Spotted-Fever Group Rickettsia in Dermacentor variabilis, Maryland [PDF]
Emerging Infectious Diseases, 2004 Three-hundred ninety-two adult Dermacentor variabilis were collected from six Maryland counties during the spring, summer, and fall of 2002. Infection prevalence for spotted fever group Rickettsia was 3.8%, as determined by polymerase chain reaction ...

Powassan Virus Lineage I in Field-Collected Dermacentor variabilis Ticks, New York, USA [PDF]
Emerging Infectious Diseases, 2023 Powassan virus is a tickborne flavivirus that can cause lethal or debilitating neurologic illness. It is canonically transmitted by Ixodes spp. ticks but might spill over to sympatric Dermacentor species. We detected Powassan virus lineage I from a pool

Spatial repellents transfluthrin and metofluthrin affect the behavior of Dermacentor variabilis, Amblyomma americanum, and Ixodes scapularis in an in vitro vertical climb assay. [PDF]
PLoS ONE, 2022 Repellents serve an important role in bite protection. Tick repellents largely rely on biomechanisms that induce responses with direct contact, but synthetic pyrethroids used as spatial repellents against insects have received recent attention for ...

Comparative vertical transmission of Rickettsia by Dermacentor variabilis and Amblyomma maculatum. [PDF]
Ticks Tick Borne Dis, 2017 The geographical overlap of multiple Rickettsia and tick species coincides with the molecular detection of a variety of rickettsial agents in what may be novel tick hosts. However, little is known concerning transmissibility of rickettsial species by various tick hosts.
