Relative Risk for Ehrlichiosis and Lyme Disease in an Area Where Vectors for Both Are Sympatric, New Jersey, USA

Emerging Infectious Diseases, 2017
The lone star tick, Amblyomma americanum, is a vector of Ehrlichia chaffeensis and E. ewingii, causal agents of human ehrlichiosis, and has demonstrated marked geographic expansion in recent years. A.

Ecological dynamics of blacklegged ticks, vertebrate hosts, and associated zoonotic pathogens in northeastern forests

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Specific host‐tick interactions in temperate forest systems influence variation in density and infection prevalence of nymphal blacklegged tick (Ixodes scapularis). The density of infected nymphs (DIN), which is the product of nymphal infection prevalence (NIP) and density of questing nymphs (DON), influences the risk of human exposure to tick‐

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.

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.

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.

Rickettsia parkeri genetic diversity from three different hard tick species (family: Ixodidae)

Parasites & Vectors
Background Rickettsia parkeri sensu stricto, a causative agent of spotted fever rickettsiosis, is spread via the bite of infected ticks within the Amblyomma maculatum complex group. In the United States of America (USA), Am.

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,
