Summary Introduction
Introduction:
The Staphylococcus aureus is a Gram-positive round-shaped bacterium commonly found in the nose, on the skin, and in the respiratory tract. Normally, it is nonpathogenic, but when the immune system of the body is weak, it becomes pathogenic. It can cause skin infections, a respiratory infection like sinus, and food poisoning. Penicillin G is used to protect the host from S. aureus infections.
