Phages, formally known as bacteriophages, are viruses that solely kill and selectively target bacteria. They are the most common biological entities in nature, and have been shown to effectively fight and destroy multi-drug resistant bacteria. Namely, when all antibiotics fail, phages still succeed in killing the bacteria and may save a life from an infection. phage has many potential applications in human medicine as well as dentistry, veterinary science, and agriculture.For more information, please contact the following e-mail address: Email: global@qyresearch . com Website: https://www . qyresearch . com
