In intro it is written that : Staphylococcus aureus is a Gram-positive, round-shaped bacterium that is a member of the Firmicutes, and """it is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin."""

However in Role in health part it is written as : Role in health

"""In humans, S. aureus is not part of the normal microbiota present in the upper respiratory tract or gut mucosa or on the skin; rather, when it is prevalent here, it is a colonization."""
