Question

In the question below is given a statement followed by two options numbered 1 and 2. Based on this choose the correct option. Statement: S. aureus is a major pathogen that causes food poisoning and a wide variety of infectious diseases. Option 1: S. aureus infections range in severity from mild skin infections to severe necrotizing pneumonia. Option 2: The three major groups of S. aureus toxins are the pore-forming toxins (PFTs), exfoliative toxins (ETs), and superantigens (SAgs).
Options:

A.

If only option 1 is correct

B.

If only option 2 is correct

C.

If both 1 and 2 are correct

D.

If both 1 and 2 are incorrect

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).
