[Methicillin-resistant Staphylococcus aureus in dermatology].

Staphylococcus aureus (SA) is among the most important causes of skin infections. The incidence of Methicillin-resistant SA (MRSA) strains isolated from skin and skin structure infections was about 20-40%. In deep-seated pyoderma such as furuncle and furunculosis, MRSA was more frequently isolated than in other type of infectious diseases of the skin. But the incidence was gradually increasing. As to coagulase typing, type IV was most frequently isolated in MRSA. The damaged skin is easily colonized by high numbers of SA on its surface and within hair follicles. Through the indwelling catheters or decubitus SA on the skin could cause easily severe systemic MRSA infections such as sepsis or endocarditis of in-patients.
