Comparison of single bacteria and a bacterial reference community in a test against coated surfaces of varying copper content

Abstract

Introduction: Pathogens can easily transmit via surfaces and objects. In light of the ongoing pandemic of antimicrobial resistance, silently threatening millions worldwide, this is of particular concern in clinical and public environments. Thus, it is crucial to understand how antimicrobial materials influence surface-associated microbes and microbial communities. Copper, known for its antimicrobial activity, has demonstrated effectiveness against numerous clinically relevant pathogens. However, these in vitro pure cultures are in stark contrast to the in vivo microbial communities. Additionally, the application of pure copper surfaces is high in cost and maintenance.
