ABSTRACT:
DNA fragment of phages which are virulent towards a Streptococcus, capable of conferring on a Streptococcus containing it resistance to at least one phage, especially a fragment homologous or hybridizing to the 3.6 kb HindIII fragment present in the plasmid CNCM I-1588 or the 6.5 kb EcoRV fragment present in the plasmid CNCM I-1589. Process for making a Streptococcus resistant to at least one phage, by cloning into a vector a DNA fragment of a phage which is virulent towards a Streptococcus, capable of conferring on a Streptococcus resistance to at least one phage and introducing the vector into a Streptococcus.
