The work shows that killed autoclaved cultures of Listeria monocytogenes, resistant to 75,000 Unitsml of streptomycin, used in the capacity of a donor, transforms streptomycin resistance in the Staphylococcus pyogenes aureus recipient, analogous to the transforming action of the Salmonella typhimurium culture resistant to 75,000 Unitsml and killed at 75C. The rise of streptomycin resistance to staphylococcus cultivated in the autoclaved Listeria culture ran a parallel course with the rise of the resistance of staphylococci reared in a heated salmonella culture. The fact of transmission of streptomycin resistance to staphylococcus by microorganisms of two different genera points to the thermostability and similarity of factors of streptomycin resistance for staphylococci, listeria and salmonella.
