Rickettsia peacockii is a species of gram negative Alphaproteobacteria of the spotted fever group, identified from Rocky Mountain wood ticks (Dermacentor andersoni).[1] Its type strain is SkalkahoT. The organism is passed transstadially and transovarially, and infections are localized in ovarial tissues.
