Natural history of Amblyomma maculatum in Virginia. [PDF]
Ticks Tick Borne Dis, 2018 The Gulf Coast tick Amblyomma maculatum Koch is increasingly relevant to medical and veterinary communities as human infection rates of Rickettsia parkeri rise, the risk of introduction of Ehrlichia ruminantium increases, and the range of this tick expands into the densely populated Mid-Atlantic region of the United States.

Tick microbial communities within enriched extracts of Amblyomma maculatum. [PDF]
Ticks Tick Borne Dis, 2018 Our objective of this study was to explore the bacterial microbiome in fresh or fresh-frozen adult Amblyomma maculatum (Gulf Coast ticks) using extracts enriched for microbial DNA. We collected 100 questing adult A. maculatum, surface disinfected them, and extracted DNA from individual ticks collected the same day or after storage at -80 °C.

Comparative vertical transmission of Rickettsia by Dermacentor variabilis and Amblyomma maculatum. [PDF]
Ticks Tick Borne Dis, 2017 The geographical overlap of multiple Rickettsia and tick species coincides with the molecular detection of a variety of rickettsial agents in what may be novel tick hosts. However, little is known concerning transmissibility of rickettsial species by various tick hosts.

Role of Sca2 and RickA in the Dissemination of Rickettsia parkeri in Amblyomma maculatum. [PDF]
Infect Immun, 2018 ABSTRACT The Gram-negative obligate intracellular bacterium Rickettsia parkeri is an emerging tick-borne human pathogen. Recently, R. parkeri Sca2 and RickA have been implicated in adherence and actin-based motility in vertebrate host cell infection models; however, the rickettsia ...

Rickettsia parkeri colonization in Amblyomma maculatum: the role of superoxide dismutases. [PDF]
Parasit Vectors, 2016 The Gulf Coast tick (Amblyomma maculatum) is an arthropod vector of Rickettsia parkeri, the causative agent of American boutonneuse fever and an infectious agent of public health significance. In this study, we evaluated the biological significance of the superoxide dismutases (SODs) of A. maculatum in hematophagy and R. parkeri colonization within the

Survey of Rickettsia parkeri and Amblyomma maculatum associated with small mammals in southeastern Virginia. [PDF]
Ticks Tick Borne Dis, 2020 Small mammals are often parasitized by the immature stages of hard-bodied ticks (family Ixodidae) and may serve as reservoir hosts of tick-borne pathogens. Amblyomma maculatum, the Gulf Coast tick, is the primary vector of Rickettsia parkeri, the causative agent of R. parkeri rickettsiosis.

Migratory Songbirds Transport Amblyomma longirostre and Amblyomma maculatum Ticks to Canada
Journal of Biomedical Research & Environmental Sciences, 2023 Birds transport ticks into Canada during northward spring migration, and some of these ticks are infected with tick-borne zoonotic pathogens. Some Amblyomma species harbour pathogens that cause debilitating diseases that can be fatal to humans, and domestic and wildlife animals. At least 65 Amblyomma spp.
