Harnessing the Activity of Lytic Bacteriophages to Foster the Sustainable Development Goals and the "One Health" Strategy.

As bacteriophages (phages) are viruses that infect and destroy bacterial cells, they can be considered natural bactericides that can either directly or indirectly contribute to the achievement of the United Nations Sustainable Development Goals (UN SDGs) on health and well-being, food production and food security, as well as environmental protection and climate change mitigation, thus contributing to the success of the European "One Health" strategy to combat antimicrobial resistance in humans, animals, plants, and the environment. The biological activity of lytic bacteriophages can operate in the fields of microbiology and biotechnology for clinical, veterinary, agricultural, and industrial applications, among others, to achieve the proposed goals, mainly because the phages can help increase crop productivity by reducing bacterial diseases; constitute alternative therapies against infections caused by multidrug-resistant bacteria; can reduce populations of pathogenic bacteria that contaminate soil and water, therefore ensuring healthier and safer food production; and they can help reduce environmental pollution caused by the presence of agrochemicals and antibiotics. Phage-based therapies developed through research and innovation have the potential to promote greater global food security and health in a more environmentally friendly and eco-sustainable way.
