What does the disease mean? Impetigo is a skin disease caused by the penetration into the hair follicles of Staphylococcus aureus, streptococcus or these bacteria simultaneously. The disease is characterized by high infectiousness. As a rule, children are under risk while adults are infected because of damage to the skin during shaving. Also, the disease can be a consequence of other skin problems, for example, severe itching.
Why does Impetigo occur? As a rule, it is caused by staphylococci, sometimes streptococci, or a combination of both. These bacteria, mainly, are part of the microflora of the skin and are activated in case of a decrease in the protective function of the skin, and with a weakening of immunity. Most often impetigo affects the skin of the hands and face. Impetigo can be caused by one of two pathogens: Staphylococcus aureus and hemolytic streptococcus.
Staphylococcus aureus is a bacterium that is present in the body of 25-40% of people. It is found in the mucous membrane of the nose, throat, vagina. Staphylococcus aureus is a conditionally pathogenic microorganism. That is, it usually does not cause any diseases. But under certain conditions, staphylococcosis becomes pathogenic. It detects toxins that cause pathological changes in the organs and tissues of a person. Hemolytic streptococcus is also a conditionally pathogenic bacterium. Normally inhabits the mucous membranes of the mouth, nose, and throat of many people. Can isolate toxins that lead to pathological changes. It is the causative agent of many diseases, including impetigo, erysipelas, tonsillitis, etc.
