Short Description of your Research or Creative Project (700 characters or less)

Rickettsia bacteria cause several human diseases. Ixodes pacificus, a common human biting tick, vectors Rickettsia species phylotype G022 (G022) and Rickettsia tillamookensis. Both species shares an evolutionary lineage with known rickettsial pathogens and have a low prevalence in I. pacificus. Recently the incidence of rickettsial diseases has increased, along with vector borne diseases (VBD). Between 2004-2016 a total of 491,671 cases of tick-borne diseases were reported in the United States (76% of all VBD). The pathogenicity of G022 and R. tillamookensis has never been documented. Here we report that G022 and R. tillamookensis have the capacity to be horizontally transmitted to mammals.
