Abstract:
Summary.
Background. Against the backdrop of the growing problem of antibiotic resistance in the world, especially the variant of multidrug - resistance
(MDR), the attention of scientists is focused on finding alternative methods of combating bacterial infections. In recent years, increasing attention
has been paid to bacteriophages. The objectives of this review were to evaluate the possibilities and prospects for using bacteriophages in solving
modern problems of medical practice.
Materials and methods. The research is related to the analysis of bibliographic sources identified in PubMed, NCBI, EMBASE, Research Gate
Medline for the last few years.
Results. Bacteriophages are viruses that are specific bacterial pathogens that infect bacterial cells, actively multiplying in them and leading to their
lysis. The advantages and negative aspects of phage therapy are outlined, an overview of the successful use of mono- and combined preparations
of bacteriophages in medical practice, modern directions are described the use of bacteriophages not only for therapeutic, but also for preventive
purposes, based on the latest achievements of genetic engineering and biotechnology. The mechanism of interaction with a bacterial cell and
the life cycle of phages make it possible to use them for the treatment and prevention of bacterial infections, including combined ones. And thus
bacteriophages can be a promising alternative to antibiotic therapy. Unlike antibiotics, which kill pathogenic bacteria while also destroying normal
microbiota, causing a whole new set of problems, each phage has actually evolved to more specifically target specific bacterial strains or species.
This feature makes phage therapy an attractive alternative for fighting infections, especially those caused by multidrug-resistant bacteria such as
Pseudomonas aeruginosa, Streptococci spp., Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Proteus mirabilis and
others, which have strong adaptive mechanisms, are capable of forming biofilms, both on medical instruments and are a very effective protective
factor in vivo, etc. MDR has become a serious threat to human life and a significant burden for healthcare and the global economy. One of the
most important problems of modern public health is the problem of MDR associated with the provision of medical care. Bacteriophages have been
proposed as an alternative to antimicrobials for the treatment of MDR bacteria.
Conclusions. To address the increasing concern of antibiotic-resistant bacterial infections, it is imperative to promptly initiate a careful evaluation
and implementation of phage therapy as a sustainable treatment option. Despite the potential problems with widespread availability of phage
therapy, its implementation can bring social and economic benefits, significantly improving patient outcomes.
