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‐

Novel Borrelia burgdorferi isolates from Ixodes scapularis and Ixodes dentatus ticks feeding on humans [PDF]

Journal of Clinical Microbiology, 1996
Seven cultures of Borrelia burgdorferi differing from strains B31 and ZS7 were identified from among 99 isolates from Ixodes scapularis ticks and from white-footed mice (Peromyscus leucopus) and 1 isolate from an Ixodes dentatus tick. Five of the six novel isolates from I. scapularis and the isolate from I.

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.

Human Babesia microti Incidence and Ixodes scapularis Distribution, Rhode Island, 1998–2004

Emerging Infectious Diseases, 2007
Distribution of nymphal Ixodes scapularis in Rhode Island was used as a logistical regressor for predicting presence of human babesiosis. Although the incidence of babesiosis is increasing in southern Rhode Island, large areas of the state are free of ...

Harnessing 50 years of tick population genetics: Choosing the right molecular tool for contemporary research

Journal of Animal Ecology, Volume 94, Issue 11, Page 2159-2177, November 2025.
Population genetics reveals how ticks interact with hosts, microbiomes and environments. This review guides researchers in choosing the best tool for the job, weighing cost, resolution, reproducibility and throughput to study tick population structure. Abstract Ticks are ectoparasites of major medical, veterinary and ecological importance, transmitting

Exploring the sialome of the tick Ixodes scapularis

Journal of Experimental Biology, 2002
SUMMARY To attempt description of the set of mRNA and protein (sialome) expressed in the salivary glands of the tick Ixodes scapularis, we randomly sequenced 735 clones of a full-length salivary gland cDNA library of this arthropod and performed Edman degradation of protein bands from salivary gland homogenates (SGH) and saliva separated

Seroprevalence of Borrelia burgdorferi, B. miyamotoi, and Powassan Virus in Residents Bitten by Ixodes Ticks, Maine, USA

Emerging Infectious Diseases, 2019
We conducted a serosurvey of 230 persons in Maine, USA, who had been bitten by Ixodes scapularis or I. cookei ticks. We documented seropositivity for Borrelia burgdorferi (13.9%) and B.

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.

Tick phenology, tick-host associations, and tick-borne pathogen surveillance in a recreational forest of East Texas, USA.

PLoS ONE
Management of tick-borne disease necessitates an understanding of tick phenology, tick-host associations, and pathogen dynamics. In a recreational hotspot outside of one of the largest cities in the United States, we conducted a year of monthly ...
