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.
Claims10
DNA fragment of phages which are virulent towards a Streptococcus, capable of conferring on a Streptococcus containing it resistance to at least one phage, said fragment consisting of the 3.6 kb HindIII fragment present in the plasmid pMZ23. the 6.5 kb EcoRV fragment present in the plasmid pMZ31 or a fragment having the nucleotide sequence of SEQ ID NO:1.
DNA fragment of phages which are virulent towards a Streptococcus, said DNA fragment capable of conferring on a Streptococcus containing it resistance to at least one phage, wherein said DNA fragment hybridizes under stringent conditions to the 3.6 kb HindIII fragment present in the plasmid pMZ23, the 6.5 kb EcoRV fragment present in the plasmid pMZ31 or a fragment having the nucleotide sequence of SEQ ID NO:1.
