Patent ID: 8685695

Claim:
A method for producing a mixture of bacteriophages comprising the steps of: a. growing a preculture of a methicillin-sensitive strain of Staphylococcus aureus species of bacteria; b. introducing at least two different separately reproduced strains of bacteriophage into the preculture of step (a), wherein said at least two different separately reproduced bacteriophage strains comprise at least two different serotypes of bacteriophage that specifically lyse bacteria of the species Staphylococcus; c. adding the preculture of step (b) to a main culture of a staphylococcus strain of bacteria at the time when the bacterial cells in the preculture begin to be lysed by bacteriophage to yield a combined culture of bacteria and bacteriophages; and d. purifying a mixture of bacteriophages from the combined culture of step (c), wherein the at least two different separately reproduced strains of bacteriophage set forth in step (b) and the mixture of bacteriophages set forth in step (d) comprise the bacteriophage MP13.3 having the accession number DSM 18722 and the bacteriophage KP3 having the accession number DSM 18723.
