What are some common types of bacterial skin infections?

The following are common bacterial skin infections:​


Infection Symptoms​ Treatment
Erysipelas

A skin infection caused by hemolytic streptococci.  This condition usually affects the face or legs; in rare cases, it affects an area that was injured or where the skin is cut.  Many people have a fever or flu-like symptoms which may include:

  • Shiny, red raised rash
  • Small blisters
  • Enlarged and tender lymph nodes

Antibiotics

Erythrasma

A bacterial skin infection of the top layers of the skin.  This condition mainly affects obese adults and people with diabetes and usually appears in areas on the body where skin touches skin, such as under the breast and in the groin area.  Symptoms may include irregular pink patches that turn into brown scales.

Topical and oral antibiotics 

Impetigo

A skin infection caused by a streptococcal or staphylococci infection.  Symptoms include pus-filled blisters or pustules.  Blisters can range in size from peas to large rings and oozing honey-colored liquid often occurs with yellowish scabs.  Impetigo tends to occur on the face, arms or legs and is most common in children; it is very contagious.  Symptoms usually do not affect the whole body.

Immediate treatment may help prevent impetigo from infecting deeper layers of skin.  Treatment often includes antibiotics.  

Paronychia

A skin infection around a fingernail or toenail; this infection can be caused by a break in the skin due to a hangnail, manicure, fingernail biting or other chronic irritation.  Symptoms may include pain and pus-filled abscess.  

Hot compresses, soaking in warm water, cutting the abscess to drain the pus, antibiotics

If caused by a fungus, an application of antifungal cream or another antifungal medication
