| Summary: | Nasal carriage of Staphylococcus aureus (S.aureus) especially methicillin-resistant S. aureus (MRSA) among health care personnel poses a risk to the patient. Objectives: To determine the prevalence of nasal colonization of S. aureus and its antibiotic susceptibility pattern among pre-clinical and clinical medical and nursing students attending Faculty of Medicine and Health Sciences at the Universiti Malaysia Sabah. Materials and Methods: Between April and November 2013, nasal swabs were collected from anterior nares of 449 students and inoculated on Mannitol salt agar and Tryptone soya broth. Staphylase coagulase test kit and tube coagulase
test were done for identification. Antibiotic susceptibility test was done on seven antibiotics by Kirby–Bauer
method. S. aureus isolates which showed zone diameter of 22 mm to cefoxitin discs were further tested with
Slidex® MRSA detection kit to detect penicillin-binding protein product of MRSA. Results: The prevalence of
nasal colonization of S. aureus was 31.0% and all were methicillin susceptible S. aureus (MSSA). Antibiotic
susceptibility testing revealed all 139 S. aureus isolates were sensitive to oxacillin, trimethoprim/sulfamethoxazole
and cefoxitin, whereas 116 (83.5%), 1 (0.7%), 3 (2.2%) and 24 (17.3%) were resistant to penicillin, erythromycin,
clindamycin and tetracycline, respectively. Conclusions: There was no MRSA among S. aureus isolated in this
study. S. aureus isolates were highly resistance to penicillin, however, no resistant to oxacillin, co-trimoxazole, and cefoxitin |
