Bacterial skin infection is caused by a pathogenic bacterium Corynebacterium minutissimum, which can be diagnosed by exposing the skin site to coral-red fluorescence under a Wood’s lamp and conducting skin scraping.
This pathogen is an ordinary part of the flora. Bacterial skin infection is divided into two types:
Interdigital erythrasma might be asymptomatic and is the most common bacterial skin infection. Pathogenic bacterium may also cause interdigital foot infections.
Bacterial infection affects the top skin layer and does not spread to the nails and hair. The border between the affected and healthy skin area is clearly visible. The reasons for erythrasma are as follows:
- poor hygiene;
- weakened immune system;
- excessive sweating.
The duration of the infectious disease can range from several months to several years. Complications after erythrasma are rare and depend on the symptoms or the infection spread.
In rare cases, erythrasma complications can be severe infectious diseases caused by a systemic inflammatory reaction when entering the infectious agent the bloodstream. Patients with weakened immunity are a major risk group for erythrasma complications.
Photodynamic therapy (PDT) is also used to treat erythrasma in dermatology. This method helps to inhibit the growth of microorganisms by the photodynamic action of red light.
It is recommended to maintain healthy weight, normal blood sugar level, and good hygiene as prevention of erythrasma.
