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 ...

Infecção por riquétsias em carrapatos de aves silvestres em duas ecorregiões da Argentina [PDF]

, 2016
Several tick-borne Rickettsia species are recognized human pathogens in Argentina. Here we evaluated rickettsial infection in ticks collected on passerine birds during 2011-2012 in two eco-regions of Argentina.

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.

Ixodid ticks in the Western Ukraine

Scientific Messenger of LNU of Veterinary Medicine and Biotechnologies, 2020
During the 2018–2019 years, 2884 ticks were collected from five species of animals, including pets (dogs and cats), cattle (cows and horses) and wildlife (wild boar) in Khmelnytsky, Chernivtsi and Vinnytsia regions. Ixodid ticks were identified as: D. reticulatus (2370; 82.2 % of all collected ticks), I. ricinus 510 (17.7 %) and 4 of I. hexagonus (0.1 %

Stable isotope analysis of ectoparasites as a tool for understanding trophic interactions with mammalian hosts

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 664-674, December 2025.
Ectoparasites showed significant δ15N enrichment compared to their hosts, indicating trophic enrichment, but δ13C preservation varied. Lice, fleas and ticks preserve their hosts' isotopic fingerprints to varying degrees, with lice reflecting host dietary patterns most closely, likely due to their exclusive, host‐specific feeding behaviour. The presence

CYTOGENETIC DETECTION OF INFECTIOUS AGENTS IN IXODID TICKS

Фундаментальная и клиническая медицина, 2016
Aim: To test whether the cytogenetic techniques can be used for detection of infectious agents in ixodid ticks. Materials and Methods: Suspensions of ixodid ticks were tested for encephalitis virus (TBEV) and pathogenic Borrelia (PB ...

Longistatin, a plasminogen activator, is key to the availability of blood-meals for ixodid ticks. [PDF]

PLoS Pathogens, 2011
Ixodid ticks are notorious blood-sucking ectoparasites and are completely dependent on blood-meals from hosts. In addition to the direct severe effects on health and productivity, ixodid ticks transmit various deadly diseases to humans and animals ...

Insights into the development of Ixodes scapularis: a resource for research on a medically important tick species [PDF]

, 2017
Ticks (Acari: Ixodida) are arthropod ectoparasites dependent on a bloodmeal from a vertebrate host at each developmental stage for completion of their life cycle.

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
