Where is Staphylococcus aureus found?
Staphylococcus aureus is a Gram-positive, round-shaped bacterium, a member of the Firmicutes, and is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin.
How many lineages does Staphylococcus aureus have?
Staphylococcus aureus can be sorted into ten dominant human lineages. There are numerous minor lineages as well, but these are not seen in the population as often. Genomes of bacteria within the same lineage are mostly conserved, with the exception of mobile genetic elements. Mobile genetic elements that are common in S. aureus include bacteriophages, pathogenicity islands, plasmids, transposons, and staphylococcal cassette chromosomes. These elements have enabled S. aureus to continually evolve and gain new traits. There is a great deal of genetic variation within the S. aureus species. A study by Fitzgerald et al. (2001) revealed that approximately 22% of the S. aureus genome is non-coding and thus can differ from bacterium to bacterium. An example of this difference is seen in the species' virulence. Only a few strains of S. aureus are associated with infections in humans. This demonstrates that there is a large range of infectious ability within the species.
How long does S. aureus last?
It is capable of generating toxins that produce food poisoning in the human body. Its incubation period lasts one to six hours, with the illness itself lasting from 30 minutes to 3 days. Preventive measures one can take to help prevent the spread of the disease include washing hands thoroughly with soap and water before preparing food. Stay away from any food if ill, and wear gloves if any open wounds occur on hands or wrists while preparing food. If storing food for longer than 2 hours, keep the food below 5 or above 63 °C.
How to prevent S. aureus?
Preventive measures include washing hands often with soap and making sure to bathe or shower daily. S. aureus is a significant cause of chronic biofilm infections on medical implants, and the repressor of toxins is part of the infection pathway. S. aureus can lay dormant in the body for years undetected.
What is the name of the bacterium that grows on blood agar plates?
In medical literature, the bacterium is often referred to as S. aureus, Staph aur eus or Staph a.. S. aureus appears as staphylococci (grape-like clusters) when viewed through a microscope, and has large, round, golden-yellow colonies, often with hemolysis, when grown on blood agar plates.
Where is S. aureus found?
In humans, S. aureus can be present in the upper respiratory tract, gut mucosa, and skin as a member of the normal microbiota. However, because S. aureus can cause disease under certain host and environmental conditions, it is characterized as a "pathobiont".
How does Staphylococcus aureus affect the body?
Epidemiology of Staphylococcus aureus. Staphylococcus aureus can cause illness by preformed toxin production as well as by infecting both local tissues and the systemic circulation. Disease transmission can occur in the following settings: Gastrointestinal: Staphylococcus aureus causes acute episodes of food poisoning via preformed enterotoxins.

Why is S. aureus a common cause of IE?
aureus is now the most common cause of IE in the industrialized world ( 125 ). Due to its propensity to cause severe disease and its frequent antibiotic resistance, S. aureus is a dreaded cause of IE. Although our ability to rigorously study IE was previously limited by its relative infrequency at any single institution, large multinational collaborations such as the International Collaboration on Endocarditis Prospective Cohort Study (ICE-PCS) ( 126) and robust population-level studies ( 127, – 129) have provided critical insights into the epidemiology and prognosis of IE in general and S. aureus IE in particular.
How much of the human population is contaminated with S. aureus?
Approximately 30% of the human population is colonized with S. aureus ( 1 ). Simultaneously, it is a leading cause of bacteremia and infective endocarditis (IE) as well as osteoarticular, skin and soft tissue, pleuropulmonary, and device-related infections.
What is the primary defense against S. aureus?
The primary defense against S. aureus infection is the neutrophil response. When S. aureus enters the skin, neutrophils and macrophages migrate to the site of infection. S. aureus evades this response in a multitude of ways, including blocking chemotaxis of leukocytes, sequestering host antibodies, hiding from detection via polysaccharide capsule or biofilm formation, and resisting destruction after ingestion by phagocytes.
How common are osteoarticular infections in children?
