Monitoring Cross-Border Dissemination of Antimicrobial Resistance (AMR) via Air Travel to Saudi Arabia: Formulation of Monitoring Strategies to Mitigate AMR Concerns

High Resolution Image Download MS PowerPoint Slide Antimicrobial resistance (AMR) is a global health challenge, and its dissemination can be accelerated by international air travel. Aircraft sewage, aggregating microbial material from global travelers, offers a unique surveillance opportunity for AMR at international entry points. However, specific AMR elements detected in aircraft sewage and how their relative abundance and transcriptional activity may be associated with flight characteristics such as flight duration or departure country remain unclear. This study analyzed 130 sewage samples from international flights arriving in Saudi Arabia across 27 countries. Metagenomic analyses revealed distinct AMR profiles in aircraft sewage compared to local municipal sewage, including elevated relative abundances of Enterococcus faecium and Staphylococcus aureus . Aircraft sewage harbored 51 …
