Final answer:
Staphylococcus epidermidis is a normal intestinal organism frequently found near the skin of the perineum. It helps protect the skin from pathogenic infection.
Step-by-step explanation:
The normal intestinal organism frequently found near the skin of the perineum is Staphylococcus epidermidis. This bacterium is part of the skin's normal microbiota and is commonly found on healthy human skin. Staphylococcus epidermidis, along with other bacteria, helps to protect the skin from pathogenic infection by producing antimicrobial substances and outcompeting other microbes that land on the surface of the skin.
