Presentation
Typification of strains through PFGE and spa-typing revealed that some carriers present the same strain, whereas others present different strains along the period of persistence. Almost all strains induced a strong biofilm formation. [ncbi.nlm.nih.gov]
Interestingly, some clones belonging to different CCs presented a higher PFGE similarity than clones included in the same CC. [doi.org]
Entire Body System
- Sepsis
Staphylococcal sepsis is a leading cause of shock, circulatory collapse, and death in people with severe burns over large areas of the body. When untreated, S. aureus sepsis carries a mortality (death) rate of over 80%. [medicinenet.com]
These metabolic changes in the urine preceded the clinical severe sepsis phenotype, suggesting that detection of the extent of metabolic disruption can aid in the early identification of a sepsis phenotype in advance of the clinical diagnosis. [ncbi.nlm.nih.gov]
- Wound Infection
BACKGROUND: Wound infections after adult spinal deformity surgery place a high toll on patients, providers, and the healthcare system. [ncbi.nlm.nih.gov]
One way of getting MRSA is to make direct contact with a wound infected with MRSA. Also, if someone with a wound infected with MRSA wipes the wound with a towel or other item, the bacteria will spread to that item. [my.clevelandclinic.org]
In case of a weakened immune system, however, is can cause wound infections and even sepsis. Many variants of Staphylococcus aureus are resistant against common antibiotics. [dzif.de]
- Chronic Infection
Similarly, low virulent EDCC 5464 was isolated from chronic implant-associated bone infections infection whereas EDCC 5458 was obtained from acute implant-associated bone infections. [ncbi.nlm.nih.gov]
This process has been hypothesized to contribute to chronic infection of the pathogen. Within this project we are investigating virulence factors involved in this evasive strategy of S. aureus. [biozentrum.uni-wuerzburg.de]
Pathogenesis of S. aureus Biofilms Chronic S. aureus infections affect mostly bone and joints, and typically include foreign-body infections. [genomic.ch]
Indeed, P. aeruginosa strains isolated from early infection outcompete S. aureus, as previously described, while strains isolated from chronic infection are less aggressive and can be co-cultivated with S. aureus19,20. [nature.com]
One vaccine which showed such potential in treating chronic infections is a quadrivalent vaccine comprising cell wall and membrane-associated proteins that has significantly reduced MRSA osteomyelitis infection in rabbits when co-administered with vancomycin [doi.org]
- Malaise
Symptoms of these infections include: difficulty breathing, malaise, fever, or chills. If you suspect you may have an infection with S. aureus contact your health care provider. [health.state.mn.us]
[…] hospital settings; surface infections include impetigo, folliculitis, abscesses, boils, infected lacerations; deep infections include endocarditis, meningitis, septic arthritis, pneumonia, osteomyelitis; systemic infection may cause fever, headache malaise [msdsonline.com]
When symptoms are present, however, watch for drooling, fever, difficulty swallowing and malaise, says the National Institutes of Health. The gums may also bleed and become red, swollen and tender. [colgate.com]
- Constitutional Symptom
Some will have constitutional symptoms: low-grade fever, malaise, lymphadenopathy, and headache. Pain will vary. [unboundmedicine.com]
[…] osteomyelitis): In children, sudden onset of fever and bony tenderness or a limp; pain may be throbbing and severe; however, presentation in neonates can be subtle Septic arthritis: Decreased range of motion, warmth, erythema, and tenderness of the joint with constitutional [emedicine.medscape.com]
Cardiovascular
- Hypotension
Activated T-cells vigorously proliferate and release proinflammatory cytokines plus chemokines that can elicit fever, hypotension, and other ailments which include a potentially lethal shock. [ncbi.nlm.nih.gov]
[…] exfoliative toxins; my be colonized during delivery resulting in sepsis meningitis; toxic shock syndrome is an acute multi-system illness caused by TSST-1 a super antigen; characterized by sudden onset, high fever, vomiting, profuse watery diarrhea, myalgia, hypotension [msdsonline.com]
Liver, Gall & Pancreas
- Jaundice
A 55-year-old man with history of chronic hepatitis B cirrhosis presented to an emergency department in California with abdominal pain, constipation, and jaundice. [ncbi.nlm.nih.gov]
[…] osteomyelitis,62 and acute osteomyelitis involving other sites such as the clavicle63 and the pubis.64 We have also found that combination therapy with fusidic acid may be synergistic in the treatment of S aureus meningitis.54 Because of the high risk of jaundice [jamanetwork.com]
