Bacteriophages are viruses that infect and parasitize bacteria. The current increase in the incidence of antibiotic resistance in human bacteria has favored the study of phages as a therapeutic alternative (phage therapy). Phage therapy is defined as the administration of virulent phages directly to a patient to lyse the bacterial pathogen that is causing a clinically severe infection. The ideal route of administration and modification of bacteriopaghes genetically to deactivate bacterial resistance genes is the next future to antibiotic recovery sensitivity of MDR organisms.
