The mitochondrial genome of the lone star tick (Amblyomma americanum)

Ticks and Tick-borne Diseases, 2015
Amblyomma americanum is an abundant tick in the southeastern, midwestern, and northeastern United States. It is a vector of multiple diseases, but limited genomic resources are available for it. We sequenced the complete mitochondrial genome of a single female A. americanum collected in Georgia using the Illumina platform. The consensus sequence was 14,

Discovery of filarial nematode DNA in Amblyomma americanum in Northern Virginia [PDF]

Ticks and Tick-borne Diseases, 2016
Ticks collected in 2011 were screened for the presence of filarial nematode genetic material, and positive samples were sequenced for analysis. Monanema-like filarial nematode DNA was recently discovered in Amblyomma americanum in northern Virginia, marking the first time genetic material from this parasite has been discovered in ticks in the state ...

Anaplasma Phagocytophilum, a Zoonotic Vector‐Borne Bacterial Species in Rodents and Its Associated Tick Vector: Systematic Review

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.
A. phagocytophilum infections have been detected from various rodent hosts and the associated ticks from different sites throughout the globe. Ixodes ticks were the most frequent tick observed in the studies, followed by Dermacentor tick and Haemaphysalis tick species. Apodemus rodent species were frequently observed, followed by Microtus spp.

Potential mechanisms implied in tick infection by arboviruses and their transmission to vertebrate hosts

Integrative Zoology, Volume 20, Issue 2, Page 315-330, March 2025.
We summarize the recent progress in understanding defense mechanisms in specific tissues or sites that are encountered by arboviruses and discuss their possible roles in virus infection or transmission. Abstract Ticks can transmit many pathogens, including arboviruses, to their vertebrate hosts.

Relative Risk for Ehrlichiosis and Lyme Disease in an Area Where Vectors for Both Are Sympatric, New Jersey, USA

Emerging Infectious Diseases, 2017
The lone star tick, Amblyomma americanum, is a vector of Ehrlichia chaffeensis and E. ewingii, causal agents of human ehrlichiosis, and has demonstrated marked geographic expansion in recent years. A.

Liquid water intake of the lone star tick, Amblyomma americanum: Implications for tick survival and management

Scientific Reports, 2020
Ixodid ticks are ectoparasites that feed exclusively on blood as their source of nutrients. Although ticks spend most of their life off the host, until now it has been assumed that the blood and the water vapor are the only sources of water to maintain ...

Improving distribution models of sparsely documented disease vectors by incorporating information on related species via joint modeling

Ecography, Volume 2025, Issue 3, March 2025.
A necessary component of understanding vector‐borne disease risk is accurate characterization of the distributions of their vectors. Species distribution models have been successfully applied to data‐rich species but may produce inaccurate results for sparsely documented vectors. In light of global change, vectors that are currently not well‐documented

New Jersey-Wide Survey of Rickettsia (Proteobacteria: Rickettsiaceae) in Dermacentor variabilis and Amblyomma americanum (Acari: Ixodida: Ixodidae).

American Journal of Tropical Medicine and Hygiene, 2020
For the last decade, the New Jersey (NJ) Department of Health has reported between 42 and 144 new cases each year of "spotted fever group rickettsiosis" (SFGR), a statistic that reflects uncertainty regarding which rickettsial agents (Proteobacteria ...

Whole Genome Sequencing Reveals Clade‐Specific Genetic Variation in Blacklegged Ticks

Ecology and Evolution, Volume 15, Issue 2, February 2025.
In this study, we performed whole genome nanopore sequencing of individual blacklegged ticks across their geographical range to evaluate genetic divergence among populations. Our integrated analyses identified genetic variants associated with numerous biological processes and molecular functions that segregated across populations.
