)though vector competency is unclear at this time.(1)(8)
