Host-phage interactions and modeling for therapy.

Abstract

Phage are drivers of numerous ecological processes on the planet and have the potential to be developed into a therapy alternative to antibiotics. Phage at all points of their life cycle, from initiation of infection to their release, interact with their host in some manner. More importantly, to harness their antimicrobial potential it is vital to understand how phage interact with the eukaryotic environment in the context of applying phage for therapy. In this chapter, the various mechanisms of phage interplay with their hosts as part of their natural life cycle are discussed in depth for Gram-positive and negative bacteria. Further, the literature surrounding the various models utilized to develop phage as a therapeutic are examined, and how these models may improve our understanding of phage-host interactions and current progress in utilizing phage for therapy in the clinical environment.
