| contents | Metagenomic surveys show a widespread diffusion of antibiotic resistance genes in a transect from urbanized to marine protected area. Alonso-Vásquez, Tania Fagorzi, Camilla Mengoni, Alessio Oliva, Matteo Cavalieri, Duccio Pretti, Carlo Cangioli, Lisa Bacci, Giovanni Ugolini, Alberto Drug Resistance, Microbial Italy Metagenomics Bacteria Geologic Sediments RNA, Ribosomal, 16S Environmental Monitoring Metagenome Microbiota Urbanization Ports are hot spots of pollution; they receive pollution from land-based sources, marine traffic and port infrastructures. Marine ecosystems of nearby areas can be strongly affected by pollution from port-related activities. Here, we investigated the microbiomes present in sea floor sediments along a transect from the harbour of Livorno (Central Italy) to a nearby marine protected area. Results of 16S rRNA amplicon sequencing and metagenome assembled genomes (MAGs) analyses indicated the presence of different trends of specific bacterial groups (e.g. phyla NB1-j, Acidobacteriota and Desulfobulbales) along the transect, correlating with the measured pollution levels. Human pathogenic bacteria and antibiotic resistance genes (ARGs) were also found. These results demonstrate a pervasive impact of human port activities and highlight the importance of microbiological surveillance of marine sediments, which may constitute a reservoir of ARGs and pathogenic bacteria. |
