''Bacteriophage Isolation''. Bacteriophage will be isolated from 10 clinical samples as previously described (REF). Briefly, isolated colonies will be selected and cultured in 5 mL TPY broth (trypticase, phytone, and yeast extract) and cultued for 24 hours at 37oC in 5% CO2. | :''Bacteriophage Isolation''.

:After culture, 1500 µL of broth will be transferred to Trypticase Soy Agar (TSA) plates in triplicate (500uL each). One plate will be used for harvesting bacteriophage, a second plate will be used for propagating bacteriophage, and a third plate used for storing cultures. The remaining culture (3500uL) will be centrifuged for 10min at 2500 RPM. The supernatant will be removed and filtered through a 0.22 µm syringe filter. The syringe filters removes all cellular debris resulting in a pure bacteriophage culture. Bacteriopahge cultures will then be added to a bacterial lawns using 10-fold titrations to determine titers. Positive titers will result in plaque formation. | :After culture, 1500 µL of broth will be transferred to Trypticase Soy Agar (TSA) plates in triplicate (500uL each).