The incidence of osteoarticular infections in children ranges from 7 to 22 per 100,000 person-years based on studies from Europe ( 493, – 495 ). These infections are more common in males than in females (with incidences in French children of 24 per 100,000 person-years for boys and 19 per 100,000 person-years for girls) and in toddlers than in other age groups ( 494, 495 ). Some ethnic groups may be at higher risk, with Maori and Pacific Islander populations being overrepresented in a study involving 813 cases of acute OM in New Zealand ( 496 ). In the United States, CA-MRSA has become considerably more prominent as a cause of acute osteoarticular infections since 2000. In a study of 158 cases in Tennessee, the proportion of osteoarticular infections due to CA-MRSA rose from 4% to 40% from 2000 to 2004 ( 497 ). Similarly, the proportion of cases of acute OM due to CA-MRSA was 6% in 1999 to 2001 compared to 31% in 2001 to 2003 in Dallas, TX ( 498 ). In Houston, TX, between 2001 and 2010, 195 of 376 (52%) cases of S. aureus OM were due to MRSA ( 499 ).
What is the most common pathogen in osteoarticular infections?
S. aureus is the most common pathogen in all three major classes of osteoarticular infection, namely, osteomyelitis (OM) ( 382, – 392 ), native joint septic arthritis ( 393, – 401 ), and prosthetic joint infection (PJI) ( 402, – 406 ). As staphylococcal osteoarticular infections in children are common and have distinctive clinical and management issues compared to those in adults, we include an in-depth discussion of this important subpopulation.
How long should I take antibiotics for SAB?
The recommended duration of intravenous (i.v.) antibiotics for uncomplicated SAB is at least 2 weeks. In a recent prospective cohort study of uncomplicated SAB (as defined by IDSA criteria), receipt of antibiotic therapy for <2 weeks was associated with a relapse rate of 8% (compared to 0% for those treated for at least 2 weeks) ( 99 ). This relapse rate is consistent with the 6% rate of late complications (inclusive of relapse and metastatic complications) for intravascular catheter-associated SAB treated for <2 weeks identified in a 1993 meta-analysis of 11 studies ( 100 ). Although a few observational studies have suggested that as little as 7 days of i.v. antibiotics may be adequate (reviewed by Thwaites et al. [ 77 ]), such abbreviated courses must be regarded as investigational pending robust, generalizable evidence. Until such evidence exists, all patients with uncomplicated SAB should receive at least 2 weeks of i.v. antibiotics ( 73, 78, 79 ). Two-week courses of therapy, both with ( 101, – 104) and without ( 102) adjunctive aminoglycosides, have also been used successfully for uncomplicated, IDU-associated, right-sided S. aureus IE. Cure rates in these studies ranged from 77 to 94% ( 101, – 103, 105) and were similar for those who did and those who did not receive adjunctive aminoglycosides. However, cure rates were lower for patients who received glycopeptides (e.g., vancomycin and teicoplanin) than for those receiving antistaphylococcal penicillins ( 101, 105 ). Thus, patients being treated with vancomycin for right-sided IE should receive >2 weeks of therapy. For complicated SAB, 4 to 6 weeks of i.v. therapy has been the standard practice for over half a century and continues to be recommended ( 73, 75, 79, 106 ).
What causes a nidus to form?
The formation of a nidus for bacterial colonization and infection begins with damage to the cardiac endothelium, either by direct trauma (e.g., intravascular catheters and electrodes, injected particulate matter from injection drug use, or turbulent blood flow resulting from valvular abnormalities) or inflammation (e.g., secondary to rheumatic heart disease or degenerative valvular disease). The exposure of subendothelial cells elicits the production of extracellular matrix proteins and tissue factor and the deposition of fibrin and platelets to form sterile vegetations. If these thrombotic vegetations become colonized by bacteria, IE can result ( 155 ).
What is the most common cause of S. aureus infection?
Staphylococcus aureus is a virulent pathogen that is currently the most common cause of infections in hospitalized patients. S. aureus infection can involve any organ system. The success of S. aureus as a pathogen and its ability to cause such a wide range of infections are the result of its extensive virulence factors. The increase in the resistance of this virulent pathogen to antibacterial agents, coupled with its increasing prevalence as a nosocomial pathogen, is of major concern. The core resistance phenotype that seems to be most associated with the persistence of S. aureus in the hospital is methicillin resistance. Methicillin resistance in nosocomial S. aureus isolates has been increasing dramatically in United States hospitals and is also associated with resistance to other useful antistaphylococcal compounds. Possible ways to decrease the incidence of nosocomial S. aureus infections include instituting more effective infection control, decreasing nasal colonization, developing vaccines, and developing new or improved antimicrobials.
How to reduce the incidence of S. aureus?
aureus infections include instituting more effective infection control, decreasing nasal colonization, developing vaccines, and developing new or improved antimicrobials.
