TYPE OF DISEASE OR INFECTION
Staphylococcus aureus is one of the most important organisms that cause community-acquired skin and soft tissue infections as well as life-threatening nosocomial infections. S. aureus affects the bloodstream, skin, soft tissues and lower respiratory tracts. S. aureus is the leading cause of necrotizing pneumonia, bacteremia, infective endocarditis, osteoarticular, skin, soft tissue, pleuropulmonary, device-related and various surgical wound infections. The infections of skin and soft tissue could be boils, carbuncles, impetigo and cellulitis. If the infections get serious, manifestations could be ventilator‑associated necrotizing pneumonia, necrotizing fasciitis, endocarditis and sepsis. In addition to those infections, S. aureus is also responsible for

aureus strains that carry virulence factors and are resistant to beta-lactam antibiotics. It is noted that community-associated MRSA infections might first have emerged among indigenous people in Western Australia in early 1990s. The first documented cases in the United States came from four healthy children in rural Minnesota and North Dakota in 1997 to 1999. Years after MRSA, vancomycin-resistant S. aureus cases were also reported (6). In the industrialized world, the population incidence of S. aureus bacteremia ranges from 10 to 30 per 100,000 persons in a year. Rates of getting infections are high in the first year of life. A low incidence takes place throughout young adulthood and a gradual rise in incidence occurs with advancing age. Infective endocarditis incidence was originally 1.5 to 6 per 100,000 person in a year. It has increased to 16.6 per 100,000 person in a years in 2006. This was driven by an increase in the incidence of S. aureus infective endocarditis
