HME occurs in California in " Ixodes pacificus " ticks and in " Dermacentor variabilis " ticks . Nearly 600 cases were reported to the CDC in 2006.
2.
By this approach, he was able to identify the tick responsible for what he called Nantucket fever " ( it was not " Dermacentor variabilis ", the dog tick, as alleged by other investigators ) and to point to the white-footed mouse as the pathogen's reservoir . ( Later, deer ticks were shown to be the vector of Lyme disease .)
3.
The Dermacentor ticks, " Dermacentor andersonii " and " Dermacentor variabilis " are also vectors of the POWV . There are a total of 6 known species of tick that act as vectors, with " Ixodes cookei " being the predominant species in Canada and the Northeastern United States and " Ix . scapularis " as a significant vector in Minnesota and Wisconsin.
4.
Lyme disease, or borreliosis, is caused by " Borrelia burgdorferi " and spread by " Ixodes pacificus " on the West coast of the United States and by " Rickettsia rickettsii ", which causes Rocky Mountain spotted fever, are both spread by the American dog tick, " Dermacentor variabilis ", and the brown dog tick, " Rhipicephalus sanguineous ".
5.
The primary vectors for " Borrelia burgdorferi " are the deer tick " Ixodes scapularis " in Eastern parts of the United States, " Ixodes pacificus " in California and Oregon, and " Ixodes ricinus " in Europe . " Dermacentor variabilis " may also carry " Anaplasma phagocytophilum ", the causative agent of HGE ( human granulocytic ehrlichiosis ), and " Ehrlichia chaffeensis ", the causative agent of HME ( human monocytic ehrlichiosis ).
6.
Other genera with species that are often of high local importance to domestic animals include these examples : " Ixodes " ( " Ixodes ricinus ", the deer tick of Europe; " Ixodes scapularis ", the black-legged tick of North America; " Ixodes holocyclus ", the paralysis tick of Australia ) . " Haemaphysalis " ( " Ha . leachii ", the yellow dog tick of the tropics ) . " Dermacentor " ( " Dermacentor andersoni ", the Rocky Mountain wood tick; " Dermacentor variabilis ", the American dog tick; " D . reticulatus ", the ornate dog tick of Europe ) . " Dermacentor nitens " the tropical horse tick of the Americas has a one-host lifecycle similar to the boophilids . " Margaropus winthemi ", the beady-legged tick, infests horses and cattle in South Africa.
