Afebrile spotted fever group Rickettsia infection after bite from a Dermacentor variabilis
tick infected with Rickettsia montanensis.
The American dog tick, Dermacentor variabilis
, and, to a lesser extent, Amblyomma americanum transmit infection in Eastern and Southern U.
Virome analysis of Amblyomma americanum, Dermacentor variabilis
, and Ixodes scapularis ticks reveals novel highly divergent vertebrate and invertebrate viruses.
Repellent properties of glade savory, Clinopodium glabellum, against the American dog tick, Dermacentor variabilis
chaffeensis in other tick species, including the dog tick, Dermacentor variabilis
(18,22,23), the western black-legged tick, Ixodes pacificus (22), Ixodes ricinus in Russia (24), and the ticks A.
Three species of ticks, including Amblyomma americanum, Dermacentor variabilis
, and Ixodes scapularis were collected from animals as well as from public areas by flagging vegetation in 25 different counties in order to determine areas of greatest risk.
Key words: Didelphis virginiana, Procyon lotor, Mephitis mephitis, Dermacentor variabilis

Primary vectors are Dermacentor variabilis
(Say) (American dog tick) in the eastern U.
The most common tick species submitted were Amblyomma americanum, followed by Dermacentor variabilis
Notably, while investigating a tick-borne outbreak of presumed type B infections in South Dakota, Markowitz and colleagues found evidence of both type A and type B strains in Dermacentor variabilis
ticks collected from dogs (14).
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.
scapularis and 2 adult Dermacentor variabilis
from tick-endemic sites.
Specificity was also evaluated with DNA (2 [micro]L) extracted as previously described from Francisella-like tick endosymbionts of Dermacentor variabilis
and Francisella-like soil bacteria (online Appendix) (9,10).
Genotypic diversity of Francisella tularensis infecting Dermacentor variabilis
ticks on Martha's Vineyard, Massachusetts.
texanus, Dermacentor variabilis
, and Amblyomma maculatum, comprised the remaining 1% and were omitted from further analysis.
