Anomalous morphologies in Ixodes scapularis feeding on human hosts

Ticks and Tick-borne Diseases, 2022
Cases of anomalous morphologies in the blacklegged tick, Ixodes scapularis, have been reported in both field-collected and human-biting specimen in the Northeastern and Midwestern United States, complicating the identification of this medically important tick species. We herein describe four cases of morphological anomalies in I.

Microbiome Composition and Borrelia Detection in Ixodes scapularis Ticks at the Northwestern Edge of Their Range

Tropical Medicine and Infectious Disease, 2020
Lyme disease-causing Borrelia burgdorferi has been reported in 10–19% of Ixodes ticks from Alberta, Canada, where the tick vector Ixodes scapularis is at the northwestern edge of its range.

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

Medical and Veterinary Entomology, EarlyView.
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.

Molecular characterization of novel sulfotransferases from the tick, Ixodes scapularis [PDF]

BMC Biochemistry, 2011
Ixodes scapularis, commonly known as the blacklegged or deer tick, is the main vector of Lyme disease in the United States. Recent progress in transcriptome research has uncovered hundreds of different proteins expressed in the salivary glands of hard ticks, the majority of which have no known function, and include many novel protein families.

Gaps and opportunities in on‐host winter tick (Dermacentor albipictus) surveillance in North America

The Journal of Wildlife Management, Volume 89, Issue 4, May 2025.
The investigation and management of the impacts of winter tick infestations on moose in North America necessitates coordinated surveillance and intervention efforts. The current absence of searching for winter ticks on other potential ungulate hosts, largely based on historical beliefs of predilection from limited captive studies, has created a ...

Dynamics of Insulin Signaling in the Black-Legged Tick, Ixodes scapularis [PDF]

Frontiers in Endocrinology, 2019
Insulin-like peptides (ILPs) have been identified in several invertebrates, particularly insects, and work on these ILPs has revealed many roles including regulation of energy homeostasis, growth, development, and lifespan to name a few. However, information on arthropod ILPs outside of insects is sparse.

The Release of Non‐Native Gamebirds Is Associated With Amplified Zoonotic Disease Risk

Ecology Letters, Volume 28, Issue 4, April 2025.
Spillback is potentially an important mechanism by which non‐natives contribute to zoonotic disease emergence. We capitalise on quasi‐experimental releases of non‐native pheasants (Phasianus colchicus) to compare native pathogen prevalence between sites with similar local conditions but different non‐native densities. Prevalence of Borrelia sp.

mRNA vaccination of rabbits alters the fecundity, but not the attachment, of adult Ixodes scapularis

Scientific Reports
19ISP is a nucleoside-modified mRNA-lipid nanoparticle vaccine that targets 19 Ixodes scapularis proteins. We demonstrate that adult I. scapularis have impaired fecundity when allowed to engorge on 19ISP-immunized rabbits.
