Abstract
Summary: Substrains of Pasteur fixed rabies virus are not identical in their antigenicity, incubation period, duration of symptoms, pathology, or in their ability to overcome rabies immunity in immunized mice. Ability to overcome immunity would seem to be a sensitive characteristic capable of differentiating viruses of rabies of the same ancestry but of differing biological evolution and may be shown by methods of testing other than the intracerebral cross immunity test.
