SURVEY OF Rickettsia spp. IN TICKS IN NACOGDOCHES COUNTY, TEXAS
<p><em>Rickettsia parkeri </em>is an obligate intracellular pathogenic bacterium that is 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 …

An Insight Into the Microbial Diversity and Expression of Cysteine Protease Inhibitors (Cystatin) in <i>Rickettsia parkeri</i> Infected <i>Amblyomma maculatum</i>
… 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 diversity in <em>A. maculatum</em> based on rickettsial <em>ompA</em> gene PCR. Our results showed <em>A. …

Identification and characterization of rickettsial proteins at the host-pathogen interface
… disease for numerous pathogens. Members of the Rickettsia genus are obligate intracellular bacteria that pose a growing threat to human health, but their complete dependence on the host cell niche has precluded a thorough investigation of the bacterial factors acting at the host-pathogen …

An obligate intracellular bacterial pathogen forms extensive and stable interkingdom contacts with the endoplasmic reticulum
… and advancing their life cycle. To this end, Rickettsia parkeri directly engages the host plasma membrane to infiltrate target cells and spread to neighboring ones. However, whether this pathogen directly engages other cellular membranes during infection remains unclear. Interestingly, a …

Discovery and Molecular Characterization of Selenoprotein M in the Salivary Glands of <i>Amblyomma maculatum</i>, the Gulf Coast Tick
… pathogens to humans and animals. <em>Rickettsia parkeri</em> is notable 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 …

Identification and Characterization of a Relish-type NF-kB, DvRelish in Dermacentor variabilis, the American Dog Tick
… and non-pathogenic Spotted fever group (SFG) Rickettsia are maintained and transmitted by ticks with specific hard tick-Rickettsia pairings evident in nature. The pathogenic SFG Rickettsia rickettsii is transmitted by the hard tick Dermacentor variabilis. In response to infection, D. …
