Predicting Novel Tick Vectors of Zoonotic Disease [PDF]

arXiv, 2016
With the resurgence of tick-borne diseases such as Lyme disease and the emergence of new pathogens such as Powassan virus, understanding what distinguishes vector from non-vector species, and predicting undiscovered tick vectors is an important step towards mitigating human disease risk.

Variable effects of wildlife and livestock on questing tick abundance across a topographical–climatic gradient

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract Large‐bodied wild ungulates are declining worldwide, while domestic livestock continue to increase in abundance. Such changes in large herbivore communities should have strong effects on the control of ticks and tick‐borne disease as they can indirectly modify habitat and directly serve as final hosts for ticks' lifecycles.

Neuropeptidergic control of the hindgut in the black-legged tick Ixodes scapularis [PDF]

International Journal for Parasitology, 2014
The hindgut, as a part of the tick excretory system, plays an important physiological role in maintaining homoeostases and waste elimination. Immunoreactive projections from the synganglion to the hindgut were found using antibodies against four different neuropeptides: FGLamide related allatostatin, myoinhibitory peptide, SIFamide, and orcokinin.

Geographic Variation in the Prevalence of Candidatus Neoehrlichia procyonis in Raccoons (Procyon lotor) in the United States and Canada

MicrobiologyOpen, Volume 14, Issue 1, February 2025.
A total of 167/394 (42.4%) raccoons were positive for Candidatus Neoehrlichia procyonis. Spatial variation was noted with higher prevalences in the Southeast region of the United States and in California. Ca. N. procyonis is widespread in raccoon populations, but the spatial variation in prevalence may be related to vector distribution or another ...

Evaluating acarological risk for exposure to Ixodes scapularis and Ixodes scapularis-borne pathogens in recreational and residential settings in Washington County, Minnesota

Ticks and Tick-borne Diseases, 2018
The distribution of I. scapularis, the tick vector of the bacteria that cause Lyme disease, has been expanding over the last two decades in the north-central United States in parallel with increasing incidence of human cases of Lyme disease in that region. However, assessments of residential risk for exposure to ticks are lacking from this region. Here,

Bartonella infections are rare in blood-fed Ixodes scapularis and Ixodes pacificus ticks collected from rodents in the United States

Parasites & Vectors
Background Ixodes scapularis and Ixodes pacificus are important vectors of multiple pathogens in the United States. However, their role in transmission of Bartonella spp., which are commonly reported in rodents and fleas, has been debated.

Historical Summary of Tick and Animal Surveillance Studies for Lyme Disease in Canada, 1975–2023: A Scoping Review

Zoonoses and Public Health, Volume 72, Issue 1, Page 9-22, February 2025.
ABSTRACT Introduction Lyme disease (LD) is caused by infection with the bacteria Borrelia burgdorferi sensu lato (Bb) through the bite of an infected Ixodes spp. tick. LD has emerged as a public and animal health issue in Canada, with human incidence increasing in part due to the expansion of Ixodes scapularis ticks and their vertebrate hosts.

An Ixodes scapularis cell line with a predominantly neuron-like phenotype [PDF]

Experimental and Applied Acarology, 2015
The Ixodes scapularis embryo-derived cell line ISE6 is the most widely utilized tick-derived cell line due to its susceptibility to a wide variety of tick- and non-tick-vectored pathogens. Little is known about its tissue origin or biological background. Protein expression of ISE6 cells was compared with that of another I. scapularis-derived cell line,

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

Journal 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.

Individual variation underlies large‐scale patterns: Host conditions and behavior affect parasitism

Ecology, Volume 106, Issue 1, January 2025.
Abstract Identifying the factors that affect host–parasite interactions is essential for understanding the ecology and dynamics of vector‐borne diseases and may be an important component of predicting human disease risk. Characteristics of hosts themselves (e.g., body condition, host behavior, immune defenses) may affect the likelihood of parasitism ...
