Whole-genome sequencing reveals the virulence and drug resistance potential of Staphylococcus aureus from milk in Yunnan, southwest China

This study revealed the contamination status of Staphylococcus aureus in bovine milk in Yunnan Province, and analysed the homology between Staphylococcus aureus strains by PFGE technique, and analysed the drug resistance phenotypes and virulence genes of Staphylococcus aureus by drug sensitivity assay and whole genome sequencing, providing a certain data base for the study of foodborne pathogenic bacteria in bovine milk in Yunnan It also provides a scientific basis for the prevention and control of foodborne pathogens in milk.
