Staphylococcus aureus is a coagulase-positive, Gram-positive coccus of the family Staphylococcaceae, commonly carried on the skin and in the nares of healthy individuals. It is one of the most clinically significant bacterial pathogens, causing a wide spectrum of diseases from skin infections and food poisoning to endocarditis, osteomyelitis, and sepsis, with methicillin-resistant strains (MRSA) posing a major public-health threat. Genomically, S. aureus features a highly conserved core genome alongside a rich mobile genetic element repertoire encoding toxins, immune evasion factors, and antimicrobial resistance determinants.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
