At this time, multidrug-resistant bacteria are seen as a danger to world health. This has rekindled interest in using bacteriophages to combat bacterial infections, together with the pharmaceutical industry's disinvestment in the development of novel-acting antibiotics and the urgent need for alternative therapies. This is brought on by phages' bacteriolytic abilities, which cause cell death. By releasing the freshly created phage particles from the infected cells to the environment, double-stranded DNA phages (ds DNA phages) put an end to a lytic cycle. They must produce lysis proteins that exert their action at the proper time in order to go past each barrier of the cell envelope in order to accomplish this. It is this ability of bacteria to lyse that is being investigated for usage. Entire phages or their derived proteins for therapeutic uses, biocontrol in the food industry, and the identification of dangerous bacteria [1].
