Pathobiology of ESKAPE Biofilms in implant infections: current understanding and implications for future therapeutic strategies
Abstract
In the modern era, the expanding demand for implants has transformed the healthcare system by restoring and enhancing the function of various biological structures, thereby increasing the patients' quality of life. These include urinary catheters, dental, orthopedic, cardiovascular implants, and sutures designed to perform various functions. However, these devices are more prone to microbial attack, contributing to biofilm formation mainly caused by multidrug-resistant ESKAPE pathogens, thereby increasing the risk of implant-associated infections and implant failure. This review summarizes the diverse array of implants available on the market and their associated infections caused by biofilm-producing pathogens, with a particular emphasis on the ESKAPE pathogen. Specific keywords were used to conduct a literature review using Google Scholar, Web of Science, PubMed, and Scopus databases. The data were then screened and integrated to explore the underlying principles of biofilm formation, its consequences, diagnostic approaches, and therapeutic studies. Currently, various methods are employed to diagnose these infections, including culture-based methods (tissue swab, culture, sonication) and non-culture methods (Dithiothreitol, XTT (2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide), Resazurin, BioTimer assays, and PCR). However, these studies indicate an increased difficulty in detecting infections caused by ESKAPE pathogens due to biofilm formation,…
