title: [Differential traits and antigenic properties of the S- and R-forms of Neisseria meningitidis].
abstract: The authors demonstrated a marked dissociation of the Neisseria meningitis cultures and the capacity to their rapid change from S- to R-forms. Differential signs of the S- and R-forms are described. Differences in the degree of dissociation of the cultures depending on their origin were shown: strains isolated from the cerebrospinal fluid and the blood of patients with meningitis proved to be less dissociated, and those isolated from carriers--more dissociated. Transfers from media to media and adaptation of cultures to artificial nutrient media produced the greatest influence on dissociation of the freshly isolated strains.
