This study aimed to identify the contamination rates of clinical white coats worn by medical students with selected potential pathogens and their antibiotic resistant phenotypes.</p><p><strong>Methods:</strong> A cross-sectional study was done among 151 4th year medical students of Faculty of Medicine, University of Peradeniya, Sri Lanka in September 2020. The participants belonged to two batches undergoing clinical training at two settings. Swabs from pockets and sleeves of the clinical white coats were taken. Potential pathogens and their resistant phenotypes were identified with routine tests.</p><p><strong>Results:</strong> Fifty-three participants (35.1%) had coats contaminated with <em>Staphylococcus aureus</em>; 15 (9.9%) had coats contaminated with Methicillin-Resistant <em>S.aureus</em> (MRSA).  One <em>Enterobacterales</em> (0.7%) was an <em>AmpC</em> producer.  <em>Enterococcus</em> species were isolated from 19 (12.6%) coats and 2 (1.3%) had coats contaminated with vancomycin resistant enterococci.  Molecular testing on the MRSA isolates identified that 5(20%) of the MRSA isolates were <em>PVL</em> positive while all were <em>mecA</em> positive. Sex, type of clinical appointment, and frequency of washing white coats were not associated with contamination. The “batch” was significantly associated with contamination with <em>S.aureus</em> and <em>Enterococcus</em> species. </p><p><strong>Conclusions:</strong> We found that clinical white coats worn by medical students recruited for the study were contaminated with <em>S.aureus</em>, MRSA and <em>Enterococcus</em> species. There was a notably high-rate of contamination with <em>S. aureus.</em>  All MRSA isolates were <em>mecA</em> positive while the rate of <em>PVL</em> positivity was low.</p> ER -
