Why Is It Not Surprising That Staphylococci Are the Leading

Why is it not surprising that Staphylococci are the leading cause of wound infections?

A) This genus is readily present as a part of the normal microbiota on most people's skin, so it could easily enter wounds.
B) Members of this genus are all particularly virulent and highly capable of causing numerous infections.
C) Staphylococci cannot be eradicated from the skin due to multidrug resistance in most members of the genus. Drugs simply don't kill them.
D) Staphylococci acquire antibiotic resistance very readily, making them hard to eliminate by pre-surgical antibacterial soaps. As such, they commonly infect surgical wound sites.
E) Staphylococci form endospores, so even with appropriate control measures, there is a high risk that spores will enter a wound and cause infection.
