Detection of a Borrelia species in questing Gulf Coast ticks, Amblyomma maculatum. [PDF]

Ticks Tick Borne Dis, 2014
Borrelia spp. are agents of Lyme disease and relapsing fever, diseases which use Ixodes hard ticks and Ornithodoros soft ticks, respectively, as primary vectors. Some relapsing fever spirochetes, such as B. miyamotoi, are also found in hard ticks. To date, no Borrelia sp. is known to use the hard tick, Amblyomma maculatum, as a vector. However, both B.

Survey of Borreliae in ticks, canines, and white-tailed deer from Arkansas, U.S.A.

Parasites & Vectors, 2012
Background In the Eastern and Upper Midwestern regions of North America, Ixodes scapularis (L.) is the most abundant tick species encountered by humans and the primary vector of B. burgdorferi, whereas in the southeastern region Amblyomma americanum (Say)

Diversity and seasonality of host-seeking ticks in a periurban environment in the Central Midwest (USA).

PLoS ONE, 2021
Between March 2014 and February 2017, host-seeking ticks were collected during the late spring and summer months seasonally, and as well as continually through all seasons from several sites in a periurban environment in Pittsburg, Kansas, located in the

Rickettsia parkeri in Gulf Coast Ticks, Southeastern Virginia, USA

Emerging Infectious Diseases, 2011
We report evidence that Amblyomma maculatum tick populations are well established in southeastern Virginia. We found that 43.1% of the adult Gulf Coast ticks collected in the summer of 2010 carried Rickettsia parkeri, suggesting that persons living in or

Unusual paralytic response to Amblyomma maculatum nymphal bite in alpha-gal knockout mice

Frontiers in Arachnid Science
The Gulf-Coast tick (Amblyomma maculatum) is an emerging species whose geographic range is expanding in the United States. Although tick bite-induced paralysis is uncommon, Am. maculatum has been implicated in cases affecting vertebrate hosts.

Rickettsia parkeri and Rickettsia montanensis, Kentucky and Tennessee, USA

Emerging Infectious Diseases, 2014
We found that 14.3% (15/105) of Amblyomma maculatum and 3.3% (10/299) of Dermacentor variabilis ticks collected at 3 high-use military training sites in west-central Kentucky and northern Tennessee, USA, were infected with Rickettsia parkeri and ...

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.

Discovery of Alpha-Gal-Containing Antigens in North American Tick Species Believed to Induce Red Meat Allergy

Frontiers in Immunology, 2019
Development of specific IgE antibodies to the oligosaccharide galactose-α-1, 3-galactose (α-gal) following tick bites has been shown to be the source of red meat allergy. In this study, we investigated the presence of α-gal in four tick species: the lone-

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

Olfactory responses of Amblyomma maculatum to rumen fluid and other odourants that attract blood-seeking arthropods

, 2022
Amblyomma maculatum Koch (Ixodida: Ixodidae) has emerged as a significant vector of human and companion animal diseases in the U.S.A. When expanding in range, A. maculatum can be difficult to collect in the field and control on livestock.
