In vitro effect of zinc oxide nanoparticles on Staphylococcus aureus isolated from Layer Chickens

This study aimed to evaluate the antibacterial activity of zinc oxide nanoparticles (ZnO-NPs) on Staphylococcus aureus (S. aureus) isolated from layer chickens using minimum inhibitory concentration test (MIC). A total number of 120-layer chicken samples from hock joints and livers were collected un...
