Staphylococcus aureus is the most common pathogen involved in skin infections worldwide, regardless of the patient’s age, the climate or geographical area. The main skin clinical manifestations can be linked to a few toxins produced by the bacteria.
Staphylococcus is a genus of Gram-positive bacteria known for their spherical or grape-like clustered shape under a microscope. They are commonly found in various environments, including on the skin and mucous membranes of humans and animals.
Clinical Manifestations. Staphylococci can cause many forms of infection. (1) S aureus causes superficial skin lesions (boils, styes) and localized abscesses in other sites. (2) S aureus causes deep-seated infections, such as osteomyelitis and endocarditis and more serious skin infections (furunculosis).
Staphylococcus aureus is a major human pathogen that causes a wide range of clinical infections. It is a leading cause of bacteremia and infective endocarditis as well as osteoarticular, skin and soft tissue, pleuropulmonary, and device-related infections.
The most common sites of S. aureus infection are the skin and soft tissue, with over 75% of these due to MRSA (125). Staphylococcus aureus possesses a wide range of virulence factors (e.g. enterotoxins and cytotoxins) that allow it to colonise and overcome the host resulting in major illnesses.
Members of the genus Staphylococcus still represent a topic of great relevance due to the numerous types of infections they cause in humans and animals. Staphylococci have emerged as important pathogens for both nosocomial and community-acquired infections in people.
