S. aureus acquired from an external source could be the cause of an infection when inoculated into an open wound. Therefore, coagulase negative slides must undergo another coagulase test but this time in the form of a tube to confirm the result. the drop of H2O2. The staphylococcal toxin must be separated from food constituents and concentrated to detect trace amounts. Both community-associated and hospital-acquired infections with Staphylococcus aureus have increased in the past 20 years, and the rise in incidence has been accompanied by a rise in antibiotic-resistant strains—in particular, methicillin-resistant S aureus (MRSA) and, more recently, vancomycin-resistant strains.
