Estimating the distribution of Oryzomys palustris, a potential key host in expanding rickettsial tick‐borne disease risk

Ecosphere, 2023
Increasingly, geographic approaches to assessing the risk of tick‐borne diseases are being used to inform public health decision‐making and surveillance efforts.

Amblyomma maculatum Feeding Augments Rickettsia parkeri Infection in a Rhesus Macaque Model: A Pilot Study. [PDF]

PLoS ONE, 2015
Rickettsia parkeri is an emerging eschar-causing human pathogen in the spotted fever group of Rickettsia and is transmitted by the Gulf coast tick, Amblyomma maculatum.

Rickettsiae in Gulf Coast Ticks,Arkansas, USA

Emerging Infectious Diseases, 2010
To determine the cause of spotted fever cases in the southern United States, we screened Gulf Coast ticks (Amblyomma maculatum) collected in Arkansas for rickettsiae. Of the screened ticks, 30% had PCR amplicons consistent with Rickettsia parkeri or Candidatus Rickettsia amblyommii.

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

Ticks and Tick-borne Diseases, 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.

Rickettsia parkeri Rickettsiosis, Arizona, USA

Emerging Infectious Diseases, 2016
In the United States, all previously reported cases of Rickettsia parkeri rickettsiosis have been linked to transmission by the Gulf Coast tick (Amblyomma maculatum). Here we describe 1 confirmed and 1 probable case of R.

Prevalence of Borrelia burgdorferi sensu lato genetic markers in blood-sucking ticks in suburban park zones in Saint Petersburg

Инфекция и иммунитет, 2020
Tick-borne bacterial and viral infections are widespread in middle latitudes of the Northern hemisphere. Natural foci of such infections coincide with geographic areas inhabited by ixodid ticks.

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-

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.

Landscape Genetics of the Gulf Coast Tick, Amblyomma maculatum

, 2023
Connectivity among populations helps to maintain genetic diversity, population stability, and resilience. The Gulf Coast tick, Amblyomma maculatum, is a vector of the pathogen Rickettsia parkeri. Persistence of tick populations with high rates of R. parkeri infection poses health risks to humans and animals.

Tick bite-induced alpha-gal syndrome and immunologic responses in an alpha-gal deficient murine model

Frontiers in Immunology
IntroductionAlpha-Gal Syndrome (AGS) is a delayed allergic reaction due to specific IgE antibodies targeting galactose-α-1,3-galactose (α-gal), a carbohydrate found in red meat.
