Identification of the Virus of Lymphocytic Choriomeningitis

Abstract
Nine strains of the virus of lympho-cytic choriomeningitis were identified by complement fixa-tion. The soluble antigen associated with the disease and responsible for fixation was detected in the spleens of infected guinea-pigs and mice. In addition, the development of anti-soluble substance antibodies was demonstrated in guinea pigs surviving infection with the agents. The significance which may be attached to the isolation of the virus from animals inoculated with human material is discussed.
