Staphylococcus aureus is an important cause of bacteremia, and S. aureus bacteremia constitutes a serious condition with high morbidity and mortality, secondary to multiple complications including infective endocarditis and embolization. The incidence of bacteremia with S. aureus is increasing with more frequent use of medications that lower immune system response, and with the utilization of more invasive medical procedures. In addition, the emergence of resistant S. aureus isolates is becoming more common and can negatively affect the outcome of an individual if not diagnosed and managed properly. Health care workers encounter S. aureus bloodstream infections on a routine basis, and in certain situations, it becomes a very challenging infection to control. Because of the impact this entity has on health care costs and the increased use of resources, it is necessary to highlight the causes, clinical presentation, associated complications, and treatment measures. In this chapter, we will cover each of these points, with somewhat more emphasis on methicillin‐resistant S. aureus that is prevalent in both community and hospital settings and is more commonly associated with worsening prognosis and higher mortality.
