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 ...

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 ...

Association between lone star tick bites and increased alpha-gal sensitization: evidence from a prospective cohort of outdoor workers

Parasites & Vectors, 2020
Background Alpha-gal is an oligosaccharide implicated in delayed anaphylaxis following red meat consumption. Exposure to tick bites has been correlated with development of an allergic response to alpha-gal.

Serpins in the Spotlight: Novel Bioinformatic Insights Into Hyalomma dromedarii Sialotranscriptome

Biochemistry Research International, Volume 2025, Issue 1, 2025.
Ticks pose a significant global threat to human and animal health as vectors of numerous pathogens, including bacteria, viruses, and parasites. Beyond their harmful impact, tick salivary glands contain serine protease inhibitors (serpins) known for their potential pharmaceutical properties.

Response to the Letter to the Editor by Rob Armstrong

Parasites & Vectors, 2017
In a recent Letter to the Editor, Armstrong raises concern that the design of the study reported by Six et al. was not consistent with the product label for treatment of Amblyomma americanum, since fluralaner was not re-administered 56 days after the ...

Alpha-Gal Syndrome after Ixodes scapularis Tick Bite and Statewide Surveillance, Maine, USA, 2014–2023

Emerging Infectious Diseases
In the United States, alpha-gal syndrome (AGS) is primarily associated with lone star tick (Amblyomma americanum) bites. We describe AGS onset after an Ixodes scapularis tick bite and present AGS surveillance in Maine, 2014–2023.

Blood Meal Analysis to Identify Reservoir Hosts for Amblyomma americanum Ticks

Emerging Infectious Diseases, 2010
Efforts to identify wildlife reservoirs for tick-borne pathogens are frequently limited by poor understanding of tick–host interactions and potentially transient infectivity of hosts under natural conditions.

Alpha-Gal Allergy: a new threat to Appalachia

Marshall Journal of Medicine, 2021
Alpha-gal allergy, or mammalian meat allergy, is described as the development of IgE antibodies to the oligosaccharide galactose-a-1,3-galactose following a bite from the tick species Amblyomma americanum (Lone Star tick) or Dermacentor variabillis (Wood
