Original title: Phage Therapy and Phage-Derived Lytic Proteins in the One Health Era: Mechanisms, Challenges and Emerging Innovations
Bacteriophages are viruses that infect bacteria, and some can kill them. Their lytic proteins, including endolysins, holins, and spanins, can also attack bacteria. But bacteria can resist phages, and these proteins cannot cross the outer membrane of Gram-negative bacteria. The review compares these approaches and describes possible ways to improve them, including engineered proteins and delivery systems.
Imagine trying to deliver a meal to a friend in a building with locked doors. You have to find the right entrance, and even then the delivery may be stopped or the friend may not be home. In this paper, the meal is a bacteria-killing treatment, the building’s doors are barriers such as bacterial outer membranes, and reaching the right friend stands for targeting the bacteria the treatment can affect.
Antibiotic-resistant infections threaten people, livestock, and aquaculture. This review examines viruses that infect bacteria and proteins made by those viruses as possible alternatives, alongside ways to address resistance and delivery challenges.
The abstract describes a review, not a specific clinical trial or direct comparison of treatment outcomes. It does not establish that phages or their proteins are effective or safe for every infection, nor that the proposed approaches solve the stated barriers. It also notes persistent constraints, including narrow host range, immune clearance, complex pharmacokinetics, and difficulty crossing Gram-negative outer membranes.
