Abstract:
Objective To investigate the changing patterns of Staphylococcus aureus (SA) and its resistance from a paediatric clinic in Beijing Children's Hospital Affiliated to Capital University of Medical Sciences.Methods SA isolated from hospitalized patients in Beijing Children's Hospital Affiliated to Capital University of Medical Sciences from Jan.2003 to Dec.2012 were analyzed.Antimierobial susceptibility was determined by disk diffusion method and Phoenix 100 microbiological system.Results were analyzed according to the 2012 guidelines of Clinical and Laboratory Standard Institute.WHONET 5.6 software was used to analyze the data.Results The clinical isolates of SA from inpatient were 2 843.The positive rates of SA were 10.0%,8.7%,9.0%,11.6%,12.7%,11.7%,10.5%,10.8%,11.9% and 11.7% form 2003 to 2012,respectively.The positive rate of Methicillin-resistant Staphylococcus aureus (MRSA) from inpatients was 10.9%.The positive rates of MRSA were 3.1%,5.4%,6.4%,4.1%,6.0%,10.6%,11.2%,12.7%,14.1% aid 20.1% form 2003 to 2012,respectively.The resistant rate of Methicillin-susceptible Staphylococcus aueus and MRSA to Penicillin were 91.4% and 100.0%,Oxacillin were 0 and 100.0%,Cefuroxime were 0.5% and 87.7%,Ceftriaxone were 0.1% and 90.3%,Amoxicillin-clavulanic acid were 0.9% and 86.7%,Erythromycin were 72.4% and 92.2%,Clindamycin were 50.6% and 80.3%,Ciprofloxacin were 2.2% and 30.1%,Trimethoprim-sulfamthhoxazol were 12.2% and 13.9%.Vancomycin-intermediate and Vancormycin-resistant Staphylococcus aureus were not found.Conclusions The prevalence of MRSA is increasing in paediatric inpatients.And MRSA isolates exhibit multidrug resistance.The sequential surveillance about SA is very important for guiding rational antimicrobial therapy and effective control of infections in paediatric patients.
