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.
Claims18
An isolated and purified DNA encoding a polypeptide having a sequence selected from the group consisting of SEQ ID NOS:
- 7, 12, 14 and 15.
An isolated DNA of more than 20 bp, comprising a fragment of SEQ ID NOS:
- 1, 11 or 13, wherein said isolated DNA hybridizes to a sequence complementary to said fragment.
An isolated DNA of more than 20 bp, comprising a fragment complementary to a sequence selected from the group consisting of SEQ ID NOS:
- 1, 11, and 13, wherein said isolated DNA hybridizes to said sequence.
