However, the inability of short-read high-throughput sequencing methods to reliably assemble plasmids makes it difficult to investigate the diversity of plasmid structures and functions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this work, we used the long-read Nanopore sequencing method to address this issue, by producing high quality whole genome sequences of 33 bacterial strains from 11 perianal abscess-suffering patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results and discussion<\/jats:title><jats:p>Successful high quality assemblies were generated with this method, including 20 perfect assemblies out of 33 genomes. A total of 47 plasmids were identified from the bacterial strains, including 12 unique, newly identified, high quality circular plasmids. These plasmids were further subject to structural analysis, leading to the finding of significant diversification from previously known plasmids, suggesting the diversity of plasmid structure and function. Particularly, two <jats:italic>mcr-10.1<\/jats:italic>-harboring conjugative plasmids were found from <jats:italic>Citrobacter portucalensis<\/jats:italic> and <jats:italic>Enterobacter kobei<\/jats:italic>, which were not previously reported.
