ABSTRACT:
The invention relates to DNA fragments encoding an Abi-type mechanism of resistance to bacteriophages, which fragments are capable of being obtained by cloning of chromosomal or plasmid DNA of a bacteriophage-resistant lactic acid bacterial strain, as well as to a polypeptide involved in an Abi-type resistance mechanism, encoded by one of the said fragments. The invention also encompasses recombinant vectors and transformed bacterial strains comprising the said DNA fragments.
