Nasal carrier state of Methicillin resistant staphylococcus aureus (MRSA) in healthy medical students in a tertiary care hospital

Abstract

Introduction: As Staphylococcus aureus, important nosocomial pathogen, normally present in the nasal cavity of healthy individuals, can be transmitted to the patients during routine patients care by the health care workers. Objective: To assess the nasal carrier state of Methicillin Resistant Staphylococcus aureus (MRSA) in healthy Medical students. Methodology: Nasal swabs were collected from the anterior nares of eighty seven medical students. Bacterial isolation and identification were carried out using standard microbiological methods. Resistance to Methicillin was determined using Methicillin Resistant Selective agar (MeReSa Agar) and compared with standard susceptibility to Cefoxitin disc on Mueller Hinton agar. Results: Among the 87 medical students, 34 (39.1%) were found to be colonized with Staphylococcus aureus in their anterior nares. Nasal carrier rate of MRSA among medical students was found to be 33.33%. Methicillin was detected in 29 Staphylococcus aureus isolates by screening in MeReSa agar. Concordant results were obtained with Cefoxitin resistance on routine Disc diffusion testing. All the Staphylococcus aureus were susceptible to Vancomycin. Conclusion: It’s worrisome that the present study reports an alarmingly high prevalence of MRSA nasal colonization (33.33%) among the medical students. This heaves a serious concern about the possibility of transmission of MRSA from the medical students to the patients and hospital staff during their clinical postings.
