[Isolation of a cytolytic strain of hog cholera virus from IB-RS2 cells (author's transl)].

An infectious agent, able to induce a definite cytopathic effect in pig kidney cell monolayers, was isolated from the IB-RS2 cell line. Immunofluorescence, seroneutralization and ultracentrifugation studies have permitted to identify this agent as hog cholera virus (HCV). Representative HCV-strains being devoid of pathogenicity in tissue culture, the practical and theoretical interest of such an isolation is discussed.
