Staphylococcus aureus is a bacterium that commonly colonizes the skin and mucous membranes of humans and animals. It is a major cause of hospital-acquired infections and is also responsible for a wide range of community-acquired infections, such as skin and soft tissue infections, pneumonia, and septicemia. Research on Staphylococcus aureus focuses on understanding its pathogenicity, antibiotic resistance mechanisms, and developing new strategies for prevention and treatment of infections caused by this bacterium. Additionally, studies also aim to explore the epidemiology and transmission dynamics of Staphylococcus aureus to better control and prevent its spread in healthcare settings and the community.
