Aerosol phage therapy for in vivo Burkholderia cepacia complex respiratory infections

  • In recent times, increased attention has been given to evaluating the efficacy of phage therapy, especially in scenarios where the bacterial infectious agent of interest is highly antibiotic resistant. In this regard, phage therapy is especially applicable to infections caused by the Burkholderia cepacia complex (BCC) since members of the BCC are antibiotic pan-resistant. Aerosol drug delivery is a common therapeutic delivery method for respiratory ailments and yet aerosol phage therapy has not previously been demonstrated to be effective for BCC infections. This study outlines the development of an in vivo model for evaluating aerosol delivery of phage therapeutics using a Nose-Only Inhalation Device (NOID). Immunocompromised mice infected with Burkholderia cenocepacia demonstrated a significant reduction in bacterial concentration when treated 24 h post-infection provided that the phage therapeutic was delivered at a sufficient concentration. This method shows promise for future evaluation of aerosolised respiratory phage therapeutics.
