S. aureus *testing results* positive for the slide coagulase test, tube coagulase test, and DNAse. It can grow in media containing up to 10% NaCl. Diagnostic procedures procedures include Gram stain, appropriate-site aerobic culture and teichoic acid antibody test
S. aureus *virulence factors* antiphagocytic proteins, lipase production, coagulase, enterotoxins, and exotoxins
