title: Serological cross-reaction and cross-protection in guinea pigs infected with Rickettsia rickettsii and Rickettsia montana.
abstract: Antisera produced in guinea pigs inoculated with Rickettsia rickettsii or Rickettsia montana were cross-reactive but sufficiently specific to identify the primary infecting agent. Guinea pigs immunized with R. montana were protected from fatal infection with R. rickettsii, although a few (25%) developed mild fever of short duration.
