The genome of the American dog tick (Dermacentor variabilis). [PDF]

G3 (Bethesda)
Abstract The American dog tick (Dermacentor variabilis) is a vector of zoonotic pathogens in North America that poses emerging threats to public health. Despite its medical importance, genomic resources for D. variabilis remain scarce. Leveraging long-read nanopore sequencing, we generated a high-quality genome assembly for D. variabilis

Spatial and temporal analyses of Dermacentor variabilis (Say) (Acari: Ixodidae) in central and eastern Canada. [PDF]

Med Vet Entomol
One thousand one hundred ninety‐eight adult Dermacentor variabilis (Say), a species of veterinary and human medical importance, were collected from companion animals in central and eastern Canada. Peaks in adult D. variabilis submissions occurred in May and June across the provinces. Most submissions of adult D.

Dermacentor variabilis: An Unusual foreign body of the external ear canal

Otolaryngology Case Reports, 2020
This case helps identify common aural foreign bodies in the pediatric population, understand the management of aural foreign bodies, and reviews special considerations that should be made with a tick as an aural foreign body. This is a case report of one

Determining the photic chronotype in locomotor activity and levels of endogenous control in the American dog tick (Dermacentor variabilis)

Ticks and Tick-Borne Diseases
It is an open question whether the activity of host-seeking ticks is under endogenous circadian control or arises entirely as an exogenous response to external stimuli.

Applying MALDI-TOF MS to resolve morphologic and genetic similarities between two Dermacentor tick species of public health importance [PDF]

Scientific Reports
Hard ticks (Acari: Ixodidae) have been historically identified by morphological methods which require highly specialized expertise and more recently by DNA-based molecular assays that involve high costs.

Nonrandom distribution of vector ticks (Dermacentor variabilis) infected by Francisella tularensis. [PDF]

PLoS Pathogens, 2009
The island of Martha's Vineyard, Massachusetts, is the site of a sustained outbreak of tularemia due to Francisella tularensis tularensis. Dog ticks, Dermacentor variabilis, appear to be critical in the perpetuation of the agent there. Tularemia has long
