Prevention of S. aureusinfections remains challenging. Despite many efforts, a routine vaccination for S. aureusinfections has remained elusive. As a result, efforts have relied on infection control methods such as hospital decontamination procedures, handwashing techniques, and MRSA transmission prevention guidelines. Topical antimicrobials such as mupirocin can be used to eliminate nasal colonization in some nasal carriers. However, usage is controversial.

What is Staphylococcus aureus?

Last Update: August 23, 2020. Continuing Education Activity. Staphylococcus aureus is a gram-positive bacteria that cause a wide variety of clinical diseases. Infections caused by this pathogen are common both in community-acquired and hospital-acquired settings. The treatment remains challenging due to the emergence of multi-drug resistant strains ...

What is the color of a staph?

Staphylococcus aureus is Gram-positive bacteria (stain purple by Gram stain) that are cocci-shaped and tend to be arranged in clusters that are described as “grape-like.” On media, these organisms can grow in up to 10% salt, and colonies are often golden or yellow (aureus means golden or yellow). These organisms can grow aerobically or anaerobically (facultative) and at temperatures between 18 C and 40 C. Typical biochemical identification tests include catalase positive (all pathogenic Staphylococcusspecies), coagulase positive (to distinguish Staphylococcus aureusfrom other Staphylococcusspecies), novobiocin sensitive (to distinguish from Staphylococcus saprophyticus), and mannitol fermentation positive (to distinguish from Staphylococcus epidermidis). [4][1] MRSA strains carry a mecgene on the bacterial chromosome, which is a component of the larger Staphylococcal chromosomal cassette mec(SCCmec) region, conferring resistance to multiple antibiotics depending on the SCCmectype.[2] The mecgene encodes the protein PBP-2a (penicillin-binding protein 2a). PBP-2a is a penicillin-binding protein (PBP), or essential bacterial cell wall enzyme that catalyzes the production of the peptidoglycan in the bacterial cell wall. PBP-2A has a lower affinity to bind to beta-lactams (and other penicillin-derived antibiotics) when compared to other PBPs, so PBP-2A continues to catalyze the synthesis of the bacterial cell wall even in the presence of many antibiotics. As a result, S. aureusstrains that synthesize PBP-2A can grow in the presence of many antibiotics, and these MRSA strains are resistant to many antibiotics. MRSA strains tend to be resistant to methicillin, nafcillin, oxacillin, and cephalosporins. [2][4]

What are the most common infections caused by S. aureus?

aureusare one the most common bacterial infections in humans and are the causative agents of multiple human infections, including bacteremia, infective endocarditis, skin and soft tissue infections (e.g., impetigo, folliculitis, furuncles, carbuncles, cellulitis, scalded skin syndrome, and others), osteomyelitis, septic arthritis, prosthetic device infections, pulmonary infections (e.g., pneumonia and empyema), gastroenteritis, meningitis, toxic shock syndrome, and urinary tract infections.[6] Depending on the strains involved and the site of infection, these bacteria can cause invasive infections and/or toxin-mediated diseases. [6][7] The pathophysiology varies greatly depending on the type of S. aureusinfection.[6] Mechanisms for evasion of the host immune response include the production of an antiphagocytic capsule, sequestering of host antibodies or antigen masking by Protein A, biofilm formation, intracellular survival, and blocking chemotaxis of leukocytes. [8][7] Binding of the bacteria to extracellular matrix proteins and fibronectin in infectious endocarditis is mediated by bacterial cell wall-associated proteins such as fibrinogen-binding proteins, clumping factors, and teichoic acids.[7] Also, Staphylococcal superantigens (TSST-1 or toxic shock syndrome toxin 1) are important virulence factors in infectious endocarditis, sepsis, as well as toxic shock syndrome. [9][10] Pneumonia infections are associated with the bacterial production of PVL (Panton-Valentine leukocidin), Protein A, and alpha-hemolysin, and infections are more common following influenza virus infection as well as a diagnosis of Cystic Fibrosis.  Prosthetic device infections are often mediated by the ability of S. aureusstrains to form biofilms as well as communicate using quorum sensing in a bacterial cell density-dependent manner.  [11]

How long does it take to treat S. aureus?

When prescribing antibiotics, one should limit the duration to no more than 7 to 10 days for most infections. The reason is that the empirical prescription of antibiotics has led to the development of resistant strains. Pharmacists should coordinate with the clinician to target antimicrobial therapy, and nursing can chart the progress so modification to the regimen can be made if treatment is ineffective. This kind of interprofessional coordination is necessary to treat such infections with precision.

How to diagnose S. aureus?

In many cases, routine cultures will reveal the diagnosis (i.e.,blood, sputum); however, RT-PCR (real-time PCR) for 16S rRNA genes may be necessary in some cases. Drug susceptibility testing often is required to guide treatment.  If patient samples are collected for pathogen identification in the microbiology laboratory, caution must be exercised as the presence of S. aureusin the skin or mucous membrane does not necessarily indicate infection because these organisms are frequently members of the normal flora. [4]

Is Staphylococcus aureus transmitted?

Transmission is typically from direct contact. However, some infections involve other transmission methods.[4] Staphylococcus aureus is a major bacterial human pathogen that causes a wide variety of clinical manifestations.[1] . Infections are common both in community-acquired as well as hospital-acquired settings and treatment remains challenging ...

How to diagnose staph infection?
