Abstract

The present invention relates to a novel bacteriophage ΦCJ27 (KCCM11465P) and a composition containing the same as an active ingredient. Further, the present invention relates to a method for preventing and/or treating infective diseases caused by enterotoxic Escherichia coli (ETEC) of non-human animals using the ΦCJ27 (KCCM11465P) and the composition.

First claim

The invention claimed is:

1. A feed composition comprising a feed and an additive comprising bacteriophage ΦCJ27 deposited as accession number KCCM11465P.

2. A drinking water composition comprising drinking water and an additive comprising bacteriophage ΦCJ27 deposited as accession number KCCM11465P.

3. A method for preventing or treating infectious diseases caused by Salmonella , comprising:
administering bacteriophage ΦCJ27 deposited as accession number KCCM11465P to a non-human animal.

4. The method for preventing or treating infectious diseases caused by Salmonella according to claim 3 , wherein the animal is poultry.

5. A method for preventing or treating infectious diseases caused by Salmonella , comprising:
administering a composition comprising bacteriophage ΦCJ27 deposited as accession number KCCM11465P to a non-human animal.

6. A method of preparing an additive composition, the method comprising:
providing bacteriophage ΦCJ27 deposited as accession number KCCM11465P; and
mixing the bacteriophage with at least one additional material to provide the additive composition.

7. The method of claim 6 , wherein the bacteriophage is in an amount of 0.05 wt % to 10 wt % based on the weight of the additive composition.

8. A method of preparing a feed composition, the method comprising:
preparing an additive composition according to the method of claim 6 ; and
mixing the additive composition with an animal feed to provide the feed composition.

9. A method of feeding, the method comprising:
preparing the feed composition according to the method of claim 8 ; and
providing the feed composition to an animal.

10. A method of preparing a drinking water composition, the method comprising:
preparing an additive composition according to the method of claim 6 ; and
mixing the additive composition with drinking water to provide the drinking water composition.

11. A method of providing drinking water to an animal, the method comprising:
preparing the drinking water composition according to the method of claim 10 ; and
providing the drinking water composition to an animal.
