RECOGNITION

BIOLOGY
Importance
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. Dermacentor ticks inject a neurotoxin that causes tick paralysis.
Range
The genus has a cosmopolitan distribution, with native species on all continents except Australia. Most occur in the Nearctic ecozone.
