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. [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 species 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]
As of 2025, 43 species are placed in the genus: [4]
