Carryover Effects of Thermal Conditions on Tick Survival, Behavior, and Simulated Detectability. [PDF]

open access: yesEcol Evol
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.

Diversity of rickettsiae in ticks (Acari: Ixodidae) collected from wild vertebrates in part of the Amazon, Cerrado, and Pantanal biomes in Brazil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2023
Ticks parasitizing 102 wild animals in the states of Mato Grosso and Goiás, Brazil were collected between 2015 and 2018. A total of 2338 ticks (865 males, 541 females, 823 nymphs, and 109 larvae) belonging to four genera (Amblyomma, Dermacentor ...

The bacterial community of the lone star tick (Amblyomma americanum)

open access: yesParasites & Vectors, 2021
Background The lone star tick ( Amblyomma americanum ), an important vector of a wide range of human and animal pathogens, is very common throughout the East and Midwest of the USA. Ticks are known to carry non-pathogenic bacteria that may play a role in

A Case of Illness Following a Bite by a Male Lone Star Tick (<i>Amblyomma americanum</i> Linnaeus) Infected With <i>Ehrlichia</i> sp. and <i>Rickettsia amblyommatis</i> in Connecticut, United States. [PDF]

open access: yesClin Case Rep
A case of local lymphadenopathy and a flu‐like illness in a man, following a bite by a male lone star tick infected with Ehrlichia sp. and Rickettsia amblyommatis. ABSTRACT The lone star tick (Amblyomma americanum Linnaeus) is a species commonly found in the southeastern U.S., but in recent years its populations have expanded northward, resulting in an

Predicting the Potential Global Distribution of Amblyomma americanum (Acari: Ixodidae) under Near Current and Future Climatic Conditions, Using the Maximum Entropy Model

open access: yesBiology, 2021
Simple Summary Amblyomma americanum (the lone star tick) is a pathogen vector that bites humans. It can cause severe disease in humans and animals, and may spread as the climate changes.

Lone Star Ticks (Amblyomma americanum):

open access: yesDelaware journal of public health, 2021
Public health messaging in the eastern United States has historically underemphasized the risks posed by lone star ticks (Amblyomma americanum), focusing instead on blacklegged ticks (Ixodes scapularis).

Automated identification of spotted-fever tick vectors using convolutional neural networks. [PDF]

open access: yesMed Vet Entomol
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.

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

open access: yes, 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.
