Verification of infections in young sheep, goats, camels, and donkeys after inoculation with was unsuccessful. Rickettsiae could not be isolated from peripheral blood or other tissues of the domestic animals, although similar isolation in guinea pigs and was successful. Antibody response in sheep and goats varied with the size of the inoculum. Injection of similar quantities of live or dead into young sheep produced similar agglutinin and complement-fixing serum antibody responses. Thus, antibody response alone is not certain evidence of infection in domestic animals. Infection of the ticks , and by feeding on rickettsemic , guinea pigs, and gerbils was unsuccessful, although intracoelomic inoculation produced generalized infections in and but not in . Failure to produce rickettsemia in domestic animals and to infect ticks by feeding on rickettsemic suggests that neither domestic animals nor ticks are importantly involved in the epidemiological cycle of epidemic typhus.
