Impact of nanosystems in Staphylococcus aureus biofilms treatment

FEMS Microbiol Rev. 2019 Nov 1;43(6):622-641. doi: 10.1093/femsre/fuz021.

Abstract

Staphylococcus aureus (S. aureus) is considered by the World Health Organization as a high priority pathogen for which new therapies are needed. This is particularly important for biofilm implant-associated infections once the only available treatment option implies a surgical procedure combined with antibiotic therapy. Consequently, these infections represent an economic burden for Healthcare Systems. A new strategy has emerged to tackle this problem: for small bugs, small particles. Here, we describe how nanotechnology-based systems have been studied to treat S. aureus biofilms. Their features, drawbacks and potentialities to impact the treatment of these infections are highlighted. Furthermore, we also outline biofilm models and assays required for preclinical validation of those nanosystems to smooth the process of clinical translation.

Keywords: antibacterial activity; biofilm eradication; drug delivery; nanomedicine; nanotechnology.
