Clinical, epidemiological, and laboratory features of Rickettsia parkeri rickettsiosis: A systematic review

Ticks and Tick-borne Diseases, 2021
Rickettsia parkeri rickettsiosis is recognized as the second most prevalent tick-borne disease caused by spotted fever group rickettsiae in the Americas, where two pathogenic strains (R. parkeri sensu stricto and R. parkeri strain Atlantic rainforest) have been related to human infections and transmitted by Amblyomma spp. ticks.

Rickettsia parkeri (Rickettsiales: Rickettsiaceae) in the Sky Islands of West Texas [PDF]

Journal of Medical Entomology, 2020
Abstract Rickettsia parkeri, a tick-borne pathogen distributed throughout several countries of the Americas, causes a mild to moderately severe, eschar-associated spotted fever rickettsiosis. Although most U.S. cases of R. parkeri rickettsiosis are reported from southeastern states, some have been reported recently from remote regions of

Experimental Infection of the Opossum Didelphis aurita by Rickettsia felis, Rickettsia bellii , and Rickettsia parkeri and Evaluation of the Transmission of the Infection to Ticks Amblyomma cajennense and Amblyomma dubitatum

Vector-Borne and Zoonotic Diseases, 2010
This work evaluated the infection of opossums (Didelphis aurita) by Rickettsia felis, Rickettsia bellii, and Rickettsia parkeri and their role as amplifier hosts for horizontal transmission to Amblyomma cajennense and/or Amblyomma dubitatum ticks ...

Cattle and the Natural History of Rickettsia parkeri in Mississippi

Vector-Borne and Zoonotic Diseases, 2011
Cattle have been recognized as hosts for Amblyomma maculatum, the Gulf Coast tick, for over 100 years. For nearly as long, A. maculatum have been known to harbor the spotted fever group Rickettsia (SFGR), now known as Rickettsia parkeri. However, human infection with R. parkeri was not documented until 2004.

Artificial Infection of the Bed Bug WithRickettsia parkeri

Journal of Medical Entomology, 2012
Although a variety of disease agents have been reported from bed bugs, the mechanical and biological disease transmission potential of bed bugs remains unelucidated. In this study we assayed survivability of the mildly pathogenic spotted fever group rickettsia, Rickettsia parkeri, in bed bugs after feeding on R. parkeri-infected chicken blood.

Rickettsia parkeri infections diagnosed by eschar biopsy, Virginia, USA

Infection, 2018
Infection with Rickettsia parkeri is an emerging tick-borne illness, often accompanied by fever and an eschar at the site of tick attachment. We present three cases of R. parkeri in Virginia residents.Case 1 presented initially afebrile, failed to seroconvert to rickettsial antigens, and was diagnosed by DNA testing of the eschar.

Detection of Amblyomma maculatum and Rickettsia parkeri in prairies of Central Missouri

Veterinary Parasitology: Regional Studies and Reports
The destruction and decline of prairie habitats due to landscape repurposing have profoundly impacted the diversity of plant, animal, and insect life. In the Central United States, the reconstruction of prairie habitats from farmland is a widely applied strategy to raise diversity and recreate a healthy, complex ecosystem.
