The over usage of antibiotics leads to antibiotic abuse which in turn eventually raises resistance mechanisms among wide range of pathogens. Due to lack of experimental data of efficacy of phages as potential antimicrobial and therapeutic agent and also more specific and cumbersome isolation process against specific pathogens makes it not so feasible technology to be looked as an alternative therapy. But, recent developments in genome editing techniques enables programmed nuclease enzymes that has effectively improvised our methodology to make accurate changes in the genomes of prokaryote as well as eukaryote cells. It is already strengthening our ability to improvise genetic engineering to disease identification by facilitating the creation of more precise models to identify the root cause. The present chapter discusses on improvisation of phage therapy using recent genome editing tools and also shares data on the methods of usage of phages and their derivatives like proteins and enzymes such as lysins and depolymerases, as a potential therapeutic or prophylaxis agent. Methods involved in recombinant based techniques were also discussed in this chapter. Combination of traditional approach with modern tools has led to a potential development of phage-based therapeutics in near future.
