Abstract
The present invention relates to novel bacteriophages specific to Klebsiella pneumoniae strains, and compositions comprising the same. Particularly, polypeptides and their coding nucleic acid molecule of the novel bacteriophages are provided. The invention also relates to applications of the novel bacteriophages and the polypeptides in the detection/treatment/prevention of infection caused by Klebsiella pneumoniae strains. Development of immunogen and vaccine on the basis of the polypeptides are also provided.
Claims6
An isolated polypeptide having degradation activity specific to the capsule of Klebsiella pneumoniae capsular type K62 strains, selected from the group consisting of:
- (a) a polypeptide comprising the amino acid sequence of SEQ ID NO:
- 78;
- (b) a polypeptide which is encoded by a polynucleotide which hybridizes under at least high stringency conditions with (i) the polypeptide coding sequence of SEQ ID NO:
- 77, or (ii) a full-length complementary strand of (i);
- and (c) a polypeptide which is encoded by the polynucleotide sequence of SEQ ID NO:
- 77, wherein the isolated polypeptide comprises a peptide tag.
A vector containing an isolated polynucleotide, which comprises the nucleotide sequence of SEQ ID NO:
- 77 or a nucleotide sequence hybridizable under high stringency conditions to or complementary to the nucleotide sequence of SEQ ED NO:
- 77.
