“…The nasal carriage rate of MRSA in international studies in students ranged from 0% -6.7%. 3,[9][10][11]14 Amongst the Indian studies, a study by Bhaskaran reported a MRSA colonization of 8.6% among medical students while another study by Shrivastav et al 2015 reported the MRSA carriage rate to be 1.1%, which is much lower than our study. 6,15 The present study showed no significant difference in carriage rate of S.aureus and MRSA among male and female students.…”

Background: Staphylococcus aureus is a dynamic and adaptable bacterium that has an incredible talent to attain antibiotic resistance. Nasal colonisation of S.aureus increases with greater exposure of students to the hospital environment. The prevention of staphylococcal infection and reduction of spread and emergence of MRSA are essential. Medical students would be a key target group to introduce awareness of hospital-acquired infections. Therefore, the present study aims at understanding the prevalence of carrier rate of S.aureus and MRSA among Medical students during their clinical postings.Methods: Nasal swabs were taken from 150 medical students. Their Staphylococcus aureus nasal carriage was determined by plating on sheep blood agar and MRSA carriage by to Kirby Bauer Disc Diffusion method using Cefoxitin disc (30 µg).Results: The present study showed a 40% nasal carriage of S.aureus amongst medical students. Of the 60 S. aureus isolates 28%, 36% and 56% isolates were from 1st, 2nd and 3rd year respectively. The colonisation rate of MRSA in the present study was found to be 12.66% amongst the medical students of 6%, 10%, 22% belonged to 1st, 2nd, and 3rd respectivelyConclusions: The nasal carriage of Staphylococcus aureus and methicillin resistant Staphylococcus aureus (MRSA) among medical students increases as their exposure to patient care increases. Medical students should be made aware of the risks of carrying S.aureus and MRSA and educated about the hand washing protocol and safety precautions to be followed while handling patients.

“…The study also showed that S. aureus carriage rate was higher in clinical than non-clinical students. [11] However, our study showed that there was no association of S. aureus carriage between preclinical and clinical groups. A survey conducted on a 95 college students in Hawaii for the nasal carriage of S. aureus revealed 33% positive, out of which 3 (3.15%) were MRSA.…”

Background: 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.

“…The differences in the study design such as the sample size and the method employed for S. aureus and MRSA detection may account for the disparity in the carriage rate [4,17]. Nasal carriage of S. aureus among Internees of Kasturba Medical College, Mangalore, India, according to the result of this study was 47.3%.…”

Objective: The incidence of community-acquired and hospital-acquired Staphylococcus aureus infections has been rising with increasing emergence of drug-resistant strains called methicillin-resistant S. aureus (MRSA). The main objective of this study was to determine the prevalence of carriage rate of MRSA among the interns of tertiary care teaching hospital in Mangalore.Methods: A total of 150 interns were participated, thereby swabs from both anterior nares were collected and processed for S. aureus. The isolated strains of S. aureus were screened for methicillin susceptibility by modified Kirby-Bauer method using cefoxitin (30 µg) disc. Further, antibiotic susceptibility testing for all isolates of S. aureus was also done against selected appropriate antibiotics. Vancomycin susceptibility testing for MRSA was done by E test. Results:The number of strains of S. aureus isolated from our 150 participants was 71 with a percentage rate of 47.3. Of the 71 isolates of S. aureus, one (1.4%) was MRSA. The overall MRSA carriage rate was 0.66%. The S. aureus and MRSA carriage rates recorded in this study were at par and significantly lower, respectively, when compared with other reported studies. It was observed that risk factors such as the use of antibiotics in the past 6 months and smoking were found to be statistically significant in nasal carriage status of S. aureus (<0.05). The only one isolate of MRSA was found to be sensitive to vancomycin, linezolid, and teicoplanin. Conclusion:It was concluded that the acquisition of S. aureus and MRSA would not be an occupational hazard for medical students of developing countries like India.
