An Overview of Antiviral Properties of Bacteriophages with Emphasis on the Treatment of COVID-19 Infection.

ABSTRACT

Bacteriophages or phages are the most abundant organisms in the biosphere. Scientists considered phages an appropriate tool for understanding molecular biology, horizontal gene transfer vectors, stimulants of bacterial evolution, a source of diagnostic and genetic tools, and new therapeutic agents. Therefore, studying the biology of phages and their interactions with their hosts is crucial to gaining a deeper knowledge of biological systems. Numerous studies confirmed that bacteriophages are a genetic tool with high potential for treating infectious diseases, including bacterial, fungal, and viral infections. Therefore, phages may be used as an appropriate therapeutic target against some viruses, such as COVID-19 infection. In this study, we describe the role of phages in modulating the host immune system, the production of specific antibodies against the COVID-19 virus by the host immune system, and the minimization of damage caused by the COVID-19 virus to the host. Also, the present study expresses our understanding of the prospect of phage therapy as an adjunctive therapy.
