Staphylococcus aureus, commonly known as "staph," is a type of bacteria that is frequently found on the skin and in the nasal passages of healthy people. While S. aureus is usually harmless, it can cause a range of illnesses when it enters the body, from minor skin infections to life-threatening diseases. S. aureus can cause a variety of infections, including skin and soft tissue infections, bloodstream infections, pneumonia, and endocarditis. It is a leading cause of hospital-acquired infections and can be particularly dangerous for people with weakened immune systems. Staphylococcus aureus is a gram-positive bacterium that is a common cause of infections in both community and healthcare settings. It is a highly adaptable organism, able to survive and thrive in a variety of environments, including the human body. S. aureus infections range from minor skin infections to life-threatening conditions such as sepsis, pneumonia, and endocarditis. S. aureus produces a wide range of virulence factors that contribute to its pathogenicity. These include surface proteins that promote adhesion to host cells, toxins that damage host tissues, and enzymes that facilitate the spread of the bacterium. The ability of S. aureus to produce these factors is controlled by a complex regulatory network that responds to changes in the environment.
