Dermacentor is a genus of ticks in the family Ixodidae, the hard ticks. The genus has a cosmopolitan distribution, with native species on all continents except Australia. Most occur in the Nearctic ecozone.[2]

Hosts of Dermacentor ticks include many large and small mammals, including horses, deer, cattle, lagomorphs, peccaries, porcupines, tapirs, desert bighorn sheep, and humans.[2] The American dog tick (D. variabilis) is a member of the genus.[3]

Dermacentor are vectors of many pathogens, including Rickettsia rickettsii, which causes the disease Rocky Mountain spotted fever, Coxiella burnetii, which causes Q fever, Anaplasma marginale, which causes anaplasmosis in cattle, Francisella tularensis, which causes tularemia, Babesia caballi, which causes equine piroplasmosis, and the Flavivirus that causes Powassan encephalitis.[2] Dermacentor ticks inject a neurotoxin that causes tick paralysis.[2]

Species

As of 2010, there are about 34 species in the genus.[4]
