Abstract

Background: Bacterial infections of the skin are treatable and reversible, so clinicians should be alert for the cutaneous signs of the skin infection. However, there have been only a few reports about the epidemiology of skin infections.
Objective: This study was done to evaluate the trend of the clinical features, the results of cultures and the prevalence of MRSA in the dermatology outpatients who had suspected bacterial skin infection in 1996, 2001 and 2006 and we wanted to compare the trends of bacterial skin infection over the last eleven years.
Methods: The survey was conducted via the medical records of 24 patients in 1996, 77 patients in 2001 and 88 patients in 2006 who visited the our dermatology department and who underwent Gram-stain and bacterial culture.
Results: Of the 347 samples, bacteria were cultured in 197 samples. Among them, 77 samples had coagulase negative Staphylococci, which were excluded as normal skin flora. Among 120 samples, the number of cases of secondary pyoderma, folliculitis, furuncle or carbuncle and cellulitis were 63, 17, 17 and 15, respectively. There was no change in the type of diagnosis during eleven years. The most common pathogen of skin infection was S. aureus (42.7%) and there was no trend to increase for ten years. However, the prevalence of methicillin resistant S. aureus (MRSA) increased for eleven years.
Conclusion: The most common pathogen in pyogenic skin infections of the dermatology outpatients was S. aureus, which was sensitive to β-lactamase resistant β-lactam antibiotics, but there was an increase of the prevalence of MRSA for eleven years, and the first therapeutic choice for MRSA is vancomycin or teicoplanin.
