Final answer:
The normal flora of the skin consists of commensal organisms that protect the skin from infection. Staphylococcus epidermidis, Staphylococcus hominis, and Staphylococcus aureus are commonly found on the skin.

They protect the skin from pathogenic infection by inhibiting the colonization of transient microbes. The major organisms commonly found on the skin include Staphylococcus epidermidis, Staphylococcus hominis, and Staphylococcus aureus.
