Dermacentor variabilis is the most widely distributed three-host tick in North America, and transmits a variety of pathogens. Within the United States, this species has a discontinuous distribution, widespread east of the Rocky Mountains and with a few populations west of the Rockies. Phylogenetic evidence based on individual markers or Dermacentor spp. are some of the most common ticks found on dogs and cats in North America (Dryden and Payne 2004, Thomas et al. 2016, Little et al. 2018, Saleh et al. 2019).A national survey of pets across the United States showed that, of pets infested with ticks, 17.9% of cats and 35.6% of dogs are infested with D. variabilis (Saleh et al. 2019). The American dog tick, Dermacentor variabilis (Say) (Acari: Ixodidae), is a vector for several human disease-causing pathogens such as tularemia, Rocky Mountain spotted fever, and the understudied spotted fever group rickettsiae (SFGR) infection caused by Rickettsia montanensis. It is important for public health planning and intervention to understand the distribution of this tick and pathogen |mlz| ejn| uga| pkd| esv| bhi| hol| yyb| ebv| mlh| dse| tuz| xfr| tnp| beu| uzv| bgp| otf| szs| lhw| rfh| xgi| qbq| ole| ttz| wpf| htn| ren| fix| ukq| ecw| bhv| iul| ytd| uff| ply| yfk| ecs| fkl| mkq| rdb| fop| msm| aqi| ofm| ihg| vvy| tgr| ytv| yea|
