V. Evaluation of Cross-Immunity against Type 1 Dengue Fever in Human Subjects Convalescent from Subclinical Natural Japanese Encephalitis Virus Infection and Vaccinated with 17D Strain Yellow Fever Vaccine
Guinea-pigs recovered from an infection with the SM strain of murine typhus showed a partial immunity against the Panamanian JD strain of Q fever as indicated by prolongation of the incubation period and shortening of the febrile period.
In reverse cross-immunity experiments, guinea-pigs immune to the JD strain of Q fever showed a variable febrile reaction and consistent suppression or modification of the testicular reaction on inoculation with murine typhus rickettsia.
Complement-fixation tests, employing immune guinea-pig serums and yolk sac antigens, showed no significant cross-reactions.
