    Abstract:
    AIM: To investigate the characteristic of community-associated methicillin-resistant staphylococcus aureus (CA-MRSA) skin and soft tissue infections (SSTIs) among children in China. METHODS: Forty-seven children with CA-MRSA SSTIs were enrolled in this study. Clinical information was collected and analysed. The strains from the children were analysed by multilocus sequence typing (MLST), staphylococcus cassette chromosome mec (SCCmec) typing and spa typing. The Panton-Valentine leukocidin (PVL) gene was also detected. RESULTS: The majority of the 47 cases were impetigo (20; 42.6%) and abscesses (14; 29.8%). The rest was cellulites, infected wounds, omphalitis, paronychia and conjunctivitis combined folliculitis. Thirty-two of the isolates (68.1%) were PVL-positive, and the abscesses infected with PVL-positive strains usually required incision and drainage (87.5% vs. 16.7%, p = 0.026). Most of the isolates belonged to ST type 59, which accounted for 46.8%, followed by ST1 (7/47, 14.9%) and ST910 (5/47, 10.6%). The clone of ST59-MRSA-IV with t437 was the most prevalent one. The multiresistant rate of these strains was 93.6%. CONCLUSION: The most common disease of CA-MRSA SSTIs was impetigo, and PVL-positive abscess was associated with incision and drainage. ST59-MRSA-IV with t437 was the most prevalent clone, and the multiresistant rate was high in Chinese children.
