Bacteria have numerous distinctive groups of phage–plasmids with conserved phage and variable plasmid gene repertoires

open access: yesNucleic Acids Research, 2021
Plasmids and temperate phages are key contributors to bacterial evolution. They are usually regarded as very distinct. However, some elements, termed phage–plasmids, are known to be both plasmids and phages, e.g. P1, N15 or SSU5. The number, distribution,

Pan-Genome Portrait of Bacillus mycoides Provides Insights into the Species Ecology and Evolution

open access: yesMicrobiology Spectrum, 2021
Bacillus mycoides is poorly known despite its frequent occurrence in a wide variety of environments. To provide direct insight into its ecology and evolutionary history, a comparative investigation of the species pan-genome and the functional gene ...

Characterizing Plasmids in Bacteria Species Relevant to Urinary Health

open access: yesMicrobiology Spectrum, 2021
The urinary tract has a microbial community (the urinary microbiota or urobiota) that has been associated with human health. Whole genome sequencing of bacteria is a powerful tool, allowing investigation of the genomic content of the urobiota, also ...

PixR, a Novel Activator of Conjugative Transfer of IncX4 Resistance Plasmids, Mitigates the Fitness Cost of mcr-1 Carriage in Escherichia coli

open access: yesmBio, 2022
The emergence of the plasmid-borne colistin resistance gene mcr-1 threatens public health. IncX4-type plasmids are one of the most epidemiologically successful vehicles for spreading mcr-1 worldwide.

Plasmid Transfer in the Ocean – A Case Study from the Roseobacter Group

open access: yesFrontiers in Microbiology, 2017
Plasmid mediated horizontal gene transfer (HGT) has been speculated to be one of the prime mechanisms for the adaptation of roseobacters (Rhodobacteraceae) to their ecological niches in the marine habitat.

Replicon-Based Typing of IncI-Complex Plasmids, and Comparative Genomics Analysis of IncIγ/K1 Plasmids

open access: yesFrontiers in Microbiology, 2019
IncI-complex plasmids can be divided into seven subgroups IncI1, IncI2, IncIγ, IncB/O, IncK1, IncK2, and IncZ. In this study, a replicon-based scheme was proposed for typing IncI-complex plasmids into four separately clustering subgroups IncI2, IncI1/B/O,

Pathways for horizontal gene transfer in bacteria revealed by a global map of their plasmids

open access: yesNature Communications, 2020
Plasmids can mediate horizontal gene transfer of antibiotic resistance, virulence genes, and other adaptive factors across bacterial populations. Here, we analyze genomic composition and pairwise sequence identity for over 10,000 reference plasmids to ...

Transfer of Carbapenem-Resistant Plasmid from Klebsiella pneumoniae ST258 to Escherichia coli in Patient

open access: yesEmerging Infectious Diseases, 2010
Klebsiella pneumoniae carbapenemase (KPC) 3–producing Escherichia coli was isolated from a carrier of KPC-3–producing K. pneumoniae. The KPC-3 plasmid was identical in isolates of both species. The patient's gut flora contained a carbapenem-susceptible E.

Efficient in vitro synthesis of biologically active RNA and RNA hybridization probes from plasmids containing a bacteriophage SP6 promoter.

open access: yesNucleic Acids Research, 1984
A simple and efficient method for synthesizing pure single stranded RNAs of virtually any structure is described. This in vitro transcription system is based on the unusually specific RNA synthesis by bacteriophage SP6 RNA polymerase which initiates ...

The Importance of the Expendable: Toxin–Antitoxin Genes in Plasmids and Chromosomes

open access: yesFrontiers in Microbiology, 2017
Toxin–antitoxin (TA) genes were first reported in plasmids and were considered expendable genetic cassettes involved in the stable maintenance of the plasmid replicon by interfering with growth and/or viability of bacteria in which the plasmid was lost ...
