Bullous impetigo is caused by staph bacteria, which reduce skin cells' ability to stick to each other, states MedicineNet.com. This allows blisters filled with yellowish fluid to form. The blisters break open easily, leaving a red, open wound. Dark scabs form and eventually heal. Bullous impetigo is often found on the buttocks and other parts of the trunk.
The bumps that develop at the beginning of non-bullous impetigo look like insect bites, MedicineNet.com says. The bumps turn into small blisters and fill with pus. The scabs that form are a distinctive light brown, honey color. This infection is caused by either staph or strep bacteria.
Non-bullous impetigo most commonly occurs on the face, although it also appears on arms and legs, explains MedicineNet.com. The nearest lymph glands are sometimes swollen, but they are not sore.
Both types of impetigo occur more often in children, but adults also contract the infections, MedicineNet.com notes. Children between the ages of 2 to 5 are most likely to develop the condition. Although it is contagious, impetigo responds well to topical and oral antibiotics.Learn more about Skin Conditions
