Western scientists have steadily been gaining interest in phage therapy since the mid-1980?s due to the rising problem of antibiotic resistance. Its introduction in the 20th century by Felix d?Herelle marked the beginning for the uses of bacteriophages as antibacterial agents. However, a lack in understanding phage biology, as well as the arrival of broad-spectrum antibiotics deprioritized using phage therapy to treat bacterial infections in the West. With the advent of molecular biology, we are now better able to understand the predator-prey relationships with which phage co-evolve with their hosts as well as the specificity of phage-host interactions which could lend itself into personalized treatments for infection. These discoveries give us greater insights on how to most effectively use bacteriophage as potential therapeutic agents. It is encouraging to note that bacteriophages are used as food additives in the U.S., suggesting that the FDA acknowledges the positive potential of bacteriophages for human applications. Unfortunately, there are only a few examples to date of bacteriophages used on humans in controlled clinical trials. Rigorous studies in-vitro and especially in-vivo are critically important to avoid the mishaps of our predecessors. Phage biologists must strive to meet regulatory standards and to design thorough, rugged studies in order to establish a substantiated need for phage therapy in health care.
