title: Low-pathogenicity variant of lymphocytic choriomeningitis virus.
abstract: A noncytopathic virus has been isolated from a line of strain L mouse fibroblasts infected with lymphocytic choriomeningitis (LCM). This virus has low pathogenicity for mice and renders them immune to intracerebral challenge with virulent LCM virus.
