Vector competence of Amblyomma americanum (Acari: Ixodidae) for Rickettsia rickettsii [PDF]

Ticks and Tick-borne Diseases, 2017
Rickettsia rickettsii - the etiologic agent of Rocky Mountain spotted fever (RMSF) - is widely spread across the Americas. In the US, Dermacentor spp. ticks are identified as primary vectors of R. rickettsii and Rhipicephalus sanguineus s.l. has been implicated in transmission of this pathogen in several locations in the Southwest. Conversely, ticks of

Assessing the underwater survival of two tick species, Amblyomma americanum and Amblyomma maculatum

Ticks and Tick-borne Diseases, 2019
The hard (ixodid) ticks Amblyomma americanum and Amblyomma maculatum are found throughout the southeastern United States. To study the effects of water inundation, which is an increasingly common phenomenon in many coastal areas, unfed adult A. americanum and A.

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

Predicting the potential distribution of Amblyomma americanum (Acari: Ixodidae) infestation in New Zealand, using maximum entropy-based ecological niche modelling

Experimental & applied acarology, 2020
Although currently exotic to New Zealand, the potential geographic distribution of Amblyomma americanum (L.), the lone star tick, was modelled using maximum entropy (MaxEnt). The MaxEnt model was calibrated across the native range of A.

Fine structure of tarsal sensilla in the tick Amblyomma americanum (L.) [PDF]

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1971
Selected tarsal bristles of the tick Amblyomma americanum (L.) (Acarina: Ixodidae; nymphal stage) were studied by means of scanning and transmission electron microscopy. All sensilla are multi-innervated and have thick cuticular walls containing either an elaborate pore canal system or a single slit opening at the tip.

Is Zebrafish a Good Model for the Alpha‐Gal Syndrome?

The FASEB Journal, Volume 39, Issue 9, 15 May 2025.
ABSTRACT The alpha‐Gal syndrome (AGS) is an underdiagnosed tick‐borne allergy characterized by both immediate and delayed IgE‐mediated anaphylactic reactions to the galactose‐alpha‐1,3‐galactose (alpha‐Gal) epitope. Common manifestations include gastrointestinal, cutaneous, and respiratory symptoms appearing 2–6 h after the consumption of mammalian ...
