Table 3 Analysis of published metagenomic data for foreign plasmids. In all analyzed metagenomics studies albeit not in all of the samples, plasmid sequences were found. The same plasmid sequences found in the metagenomic data set of J.R. Bedarf et al. and M. Thoendel et al., were Bacteroides fragilis IB143 (ENA ID: U30316.1), tetracyclin-coding resistance of Bifidobacterium longum B200304 pBIF10 (ENA ID: DQ093580.1) and Xuhuaishuia manganoxidans strain DY6-4 plasmid (ENA ID: CP019124.1). Unique plasmid sequences found for J. R. Bedarf et al., were Streptococcus parasanguinis plasmid pFW213 (Accession: NC_012642.1), Escherichia coli plasmid pCM959 (ENA ID: K00826.1) Bacteroides thetaiotaomicron VPI-5482 plasmid p5482 (ENA ID: GCA_000011065.1), Escherichia coli strain D1 plasmid A (ENA ID: CP010134.1), Escherichia coli strain MDR_56 plasmid unnamed 5 (ENA ID: CP019906.1), Eubacterium eligens ATCC 27750 plasmid (ENA ID: 515620) and Pseudomonas chlororaphis strain PCL1606 plasmid (ENA ID: CP011110.1) as well as Staphylococcus epidermidis plasmid SAP108D (ENA ID: GQ900461.2) for M. Thoendel et al. In the sequences of J. Law et al., although using unspecific pre-amplification with different MDA Kits only Acinetobacter pittii strain AP_882 plasmid pNDM-AP_882 (ENA ID: CP014477.1), Acinetobacter soli strain GFJ2 plasmid pGFJ6 and pGFJ7 (ENA: CP016902.1) were found.
