Staphylococcus aureus is a spherical, Gram-positive coccus belonging to the family Staphylococcaceae. The genome of this species is approximately 2.8 Mb (million bases) in length. S. aureus virulence factors are encoded by phages, chromosome segments, and plasmids, which contain antibiotic-resistance genes such as those present in methicillin-resistant Staphylococcus aureus (MRSA).
Staphylococcus aureus can be found on the skin and mucous membranes of healthy individuals, but any damage to the integrity of the skin and mucous membranes allow Staphylococci to enter the wound, colonize the area and cause infection. Since these microbes live on the skin, they can be easily transmitted between individuals and are usually present in hospital infections.
Staphylococcus aureus can cause various infections ranging from mild skin infections such as impetigo, to invasive diseases and toxin-induced diseases. Exotoxins production in some S. aureus strains can cause toxic shock syndrome.
Important Note
Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. The correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".
Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings, and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.
At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
