Phages, or bacteria-eating viruses, attack prokaryotic cells which comes in a wide variety of forms and dimensions, with the majority of them being less than 100 nm. In essence, the vast majority of phages discovered are double-stranded DNA viruses, whereas the small number of others was discovered to be RNA or single-stranded DNA viruses. These living things are widespread in many settings, especially in moist sources. In the days before antibiotics, it was known to use phages to treat bacterial illnesses. The effectiveness of phage usage in in-vitro and in-vivo based systems against certain bacterial agents of human, animal, or plant illnesses is being evaluated in a variety of research. The procedure serves as a safe, all-natural framework for preventing illnesses brought by bacteria that are dangerous and resistant to antibiotics [1].
Bacteriophages, or phages for short, are viruses that infect and replicate inside bacteria. They are the most abundant and diverse biological entities on earth, with an estimated 10^31 phages present in the biosphere. Their significance lies in their ability to play a critical role in controlling bacterial populations, influencing microbial evolution, and potentially serving as a therapeutic tool for combating antibiotic-resistant bacteria. Phages were first discovered in the early 20th century, and their importance in the field of microbiology was quickly realized [2]. They were shown to be responsible for controlling bacterial populations in natural environments such as soil, water, and the gut of animals. Phages have also been used in various industrial applications such as food processing, where they can be used to control the growth of harmful bacteria in food products. One of the most significant roles of phages is in the regulation of bacterial populations. They play a crucial role in maintaining the balance of microbial communities in natural environments. When bacterial populations grow out of control, phages infect and replicate inside the bacteria, ultimately leading to their lysis and death. This process, known as the lytic cycle, releases new phages into the environment, which can then infect and replicate inside other bacteria. The lytic cycle ensures that bacterial populations remain in check, preventing the overgrowth of any one particular species [3].
Phages can also influence microbial evolution through a process known as Horizontal Gene Transfer (HGT). HGT is the transfer of genetic material from one organism to another, and it can occur between bacteria of the same or different species. Phages are known to facilitate HGT by integrating their genetic material into the bacterial genome, and this integration can lead to the acquisition of new traits such as antibiotic resistance [4]. This process can have significant implications for human health, as antibiotic-resistant bacteria are a major public health concern. Another area of interest for phage research is in the development of phage therapy in which phages to treat bacterial infections, and it has gained renewed interest as a potential alternative to antibiotics, especially in the face of rising antibiotic resistance. Phage therapy has been used successfully to treat bacterial infections in humans and animals, and it has been shown to be effective against a wide range of bacterial pathogens. However, there are several challenges that need to be overcome before phage therapy can be widely adopted as a clinical treatment, including the identification and characterization of suitable phages, as well as the development of standardized protocols for their production and delivery [5].
Phages also have the potential to be used in other applications, such as the detection of bacterial pathogens. Phages can be engineered to recognize and bind specifically to certain bacterial strains, and this specificity can be used to detect the presence of these bacteria in clinical or environmental samples. This approach has been used to develop phage-based biosensors for the detection of foodborne pathogens such as Salmonella and Listeria. Despite the many potential applications of phages, there are also challenges associated with their use. One of the main challenges is the lack of knowledge and understanding of phage biology, which has limited their development and application. Another challenge is the potential for the development of phage-resistant bacteria, which can occur when bacteria evolve mechanisms to avoid phage infection. This resistance can occur through various mechanisms, including modification of cell surface receptors or the production of anti-phage proteins.
In conclusion, bacteriophages are of significant importance due to their role in controlling bacterial populations, influencing microbial evolution, and potential therapeutic applications such as phage therapy. As research into phages continues to advance, their potential to provide solutions to antibiotic resistance and other public health concerns will become increasingly apparent. However, the challenges associated with their use must also be addressed to fully realize their potential.
