Automated identification of spotted‐fever tick vectors using convolutional neural networks

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 829-841, December 2025.
We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.

Prevalence of Rickettsiales in ticks removed from the skin of outdoor workers in North Carolina

Parasites & Vectors, 2014
Background Tick-transmitted rickettsial diseases, such as ehrlichiosis and spotted fever rickettsiosis, are significant sources of morbidity and mortality in the southern United States.

Zoonotic Disease Transmission May Be Linked to Host Co‐Occurrence Network Topology

Annals of the New York Academy of Sciences, Volume 1554, Issue 1, Page 110-120, December 2025.
A global analysis of zoonotic host co‐occurrence networks identified 22 networks from five continents (A) and 87 hosts from 16 orders of mostly birds but also mammals (B) as having a high potential for disease transmission. ABSTRACT Most human pathogens are zoonotic, transmitted from vertebrate hosts to humans.

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

Global trend of food‐induced anaphylaxis: Up to date

Pediatric Allergy and Immunology, Volume 36, Issue 12, December 2025.
Abstract This review examines the evolving global landscape of food‐induced anaphylaxis (FIA), revealing critical epidemiological shifts that challenge traditional allergen management paradigms. As the leading cause of anaphylaxis worldwide, FIA demonstrates striking geographic, age‐specific, and temporal patterns that reflect broader changes in ...

Carryover Effects of Thermal Conditions on Tick Survival, Behavior, and Simulated Detectability

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Recent thermal history affects the abundance and behavior of adult Amblyomma americanum. Thermal responses impacted simulated tick detection through combined effects on movement and mortality. ABSTRACT Carryover effects occur when environmental history of an organism influences its behavior, fitness, and population dynamics.

Extracellular Vesicles in Arthropods: Biogenesis, Functions, Isolation Methods and Applications

Journal of Extracellular Vesicles, Volume 14, Issue 9, September 2025.
ABSTRACT Extracellular vesicles (EVs) are membrane‐bound nanoparticles secreted by cells that are involved in multiple forms of intercellular communication and show promising potential for biotechnological applications. Arthropod‐derived EV research remains relatively fragmented in contrast to the extensively studied mammalian EV field. In this review,

Identification of Alpha-Gal glycolipids in saliva of Lone-Star Tick (Amblyomma americanum)

Ticks and Tick-Borne Diseases
Alpha-Gal Syndrome (AGS) is a delayed allergic reaction triggered by IgE antibodies targeting galactose-α-1,3-galactose (α-gal), prevalent in red meat.

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.

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
