摘要

In order to ensure the holistic protection of human, animal and environmental health (commonly referred to as One Health), alternatives to the available antimicrobial approaches are required. Although antibiotic drugs have an outstanding broad spectrum of activity, their use is under discussion due to increasingly occurring resistances. Furthermore, the utilisation of antibiotics can result in significant consequences for the affected microbiome, often irreversibly altering its natural composition. The necessity for the implementation of alternative and targeted control measures for bacterial pathogens (e.g. zoonoses) represents a significant challenge for all sectors within the One Health framework. With growing interest, control strategies, some of which have been neglected for centuries, are under discussion for use as valuable tool for safeguarding health across all sectors.

Bacteriophages (phages) represent a naturally occurring biological resource with promising potential for use in targeted biocontrol of specific bacteria. As bacterial viruses, they interact specifically with their bacterial hosts, invading them to utilize the bacterial metabolism for their replication, finally destroying the infected bacterial cell. The benefits of this natural predator–prey relationship for the control of bacterial pathogens have long been recognized and extensively studied. This review summarises selected studies on the use of phages, illustrating the potential and application possibilities, but also the challenges of phage use. Due to their cross-sectoral relevance, the use of phages in farm animals, food and the environment is presented as an example.
