[Effect of bacterial preparations on the survival of irradiated animals]

A comparison of therapeutic effects of bacterial preparations (vaccinum dysenteriae, colibacterinum, bifidumbacterinum, bificolum) after gamma-irradiation was carried out. Bificolum showed the maximum and bifidumbacterinum the minimum effect, while colibacterianum had a therapeutic effect only within a narrow range of doses. Vaccinum dysenteriae was also effective.
