Characterization of rickettsial infection dynamics within Dermacentor variabilis and Amblyomma maculatum
… To this end, Dermacentor variabilis and Amblyomma maculatum ticks were exposed to R. rickettsii, R. parkeri, R. montanensis, R. amblyommii or R. felis. Rickettsial exposure negatively impacted the fitness of A. maculatum, but not D. variabilis. Transovarial and transtadial transmission of …

Discovery and Molecular Characterization of Selenoprotein M in the Salivary Glands of <i>Amblyomma maculatum</i>, the Gulf Coast Tick
… among the pathogens transmitted by <em>A. maculatum</em> to humans. Heavy infestations of <em>A. maculatum</em> on animal ears cause them to become thickened and curled, a condition commonly called "gotch ear." The tick's multifunctional salivary glands are vital to their biological success …

An Insight Into the Microbial Diversity and Expression of Cysteine Protease Inhibitors (Cystatin) in <i>Rickettsia parkeri</i> Infected <i>Amblyomma maculatum</i>
<p><em>Amblyomma maculatum</em> (Gulf Coast tick) is an emerging tick species of public health significance in United States. It is a competent vector of <em>Rickettsia parkeri</em>, an etiological agent of a human rickettsiosis. In this study, we investigated the spotted fever group of rickettsial …

Determining the Prevalence and Distribution of Tick-Borne Pathogens in Southeastern Virginia and Exploring the Transmission Dynamics of Rickettsia Parkeri in Amblyomma Maculatum
… of Rickettsia parkeri within its vector, Amblyomma maculatum. Although some rickettsiae are transovarially transmitted in ticks, little is known about the frequency and efficiency of this transmission route, and nothing is known regarding the transmission strategy of R. parkeri in A. …

Abiotic Factors Contributing to the Survival of Three Tick Species in Southeastern Virginia, <i>Amblyomma Americanum</i> (Lone Star Tick), <i>Dermacentor Variabilis</i> (American Dog Tick), and <i>Amblyomma Maculatum</i> (Gulf Coast Tick)
<p><em>Amblyomma americanum</em>, <em>Amblyomma maculatum</em>, and <em>Dermacentor variabilis</em> are hard-bodied ticks in the Hampton Roads area of southeastern Virginia. This study consisted of two field projects focused on these tick species. To estimate the off-host survival of local tick …

Ecology and Climate Tolerance of Emerging Tick Disease Vectors in Central Appalachia/Southwestern Virginia
… invasive, including Haemaphysalis longicornis, Amblyomma americanum, and Amblyomma maculatum, were examined through a combination of laboratory and field experiments. Amblyomma americanum and H. longicornis nymphal ticks had a lower supercooling temperature than adult ticks, suggesting their …

SURVEY OF Rickettsia spp. IN TICKS IN NACOGDOCHES COUNTY, TEXAS
… commonly transmitted by the Gulf Coast tick, <em>Amblyomma maculatum</em>. <em>Rickettsia parkeri</em> is the causative agent of <em>Rickettsia parkeri </em>rickettsiosis, which is a disease characterized by nonspecific symptomology. Significant effort by numerous research groups focuses on …

Mounting Sex Pheromone: A Novel Pheromone Responsible for Mate Recognition in the Ixodidae
… surface of <em>D</em>. <em>andersoni</em>, <em>Amblyomma maculatum</em> and <em>A. americanum</em>. This contact sex pheromone enables males excited and attracted by 2,6-dichlorophenol to identify the female as a potential mating partner. The MSP is the second in the series of three sex …
