Abstract

<i>Rickettsia parkeri</i>and<i>Candidatus</i>Rickettsia andeanae in Gulf Coast Ticks, Mississippi, USA

Highlights

We evaluated infection rates of R. parkeri and Candidatus Rickettsia andeanae, a recently identified but incompletely characterized spotted fever group Rickettsia (SFGR), in Gulf Coast ticks in Mississippi, USA
The overall prevalence of infection with SFGR species in Gulf Coast ticks sampled was 18.3%; 15.2% of ticks were singly infected with R. parkeri, and 1.7% were infected with R. parkeri and Candidatus R. andeanae
We found approximately 1 R. parkeriinfected Gulf Coast tick for every 6 ticks tested, suggesting that infected Gulf Coast ticks are commonly encountered in Mississippi
