      • R. prowazekii multiplies in the gut epithelium of the louse which then detaches, ruptures, and releases rickettsiae into the feces. Rickettsiae from the infected feces enter the skin via abrasions or bite site and access the human host.

    Aug 8, 2023 · R. prowazekii multiplies in the gut epithelium of the body louse and explodes into the gastrointestinal (GI) tract, eventually killing the body louse in the process. In this regard, R. prowazekii is unique because no other known members of Rickettsia kill their vector.

    Aug 12, 2021 · R. prowazekii is transmitted from human to human via the body louse (Pediculus humanus), while all other so-far-known rickettsial species are transmitted to humans via ectoparasites from rodents, predominantly from rats and mice. Rodents serve as a natural reservoir and play a key role in the distribution of rickettsial infections.