Hematemesis, hematobilia, and jaundice suggest rupture of a hepatic artery MA; arterial hypertension and hematuria suggest rupture of a renal MA; and massive bloody diarrhea suggests the rupture of an ECMA into the small or large bowel. [doi.org]

Microbiology
- Gram-Positive Bacteria
Many surface proteins are anchored to the cell wall of Gram-positive bacteria and are involved in the pathogenesis of these organisms. [ncbi.nlm.nih.gov]
See all Hide authors and affiliations Science 07 Apr 1995: Vol. 268, Issue 5207, pp. 103-106 DOI: 10.1126/science.7701329 Abstract Many surface proteins are anchored to the cell wall of Gram-positive bacteria and are involved in the pathogenesis of these [doi.org]
Peptidoglycan from S. aureus PGN-SA is peptidoglycan (PGN) purified from the Gram-positive bacterium, Staphylococcus aureus. PGN is a major surface component of Gram-positive bacteria. [invivogen.com]
ABSTRACT The transfer of gram-positive bacteria, particularly multiresistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE), among patients is a growing concern. [jcm.asm.org]
- Candida
We describe a novel strategy by which S. aureus is able to invade host tissue and disseminate via adherence to the invasive hyphal elements of Candida albicans. [ncbi.nlm.nih.gov]
Infections may require specific treatment such as antibiotics for streptococcal pharyngitis, topical antifungal or oral antifungal agent for candida infection. [dermnetnz.org]
- Gram-Positive Coccus

This gram positive coccus often produces colonies which have a golden-brown color. Micrococcus luteus. Circular, pinhead colonies which are convex with entire margins. This gram positive coccus produces a bright yellow, non-diffusable pigment. [academic.pgcc.edu]
Abstract Staphylococcus aureus is a facultative, Gram-positive coccus well known for its disease-causing capabilities. [ncbi.nlm.nih.gov]
A Gram-positive coccus that is often found colonising on the skin of the anterior nares, axilla, and perineum. The methicillin (flucloxacillin) resistant version (MRSA) is a particular infection control hazard. [gloshospitals.nhs.uk]
Microbiology S. aureus is a Gram-positive coccus, which on microscopy, appears in clusters. It is a facultative anaerobe which grows readily on standard blood agar. [ganfyd.org]
Treatment
Contact laser treatment caused a focal temperature increase up to 58°C, whereas plasma treatment led a uniform temperature distribution on the disc within safe limits. [ncbi.nlm.nih.gov]
Prognosis
Long-term prognosis for adult cases of NP currently remains undocumented. [ncbi.nlm.nih.gov]
Prognosis[edit] The prognosis of SSSS in children is excellent, with complete resolution within 10 days of treatment, and without significant scarring. [en.wikipedia.org]
Etiology
Over the last decades Staphylococcus aureus (SA) has become the dominant etiology of native valve infective endocarditis, with the community-acquired methicillin-sensible Staphylococcus aureus (CA-MSSA) strains being the prevailing type. [ncbi.nlm.nih.gov]
Epidemiology
Conclusion The data suggest that some strains can adapt and colonize new epidemiologically unrelated habitats. [ncbi.nlm.nih.gov]
Thus, it is very useful and important molecular tool in understanding the potential epidemiological background of the strains. 3.1.4. [intechopen.com]
International surveillance Joana Rolo, Ons Bouchami, Nuno Faria, Maria Miragaia In Europe the epidemiology of nosocomial MRSA is well understood, but the epidemiology of CA-MRSA is incompletely documented due to poor geographic coverage and outdated data [itqb.unl.pt]
Pathophysiology
All efforts by S. aureus to resist neutrophil-mediated killing stress the importance of these mechanisms in the pathophysiology of staphylococcal diseases. [annualreviews.org]
Objectives: Review the pathophysiology of S aureus infections. Describe the workup of a patient with staphylococcus infection. Summarize the treatment options for staphylococcus infections. [ncbi.nlm.nih.gov]
Prevention
Thus we must elucidate the mechanisms behind S aureus nasal carriage and infection to be able to develop new preventive strategies. [ncbi.nlm.nih.gov]
“To date, there is no licensed vaccine available to prevent invasive S. aureus disease. [pfizer.com]
This finding underscores the importance of extending efforts to prevent and reduce the spread of methicillin-resistant S. aureus beyond inpatient facilities. [doi.org]
Use contact precautions (e.g., procedures to prevent droplet or aerosols). Post signs at the entrance to patient area. Single patient rooms may be used with designated toilets and sinks. [ccohs.ca]
