title: [Interferon induced in the hamster by subunits of "Nocardia": essay of protection against rabies (author's transl)].
abstract: Lipid-free cells of Nocardia opaca and a cell extract (NWSM) are interferon inducers in syrian hamsters: peak interferon appears 2 h after injection as compared to 8 h in the case of interferon induced by inactivated NDV virus. The interferon induced by Nocardia product is inactivated by a treatment for 30 min at 56 degrees C or 24 h at pH 2: NDV-induced interferon is more stable under these conditions. Hamsters inoculated with NWSM before and after infection with rabies virus are partially protected: their survival time is slightly increased.
