### Claim 2

The use of a bacteriophage strain selected from among strains deposited in the Polish Microbiological Collection under the accession numbers: PCM F/00046, PCM F/00047, PCM F/00048; PCM F/00049; PCM F/00050; PCM F/00051; PCM F/00052; PCM F/00053; PCM F/00054; PCM F/00055; PCM F/00056; PCM F/00057; PCM F/00058; PCM F/00059; PCM F/00060; PCM F/00061 or PCM F/00062 in the production of antibacterial preparations for use in combating bacteria belonging to the genus Stenotrophomonas.

### Claim 3 (depends on 2)

A use according to claim 2, characterised in that the counteracted bacteria belong to the species Stenotrophomonas maltophilia.
