title: [Biological variants of a population of strains of the rabies street virus].
abstract: Experiments in mice weighing 6-7 g showed that a population of wild street rabies virus strains could contain from 1 to 3 biologic variants determining the clinical characteristics, duration of the incubation period and of the disease, and virus titres in the brain. Fox strains L-1 and L-2 produced only paralytic rabies, the BE strain isolated from a badger induced paralytic and chronic disease, and the population of the Yak strain isolated from a boy bitten by a fox and timely given a complete course of postexposure treatment contained 3 biologic variants: (1) VAR produced acute paralytic rabies throughout 59 passages, (2) VVR induced a disease of the type of "violent" rabies throughout 20 passages, and (3) VCR provoked chronic rabies in 27 passages.
