How sequencing technology shapes our understanding of river water microbiomes and resistomes: a comparative study.

ABSTRACT: River ecosystems are vital for supporting biodiversity and supplying freshwater, but are increasingly impacted by microbial pollution, including the spread of antibiotic resistance genes (ARGs), which poses growing public health concerns. While high-throughput sequencing technologies have advanced our ability to study microbial communities and resistomes, their varying capabilities and biases require comparative analysis. In this study, we compared three sequencing approaches-Illumina 16S rRNA amplicon, Illumina shotgun metagenomics, and Oxford Nanopore-based long-read metagenomics-to profile microbial communities, ARGs, and virulence factors (VFs) in 48 river water samples. All methods identified Proteobacteria and Actinobacteria as dominant phyla, but substantial differences emerged at f
