Researchers that reported Borrelia in the American dog tick

Possible strategies such as the collection of ticks, specifically the American dog tick
, Dermacentor variabilis (a known vector for tularemia), from animals upon entry into urban animal shelters and mapping of areas where the animals were found need to be considered if resources are limited.

Three ixodid tick species are important vectors in the United States: the American dog tick
(Dermacentor variabilis), the Rocky Mountain wood tick (D.
K9 Advantix([R]) is proven effective against the four most common ticks found on dogs in the United States: the Brown dog tick, vector of the organism that can cause ehrlichiosis; the American dog tick
