Impacts of Deciduous Leaf Litter and Snow Presence on Nymphal Ixodes scapularis (Acari: Ixodidae) Overwintering Survival in Coastal New England, USA

open access: yesInsects, 2019
Blacklegged ticks (Ixodes scapularis Say) are the vector for pathogens that cause more cases of human disease than any other arthropod. Lyme disease is the most common, caused by the bacterial spirochete Borrelia burgdorferi (Johnson, Schmid, Hyde ...

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, Volume 308, Issue 9, Page 2413-2432, September 2025.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Tick phenology, tick-host associations, and tick-borne pathogen surveillance in a recreational forest of East Texas, USA.

open access: yesPLoS ONE
Management of tick-borne disease necessitates an understanding of tick phenology, tick-host associations, and pathogen dynamics. In a recreational hotspot outside of one of the largest cities in the United States, we conducted a year of monthly ...

Evidence for Geographic Variation in Life-Cycle Processes Affecting Phenology of the Lyme Disease Vector Ixodes scapularis (Acari: Ixodidae) in the United States

open access: yesJournal of medical entomology, 2018
The seasonal activity pattern of immature Ixodes scapularis Say (Acari: Ixodidae) varies geographically in the United States, which may affect the efficiency of transmission cycles of pathogens transmitted by this species.

Effects of temperature on bacterial microbiome composition in Ixodes scapularis ticks

open access: yesMicrobiologyOpen, 2018
Ixodes scapularis, the blacklegged deer tick, is the principal vector of Lyme disease in North America. Environmental factors are known to influence regional and seasonal incidence of Lyme disease and possibly the endemicity of the disease to the ...

Efficacy of afoxolaner against Ixodes scapularis ticks in dogs

open access: yesVeterinary Parasitology, 2014
Efficacy of afoxolaner, a novel isoxazoline insecticide/acaricide, against Ixodes scapularis was evaluated in a laboratory study. One day prior to treatment, beagle dogs (n=16) were infested with 50 unfed wild adult ticks. Repeat infestations were performed weekly for four additional weeks.

Contrasting epigenetics of Ixodes scapularis populations

open access: yes
Abstract Hard ticks are a source of public health concern, in part due to their ability to inhabit different environmental regions, which increases human encounters. In the United States (US), blacklegged ticks (Ixodes scapularis Say), the primary vector of Lyme disease, exhibit various phenotypes depending on their geographic origin (i.e ...

Prevalence and Genetic Characterization of Deer Tick Virus (Powassan Virus, Lineage II) in Ixodes scapularis Ticks Collected in Maine.

open access: yesAmerican Journal of Tropical Medicine and Hygiene, 2019
Deer tick virus (DTV) is a genetic variant of Powassan virus (POWV) that circulates in North America in an enzootic cycle involving the blacklegged or "deer tick," Ixodes scapularis, and small rodents such as the white-footed mouse.
