Staphylococcus aureus adapts to the skin, overcoming its defenses to cause infections. This review explores how the bacteria persists in skin conditions like atopic dermatitis and diabetic wounds.
Area of Science:
- Microbiology
- Dermatology
- Infectious Diseases
Background:
- Staphylococcus aureus commonly colonizes the nose in 20-30% of the population.
- Nasal colonization by S. aureus is a known risk factor for infections at other body sites.
- The skin presents a hostile environment due to desiccation, low pH, shedding, and antimicrobial peptides.
Purpose of the Study:
- To review current knowledge on Staphylococcus aureus adaptation to diverse skin conditions.
- To understand how S. aureus causes persistent and recurrent skin infections.
Main Methods:
- Literature review of studies on Staphylococcus aureus skin colonization and infection.
- Analysis of bacterial adaptation mechanisms to skin-specific stressors.
- Examination of S. aureus behavior in pathological skin conditions.
Main Results:
- Staphylococcus aureus possesses remarkable adaptability to overcome skin's natural defenses.
- The bacterium efficiently adapts to stressors in skin under pathological conditions like atopic dermatitis and diabetic wounds.
- Understanding these adaptations is crucial for managing persistent S. aureus skin infections.
Conclusions:
- Staphylococcus aureus demonstrates significant resilience and adaptability to the skin environment.
- Pathological skin conditions create unique challenges and opportunities for S. aureus colonization and infection.
- Further research into S. aureus adaptation mechanisms can inform novel therapeutic strategies.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
