Objective To investigate the molecular characteristic of Community-acquired Methicillin-resistant Staphylococcus aureus(CA-MRSA) isolates from pediatric patients in Guangzhou. Methods 65 non-duplicate strains of Community-acquired Methicillin-susceptible Staphylococcus aureus(CA-MSSA) isolated from our hospital in 2009-2014 were investigated. Panton-valentine leukocidin(PVL) gene was detected by polymerase chain reaction(PCR). The sequence type (ST) of each strain was determined by muhilocus sequence typing (MLST). The genotypes of staphylococcal cassette chromosome mec(SCCmec) of the CA-MRSA isolates were confirmed by multiplex PCR. Results Among 65 isolates of CA-MRSA, the positive rate of PVL genes was 47.69%(31／65). The most common MLST type was ST59 (n=22, 33.84%), followed by ST88 (n=15, 23.07%). Three SCCmec types were found. The most common type was SCCmecIV (49.23%, 32/65), followed by SCCmecⅡ (32.30%, 21/65) and SCCmecV (8.46%, 12/65). Conclusion The PVL gene-positive rate of CA-MRSA isolates in our hospitals is at a relatively high level. SCCmec type IV and SCCmec type V could spread among hospitals and cause a small scale epidemic. Their phenotypes have a variety of ST types.
