''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. Hosts of ''Dermacentor'' ticks include many large and small mammals, including horses, deer, cattle, lagomorphs, peccaries, porcupines, tapirs, desert bighorn sheep, and humans.〔 The American dog tick (''D. variabilis'') is a member of the genus. ''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.〔 ==Species== As of 2010, there are about 34 species in the genus. *''Dermacentor abaensis'' Teng, 1963 *''Dermacentor albipictus'' (Packard, 1869) *''Dermacentor andersoni'' Stiles, 1908 *''Dermacentor asper'' Arthur, 1960 *''Dermacentor atrosignatus'' Neumann, 1906 *''Dermacentor auratus'' Supino, 1897 *''Dermacentor circumguttatus'' Neumann, 1897 *''Dermacentor compactus'' Neumann, 1901 *''Dermacentor confragus'' (Schulze, 1933) *''Dermacentor dispar'' Cooley, 1937 *''Dermacentor dissimilis'' Cooley, 1947 *''Dermacentor everestianus'' Hirst, 1926 *''Dermacentor filippovae'', Apanaskevich & Apanaskevich, 2015〔Dmitry A.
