Daptomycin-Loaded Nanocarriers Facilitate Synergistic Killing of Methicillin-Resistant Staphylococcus aureus via Lipid-Mediated Interactions and Targeting.

ABSTRACT: Preservation and augmentation of existing antimicrobials is crucial in combating antimicrobial resistance. Gram-positive bacteria, exemplified by Staphylococcus aureus, are among the most common human bacterial pathogens, with methicillin-resistant S. aureus (MRSA) now established globally. Daptomycin is a last-line anti-staphylococcal antimicrobial that uniquely targets the bacterial membrane with bactericidal effects. Here, we developed lipid-based nanoparticles, namely cubosomes, to encapsulate daptomycin for targeted delivery via lipid-mediated interactions. Daptomycin-loaded cubosomes synergistically killed 14 clinical MRSA isolates in vitro compared with daptomycin or cubosomes alone. This synergy between daptomycin and cubosome was mediated by cubosomes docking on the S. aureus cell
