- Staphylococcus aureus seen under microscope


Staphylococcus aureus is a Gram-positive, round-shaped (coccus) bacterium that commonly colonizes the skin and mucous membranes of humans and animals. It is a facultative anaerobe and non-motile organism.
It is a member of the genus Staphylococcus, and one of the most significant pathogens in both community-acquired and hospital-acquired infections.
Microscopically, S. aureus appears as clusters resembling grapes and stains purple under Gram staining due to its thick peptidoglycan layer.
