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‐

Can the Gram-negative bacterium Escherichia coli colonize the gut of Lone Star Tick (Amblyomma americanum)? [PDF]

, 2018
Ticks are obligate blood feeding ectoparasites and vectors of several mammalian pathogens (Williams-Newkirk et al, 2014). In addition to pathogens they also carry a bacterial community with commensal and symbiotic relationships (Bonnet et al, 2017 ...

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 ...

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.

Neuronal in vitro impact of Amblyommaamericanumsalivary glands extracts [PDF]

, 2018
When a tick feeds off a host, the salivary glands of the tick excrete saliva to assist the tick in feeding (1). The reason saliva assists the tick in consuming its blood meal is due to its immunosuppressive, anti-inflammatory, and anti-coagulant ...

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.

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

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 ...
