Correct option is C
Staphylococcus aureus is a Gram-positive bacterium known for both food poisoning and a wide spectrum of infections, from superficial skin infections to severe invasive diseases.
Option 1 is correct:
S. aureus infections vary from boils, abscesses, and cellulitis to life-threatening diseases such as necrotizing pneumonia, endocarditis, and sepsis.
Option 2 is also correct: The virulence of
S. aureus is largely due to its toxin production, classified into:
Pore-forming toxins (PFTs) like alpha-toxin, which lyse host cells,
Exfoliative toxins (ETs) responsible for conditions like scalded skin syndrome,
Superantigens (SAgs) like enterotoxins and toxic shock syndrome toxin (TSST-1), which overstimulate the immune system.
Since both options are scientifically accurate, the correct answer is Option (c).
