bacteriophages and pathogens

[stutjamalgeo at PICARD.COLSF.EDU]

  I am an undergraduate student doing my senior thesis experiment.  
My question is, for whoever is qualified to answer me:

 What research do you know of where bacteriophages are used against
specific pathogenic bacteria?   

                                Thank you sincerely for your time,
