Which bacteria causes a straph infection?

A staph infection is primarily caused by Staphylococcus aureus, a type of bacteria commonly found on the skin and in the nasal passages of healthy individuals. This bacteria can lead to various infections, ranging from mild skin issues, like boils and cellulitis, to more severe conditions, including pneumonia and bloodstream infections. Methicillin-resistant Staphylococcus aureus (MRSA) is a notable strain that is resistant to many antibiotics and poses a greater treatment challenge.
