Skin Infections caused by Staphylococcus Aureus

What is Staphylococcus Aureus (S. Aureus)?

Staphylococcus aureus, or S. aureus, is a type of bacteria that is commonly found on the skin and nose of many people. It typically causes minor skin infections, but can cause more serious infections in some cases. These infections may be red, swollen, painful, and can include pus and other drainage.

Skin Infections Caused by S. Aureus

S. aureus can cause a variety of skin infections. These include folliculitis, impetigo, cellulitis, abscesses, and boils.


Folliculitis is an infection of the hair follicles. It is characterized by red, tender bumps, and sometimes pustules. In some cases, the infection can spread to surrounding skin tissue, resulting in a more serious infection.


Impetigo is a contagious skin infection that is characterized by red sores and blisters, usually around the mouth and nose. These sores can be crusty and itchy. Impetigo is often spread in close contact situations, such as day care centers.


Cellulitis is a bacterial infection that affects the deeper layers of the skin. It is characterized by red, tender skin that is warm to the touch. The infection can spread quickly, so treatment should be sought immediately.


An abscess is a collection of pus that is typically surrounded by inflamed tissue. It is caused by an infection, typically bacterial. Abscesses can be painful and can range in size from very small to large.


A boil is an infection of a hair follicle, typically on the face, neck, or upper back. It is characterized by a red, tender bump that is filled with pus.

Treatment of S. Aureus Skin Infections

Treatment for S. aureus skin infections typically involves antibiotics. These antibiotics can be in pill form or in a topical ointment.

Prevention of S. Aureus Skin Infections

The best way to prevent S. aureus skin infections is to practice good hygiene. This includes washing hands regularly with soap and water, avoiding contact with people who have active skin infections, and keeping cuts and scrapes clean and covered. It is also important to practice general skin care, such as avoiding certain clothing that can trap sweat and cause irritation and moisture.
