Bacteriophages: A Revisited Strategy for the Treatment of Severe Bacterial Infections

Bacteriophages are viruses that infect and parasitize bacteria. The current increase in the incidence of antibiotic resistance in human bacteria has favoredthe 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.
