Engineering nucleases to achieve targeted genome editing has turned out to be a revolutionary means for manipulating the genetic content in diversified living organisms. For targeted genome editing, till to date, only three engineered nucleases exist viz. zinc finger nucleases, transcription activator–like effector nucleases and RNA-mediated nucleases (RGNs) (Cas nucleases) from the clustered regularly interspaced short palindromic repeat (CRISPR). Among, Cas9 nuclease has been considered as a simplest tool for efficient modification of endogenous genes in an extensive stretch of organisms, owing to its amenability to design guide RNA compatible to the sequence of new targets. Moreover, CRISPR/Cas system delivers a multipurpose RNA-guided DNA-targeting platform called as CRISPR interference (CRISPRi), as well as epigenetic modifications and high throughput screening in diverse organism including bacteria, all in a sequence explicit way. With these entire advancements, the present chapter illustrates the deployment of CRISPR/Cas9 in bacterial genome editing and removal of pathogens.
