• Known allergy to phage products.
• Pregnant and/or breastfeeding.
• Immunocompromised at screening in the judgment of the investigator.
• Taking any systemic or topical antibacterial antibiotic within 2 weeks prior to the start of study treatment, for a condition other than Diabetic Foot Infection and DFO.
