摘　　要：Introduction:Staphylococcus aureus is one of the main pathogens in humans.Also,this bacterium can be colonized in the nose.The spa gene is present in all strains of Staphylococcus aureus(S.aureus)and can be used to identify species and toxins such as Panton-Valentine Leukocidin(PVL)that can affect a wide range of skin,soft tissue,and necrotizing pneumonia.Arthritis and life-threatening infections.This study aimed to investigate the effect of genetic diversity and phylogenetic relationships on different strains of Staphylococcus aureus in clinical specimens.Methods:This review study was conducted in 2021 by searching for keywords such as genetic diversity,phylogenetics,and Staphylococcus aureus in reputable databases such as pub med and google scholar.Finally,30 articles were found,of which 30 articles were used out of 26 articles.Results:In general,23%and 18%of health care workers and patients were carriers,respectively.The incidence of methicillin-resistant Staphylococcus aureus(MRSA)is higher in the relevant population.The molecular types of MRSA isolates indicate that the most common virulence gene is Hla,and the most common type of SCCmec is SCCmec type III.Conclusion:Sites with high risk of Staphylococcus aureus should be highly protected,and relevant personnel should be paid attention and health management.
