Abstract

Objective: Microorganisms ping pong effect from hand to cell phone can actualize. The aim of this study was to investigate the bacterial diversity and to compare the similarities of bacteria of the thumb, forefinger cultures and smart phones surface swab cultures taken from the Baskent University Faculty of Medicine students. We also targeted that to compare bacterial disparity of clinical and preclinial students and to see the affect of hand washing, cell phone cleaning practice on bacterial variability.
Methods: after voluntary informed consent forms were signed, students from Baskent University Faculty of Medicine were included to the study. Finger cultures were taken from thumb, forefinger of their active hands. Swab cultures collected from surface of the smart phones. Identifications of isolated colonies were performed with conventional methods.
Results: Smartphone and finger cultures were collected from total 230 subjects, including 143 women 87 men's. 65% of cultures were taken from preclinical student and the rest from clinical students. Bacterial similarity was recovered from finger cultures and Smartphone cultures in 79% of volunteers (p<0.001).
Conclusion: Our study was revealed that hand cleaning was affecting bacterial diversity and the frequency of hand washing influenced the bacterial variety. Although we expected to find a significant difference for bacterial diversity between preclinical and clinical students, our study did not confirm this opinion.
