Isolation of Heartland Virus from Lone Star Ticks, Georgia, USA, 2019

Emerging Infectious Diseases, 2022
Report of a human death and exposure of white-tailed deer to Heartland virus (HRTV) in Georgia, USA, prompted the sampling of questing ticks during 2018–2019 in 26 sites near where seropositive deer were captured and the residence of the human case ...

Ultrastructure of Haller's organ in the tick Amblyomma americanum (L.) [PDF]

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972
Haller's organ on the tarsus of the tick Amblyomma americanum (L.) (Acarina: Ixodidae; nymphal stage) was studied by scanning and transmission electron microscopy. It consists of a distal bristle group, (the “anterior pit”), and a proximal “capsule” which encloses several sensilla. The seven sensilla of the anterior pit (A1–A7) are all thick-walled and

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.

Mosquito and tick repellency of two Anthemis essential oils from Saudi Arabia

Saudi Pharmaceutical Journal, 2018
The essential oils (EOs) of Anthemis melampodina (Am) and Anthemis scrobicularis (As) (Asteraceae) were extracted from the aerial parts of the plants by hydrodistillation, and their chemical compositions were analyzed using GC-FID and GC-MS.

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 ...

Borreliacidal activity of saliva of the tick Amblyomma americanum [PDF]

Medical and Veterinary Entomology, 2005
Abstract.  Amblyomma americanum (Linneaus) (Acari: Ixodidae), an important tick vector of human and animal disease, is not a competent vector of the bacterial agent of Lyme disease, Borrelia burgdorferi , although its range overlaps the geographical ...

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.
