Abstract
One of the critical issues that humans worldwide are facing is bacterial infections. Antibiotics
were developed as bactericidal agents to avoid the negative consequences of bacterial infections,
and they were initially highly efficient against bacteria. However, we face a phenomenon
called antibiotic resistance by misusing these chemical antibiotics in this era. In other words, bacteria
began to acquire resistance to common antibiotics, and resistance means going back to a time
before antibiotics. As it is a significant threat to human health and causes increased mortality, there
is a rising demand for novel alternative therapies. An alternate method is to use bacteriophages
(phages) as a therapeutic agent against bacterial infections in medicine and agriculture. Phages are
viruses capable of infecting pathogenic bacteria, which can cause serious diseases. They do not
affect the human microbiota; most only infect certain bacteria. Some research has been done on
using phages as a treatment, and more experiments today. For instance, eye infections caused by
methicillin-resistant Staphylococcus aureus (MRSA) can be treated by eye drops containing appropriate
phages. In this regard, significant progress has been made in phage therapy. This review will
discuss the current state of phage therapy, clinical breakthroughs, its superiorities and drawbacks,
and the future perspectives of phage applications.
Keywords:
Antibiotics, antibiotic resistance, agriculture, bacteriophage, phage therapy, plant pathogenic bacteria.
