Mechanisms of immunity in typhus infection: some characteristics of intradermal Rickettsia mooseri infection in normal and immune guinea pigs.

Rickettsia mooseri infection in skin at sites of intradermal inoculation was studied in nonimmune and immune guinea pigs with respect to dynamics of infection, localization of rickettsiae within tissues, and gross and microscopic pathology. Intradermal inoculation of R. mooseri into nonimmune guinea pigs resulted in gross lesions which, in magnitude, were… (More)
