Abstract
This review talks about the importance of bacteriophages in animal health, highlighting their role as natural predators for bacteria. Bacteriophages, or phage, are viruses that particularly infected the bacterial cells, and provide a promising alternative way instead using traditional antibiotics for treatment bacterial infections, especially now, during the growing antibiotic resistance crisis. The review discuss molecular biology in the stages of bacteriophages, including their life cycle and transition mechanisms, which include both lytic and lysogenic pathways. Medical applications of phase therapy are investigated in the treatment infections of bacteria in livestock and pets, which emphasizes the ability of toned treatments against multi-resistant pathogens. In addition, Bacteriophage use in food security is addressed, their role in controlling food-borne pathogens without compromising favorable microbes. Overall, this review emphasizes the versatile applications of bacteriophages to increase animal health and food safety, and advocate further research and development in this promising region.
