A retrospective review of the medical records of 25 patients with SSSS between July 2010 and October 2014 was conducted. The clinical characteristics of patients were collected and the antibiotic susceptibility of S. aureus were analyzed using automated systems.
RESULTS:
The median age of the patients was 22 months (range 2–95). Ninety-two percent of patients were less than 5 years of age. Nasal swab samples of all patients and skin swab samples of 17 patients were cultured to isolate S. aureus. Twenty-one (84%) of 25 patients were colonized with methicillin-resistant S. aureus (MRSA). The results of swab samples of the other four patients were no growth or isolation of bacteria other than S. aureus. Among 20 strains isolated from the anterior nares, 1 strain (5%) was methicillin-susceptible S. aureus. All 15 strains isolated from the skin were MRSA. All 21 strains isolated from anterior nares or skin were found to be resistant to clindamycin upon evaluation using automated systems.
