Hospital-Associated Antimicrobial Resistant Bacteria on 95 Mobile Phones: An International Metagenomic "Phonome"...

Antimicrobial resistant healthcare-associated infections present an increasing threat to public safety and the sustainability of healthcare systems around the world. Mobile phones have been highlighted as a fomite that negates hand hygiene and contributes to the dissemination of pathogenic microorganisms in healthcare settings. The objective of the current stidy was to investigate the presence of bacteria, antimicrobial resistance and virulence genes associated with high morbidity on 95 mobile phones within healthcare settings. Next-Generation Metagenomic Sequencing was undertaken and FastQ files were subsequently analyzed within COSMOSid to enable taxonomic identification. Antibiotic resistant genes, virulence genes and bacteriophages were co-located with bacteria associated with the highest global mortality. Antibiotic resistant genes were manually annotated and cross referenced with the Comprehensive Antibiotic Resistance Database (CARD) to identify gene-drug interactions. On average, mobile phones were identified to be contaminated with 3.62 of the top 10 highest mortality-causing bacteria and 2.49 ESKAPE pathogens. A total of 262 unique ARGs, 448 unique VFGs, and 314 bacteriophages were identified. Mobile phones within healthcare settings harbor pathogens alongside genes associated with increased virulence and antimicrobial resistance. Additionally, mobile phones, known to be infrequently sanitized, may increase antimicrobial resistance by providing a contaminated platform which facilitates continued horizontal genetic transfer.
