Rickettsia parkeriin Gulf Coast Ticks, Southeastern Virginia, USA
Emerging Infectious Diseases, 2011 We report evidence that Amblyomma maculatum tick populations are well established in southeastern Virginia. We found that 43.1% of the adult Gulf Coast ticks collected in the summer of 2010 carried Rickettsia parkeri, suggesting that persons living in or visiting southeastern Virginia are at risk for infection with this pathogen.

Development and characterization of a murine model of Rickettsia parkeri rickettsiosis
, 2022 Rickettsia parkeri, a member of the spotted fever group of Rickettsia, is the agent of an emerging rickettsiosis in the southeastern United States and South America. Despite increased recognition of human cases, limited information is available regarding

Rickettsia parkeriInfection in Domestic Dogs, Southern Louisiana, USA, 2011
Emerging Infectious Diseases, 2012 The association between companion animals and tick-borne rickettsial disease has long been recognized and can be essential to the emergence of rickettsioses. We tested whole blood from dogs in temporary shelters by using PCR for rickettsial infections. Of 93 dogs, 12 (13%) were positive for Rickettsia parkeri, an emerging tick-borne rickettsiosis.

Emerging Infectious Diseases, 2006 To the Editor: During 1990 in Uruguay, a rickettsiosis in the spotted fever group was presumptively diagnosed for 3 patients who had fever, an initial small maculopapulous lesion at the site of a tick bite on the scalp, and subsequent regional lymphadenopathy.

Ecosphere, Volume 14, Issue 3, March 2023., 2023 Abstract Increasingly, geographic approaches to assessing the risk of tick‐borne diseases are being used to inform public health decision‐making and surveillance efforts. The distributions of key tick species of medical importance are often modeled as a function of environmental factors, using niche modeling approaches to capture habitat suitability ...

Current Protocols, Volume 2, Issue 11, November 2022., 2022 Abstract The guinea pig was the original animal model developed for investigating spotted fever rickettsiosis (SFR). This model system has persisted on account of the guinea pig's conduciveness to tick transmission of SFR agents and ability to recapitulate SFR in humans through clinical signs that include fever, unthriftiness, and in some cases the ...
