ABSTRACT
BACKGROUND: Mobile phones are excessively used even though microbes' ability to survive on phone surfaces was confirmed. During the COVID-19 pandemic, heavy hygiene practices have been applied to mobile surfaces. Therefore, it is interesting to evaluate the emergence of antimicrobial-resistant bacteria on mobile phone surfaces. METHODS: A random sampling technique was utilized on residents in Abu Dhabi, UAE between May and June 2021. A swab sample from each participant's mobile phone was collected and transported to the microbiology laboratory for bacterial culture and antimicrobial susceptibility tests. Furthermore, a cross-sectional study was conducted via a self-administered questionnaire filled by participants. The questionnaire was used to collect sociodemographic data, phone frequency usage and cleaning methods. RESULTS: One hundred two-sample swabs and data have been included in the study. The majority of participants (91.1%) reported cleaning their mobile phones with wipes and alcohol. However, 100% of participants had a mobile phone contaminated by bacteria such as S. aureus, E. coli, Coagulase-negative staphylococci, Micrococcus, Bacillus, Streptococcus, Citrobacter, Proteus, Enterococcus, klebsiella, Pseudomonas and Actinobacteria. Interestingly, most of these potentially pathogenic bacteria were found to be resistant to ampicillin, ceftazidime and cefotaxime. CONCLUSION: The continuous hand and mobile disinfectant have contributed to the emergence of resistant bacteria.
