The Immunology of Alpha‐Gal Syndrome: History, Tick Bites, IgE, and Delayed Anaphylaxis to Mammalian Meat

Immunological Reviews, Volume 332, Issue 1, July 2025.
ABSTRACT The primary features of the alpha‐gal syndrome (AGS) are (i) The IgE ab that are causally related to anaphylaxis with infusions of Cetuximab are specific for galactose alpha‐1,3‐galactose. (ii) In the USA, this IgE ab is induced by bites of the tick Amblyomma americanum. (iii) The anaphylactic reactions to food derived from non‐primate mammals

Modulation of the tick gut milieu by a secreted tick protein favors Borrelia burgdorferi colonization

Nature Communications, 2017
Borrelia burgdorferi, the causative agent of Lyme disease, is transmitted by the tick Ixodes scapularis. Here, the authors show that a tick secreted protein (PIXR) modulates the tick gut microbiota and facilitates B. burgdorferi colonization.

Potential Role of Deer Tick Virus in Powassan Encephalitis Cases in Lyme Disease–endemic Areas of New York, USA

Emerging Infectious Diseases, 2013
Powassan virus, a member of the tick-borne encephalitis group of flaviviruses, encompasses 2 lineages with separate enzootic cycles. The prototype lineage of Powassan virus (POWV) is principally maintained between Ixodes cookei ticks and the groundhog ...

Parasite spatial distribution shapes parasite aggregation on host populations, but not at high parasite density

Ecosphere, Volume 16, Issue 6, June 2025.
Abstract Spatial aggregation of environmental or trophically transmitted parasites has the potential to influence host–parasite interactions. The distribution of parasites on hosts is one result of those interactions, and the role of spatial aggregation is unclear.

The distribution of Babesia odocoilei in Ixodes species ticks in Canada: Implications for one health surveillance

Ticks and Tick-Borne Diseases
Ixodes scapularis and Ixodes pacificus are vectors of a range of pathogens of public health significance in North America. These ticks transmit pathogens to and from wild animal reservoir host species, but also bite humans and expose them to the ...

Ixodes Immune Responses Against Lyme Disease Pathogens

Frontiers in Cellular and Infection Microbiology, 2018
Although Ixodes scapularis and other related tick species are considered prolific vectors for a number of important human diseases, many aspects of their biology, microbial interactions, and immunity are largely unknown; in particular, how these ancient ...

Are ticks venomous animals? [PDF]

, 2017
[Introduction]: As an ecological adaptation venoms have evolved independently in several species of Metazoa. As haematophagous arthropods ticks are mainly considered as ectoparasites due to directly feeding on the skin of animal hosts. Ticks are of major

Permission to bite: White‐footed mice show no increased grooming response to tick infestation

Journal of Zoology, Volume 326, Issue 2, Page 140-147, June 2025.
White‐footed mice (Peromyscus leucopus) are one of the most frequently studied hosts of blacklegged ticks (Ixodes scapularis); however, interactions between white‐footed mice and ticks are not easily observed. This study aimed to quantify activity patterns in white‐footed mice and to assess their behavioral responses to parasitism by blacklegged ticks ...
