Abstract EN
Nasal carriage of Staphylococcus aureus (S.
aureus) probably causes the transmission of infection between individuals in hospital and community.
This study aimed to evaluate the molecular epidemiology and antibiotic resistance pattern of nasal carriage S.
aureus in pediatric ward patients and personnel.
A total of 122 Nasal samples were taken from 28 personnel and 94 hospitalized patients in the pediatric ward.
Minimum Inhibitory Concentration (MIC) to vancomycin and cefoxitin was determined by Agar dilution method strips.
All S.
aureus isolates were analyzed by pulsed-field gel electrophoresis (PFGE).
A total of 41 S.
aureus were isolated from the patients.
16 isolates (39.09%) were hospital-associated S.
aureus (HA-SA) and 25 (60.97%) were communityassociated S.
aureus (CA-SA); also, 13 S.
aureus isolates were obtained from the personnel.
Based on MIC results, all of S.
aureus isolates were susceptible to vancomycin, and in 41 patient isolates, 13 isolates (31.7%) were resistant to cefoxitin (MRSA).
Of 13 S.
aureus isolates of the personnel, 3 (23%) isolates were MRSA.
Totally 11 common clones and 13 single clones were obtained.
In conclusion the prevalence of CA-SA in the ward was higher than that of HA-SA.
In the strains obtained from a hospital ward, there was a high epidemiology, genotypic diversity in the studied ward.
However, horizontal transfer of S.
aureus was observed between patients and between personnel and patients, which indicated the risk of transmission of resistant strains in the hospital wards
