Bacteriophage Treatment: Critical Evaluation of Its Application on World Health Organization Priority Pathogens
Raghad Khalid AL-Ishaq | Sini Skariah | Dietrich Büsselberg
Bacteriophages represent an effective, natural, and safe strategy against bacterial infections. Multiple studies have assessed phage therapy’s efficacy and safety as an alternative approach to combat the emergence of multi drug-resistant pathogens. This systematic review critically evaluates and summarizes published articles on phages as a treatment option for <i>Staphylococcus aureus</i>, <i>Klebsiella pneumoniae</i>, <i>Pseudomonas aeruginosa</i>, and <i>Enterococcus faecalis</i> infection models. It also illustrates appropriate phage selection criteria, as well as recommendations for successful therapy. Published studies included in this review were identified through EMBASE, PubMed, and Web of Science databases and were published in the years between 2010 to 2020. Among 1082 identified articles, 29 studies were selected using specific inclusion and exclusion criteria and evaluated. Most studies (93.1%) showed high efficacy and safety for the tested phages, and a few studies also examined the effect of phage therapy combined with antibiotics (17.2%) and resistance development (27.6%). Further clinical studies, phage host identification, and regulatory processes are required to evaluate phage therapy’s safety and efficacy and advance their clinical use.
