Biofilms are bacterial communities that pose a major threat causing chronic infections on both biotic and abiotic surfaces, including human tissue and medical device surfaces. The use of phages and phage-derived enzymes can combat bacteria in biofilm structures, but may not completely eradicate all bacterial cells. Combining phages and/or phage-derived products with other antimicrobial agents like antibiotics, nanoparticles, and antimicrobial peptides could be an effective approach to remove biofilms and treat associated infections.
Biofilms are bacterial communities that live in association with biotic or abiotic surfaces and enclosed in an extracellular polymeric substance. Their formation on both biotic and abiotic surfaces, including human tissue and medical device surfaces, pose a major threat causing chronic infections. In addition, current antibiotics and antiseptic agents have shown limited ability to completely remove biofilms. In this review, the authors provide an overview on the formation of bacterial biofilms and its characteristics, burden and evolution with phages. Moreover, the most recent possible use of phages and phage-derived enzymes to combat bacteria in biofilm structures is elucidated. From the emerging results, it can be concluded that despite successful use of phages and phage-derived products in destroying biofilms, they are mostly not adequate to eradicate all bacterial cells. Nevertheless, a combined therapy with the use of phages and/or phage-derived products with other antimicrobial agents including antibiotics, nanoparticles, and antimicrobial peptides may be effective approaches to remove biofilms from medical device surfaces and to treat their associated infections in humans.
