Sensitivity of Staphylococcus aureus Isolated from Nasal and Throat of Pre-Clerkship Students to Antibiotics

Abstract

Clerkship students potentially transmit CA-MRSA bacteria to patients, so it is necessary to do early detection and appropriate treatment to prevent transmission. The research objective was to determine the sensitivity pattern of Staphyllococcus aureus nasal and throat swabs isolated from students to antibiotics. This research is descriptive-analytic with nasal and throat swab samples of healthy students. Each sample was obtained 60 nose and 60 throat swabs. The identification of S. aureus was carried out by macroscopic, gram staining, catalase test, and MSA test. Sensitivity pattern test using the Kirby-Bauer method. Statistical analysis using the Mann-Whitney. The result shows that S. aureus isolated from nasal swabs was 23.3% and throat by 10%. The positive prevalence of MRSA carriers was 1.7%. All isolates were sensitive to Methicillin, Vancomycin, Imipenem, Ofloxacin, and Ciprofloxacin, and were resistant to Penicillin. There was no difference between the number of S. aureus isolates from nose and throat swabs (p> 0.05). It was concluded that S. aureus was more common in nasal than in the throat isolate. The positive prevalence of MRSA carriers among students is 1.7%. All isolates sensitive to Methicillin, Vancomycin, Imipenem, Ofloxacin, and Ciprofloxacin but were resistant to Penicillin.
