A method and composition for the production of sequence specific antimicrobials capable of overcoming inefficient delivery, narrow host range, and potential transfer of virulence genes by generalized transduction of phage-based delivery systems by integrating CRISPR/Cas9 system in the phage genome, removing major virulence genes from host chromosome, and expanding host specificity of phage by complementing tail fiber protein which significantly improves the efficacy and safety of CRISPR/Cas9 antimicrobials as alternative therapeutics. The method and composition provide an efficacious and safe CRISPR/Cas9 antimicrobial, broadly applicable to MRSA. |
