Abstract

The present invention relates to the treatment of bacterial infections and the reduction of inflammatory response using bacteriophage compositions. In an aspect, provided herein are methods of treating a bacterial infection characterized by inflammation in a subject, the method comprising administering to the subject a bacteriophage composition that is essentially free of impurities, wherein the composition reduces inflammation

         13 . The composition or method of any one of the preceding claims, wherein the bacteriophage of the composition infect and lyse  Staphylococcus.    
     
     
         14 . The composition or method of any one of the preceding claims, wherein the bacteriophage of the composition infect and lyse  Staphylococcus aureus.    
     
     
         15 . The composition or method of any one of the preceding claims, wherein the bacteriophage of the composition infect and lyse methicillin-resistant  Staphylococcus aureus.    
     
     
         16 . The method of  claim 1  wherein the bacterial infection is selected from chronic rhinosinusitis, sinus infection, lung infection, urinary tract infection and intra-abdominal infection. 
     
     
         17 . The method of  claim 14  wherein the bacteriophage composition comprises two or more strictly lytic bacteriophage from the Myoviridae family and two or more strictly lytic bacteriophage from the Podoviridae family. 
     
     
         18 . The method of  claim 14  wherein the bacteriophage composition comprises one or more bacteriophages selected from: Pa223, Pa222, Pa193, and Pa204 and mutants thereof. 
     
     
         19 . The method of  claim 14  wherein the bacteriophage composition comprises at least two bacteriophages selected from: Pa223, Pa222, Pa193, and Pa204 and mutants thereof. 
     
     
         20 . The method of  claim 14  wherein the bacteriophage composition comprises at least three bacteriophages selected from: Pa223, Pa222, Pa193, and Pa204 and mutants thereof.
