Novel erythromycin lipid nanoformulations for aquaculture applications

The nanoemulsion (F4) kept higher ERY content at early time points and showed equal or lower MICs than free ERY against selected Aeromonas spp. The dispersions can be spray-dried to a powder or incorporated into fish feed by extrusion or post-pellet coating-routes rarely reported for ERY in aquaculture. These results support further development of ERY nanoformulations against aquaculture pathogens.
