Background: Laboratory coats are known to act as vectors in the transport of multidrug-resistant microorganisms. This study was carried out to investigate the site, and microbial antibiotic susceptibility that exist on of health care professionals white coats engaged in doing endodontic treatment to assess the risk of pathogenic microorganisms transmission.
Aim: The study was done to detect Bacterial contamination on white coats for medical students at Azadi Teaching Hospital /Duhok.
Materials and Method: A total of 50 lab coats of Medical female Students were included in the study. Sample was collected from mouth pockets of white coat. Moisten sterile swabs with normal saline were used, then inoculated into nutrient broth at 37°C/24hr, after that sub-cultured on agar media like: Nutrient agar, MacConkey agar, Mannitol salt agar, and Blood base agar. Bacterial identification were done depending on colonies features, Gram stain, followed by biochemical tests.
Results: Fifty Lab coats were examined for the presence of bacteria, which owned and used by medical female students. All of the examined Lab coats (100%) were contaminated microorganisms. Four bacterial isolates were found, including: (56%) Coagulase negative Staphylococci (CoNS), Staphylococcus aureus (40%), Bacillus spp., (30 %), and (10 %) E. coli.
Conclusion: White coats are a potential source of cross-infection that contain bacterial agents and can play a large role in the transmission of bacterial infection among medical students.
