Fitness Costs of Plasmids: a Limit to Plasmid Transmission [PDF]

open access: yesMicrobiology Spectrum, 2017
ABSTRACT Plasmids mediate the horizontal transmission of genetic information between bacteria, facilitating their adaptation to multiple environmental conditions. An especially important example of the ability of plasmids to catalyze bacterial adaptation and evolution is their instrumental role in the global spread of antibiotic resistance ...

Plasmid persistence: costs, benefits, and the plasmid paradox [PDF]

open access: yesCanadian Journal of Microbiology, 2018
Plasmids are extrachromosomal DNA elements that can be found throughout bacteria, as well as in other domains of life. Nonetheless, the evolutionary processes underlying the persistence of plasmids are incompletely understood. Bacterial plasmids may encode genes for traits that are sometimes beneficial to their hosts, such as antimicrobial resistance,

Variability of plasmid fitness effects contributes to plasmid persistence in bacterial communities

open access: yesNature Communications, 2021
Plasmid persistence in bacterial populations is strongly influenced by the fitness effects associated with plasmid carriage. However, plasmid fitness effects in wild-type bacterial hosts remain largely unexplored. In this study, we determined the fitness

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,

Antimicrobial resistance of Salmonella Indiana from retail chickens in China and emergence of an mcr-1-harboring isolate with concurrent resistance to ciprofloxacin, cefotaxime, and colistin

open access: yesFrontiers in Microbiology, 2022
Salmonella enterica serotype Indiana (S. Indiana) in Chinese poultry meat has aroused widespread concern because of its high prevalence and strong antimicrobial resistance. In consideration of the relationship in our previous study between S. Indiana and

Distribution and Transmission of Colistin Resistance Genes mcr-1 and mcr-3 among Nontyphoidal Salmonella Isolates in China from 2011 to 2020

open access: yesMicrobiology Spectrum, 2023
Mobile colistin resistance (mcr) genes are present mainly in plasmids and can disseminate clonally or horizontally via either plasmids or insertion sequences in different genomic locations among the Enterobacteriaceae.

Detection of an IMI-2 carbapenemase-producing Enterobacter asburiae at a Swedish feed mill

open access: yesFrontiers in Microbiology, 2022
Occurrence of multidrug resistant Enterobacteriaceae in livestock is of concern as they can spread to humans. A potential introduction route for these bacteria to livestock could be animal feed.

DNA Minicircle Technology Improves Purity of Adeno-associated Viral Vector Preparations

open access: yesMolecular Therapy: Nucleic Acids, 2016
Adeno-associated viral (AAV) vectors are considered as one of the most promising delivery systems in human gene therapy. In addition, AAV vectors are frequently applied tools in preclinical and basic research. Despite this success, manufacturing pure AAV

Molecular Characterization of blaNDM-Carrying IncX3 Plasmids: blaNDM-16b Likely Emerged from a Mutation of blaNDM-5 on IncX3 Plasmid

open access: yesMicrobiology Spectrum, 2022
Dissemination of blaNDM, which is carried on the IncX3 plasmid, among Enterobacterales has been reported worldwide. In particular, blaNDM-5-carrying IncX3 plasmids can spread among several hosts, facilitating their dissemination.

A rapid alkaline extraction procedure for screening recombinant plasmid DNA.

open access: yesNucleic Acids Research, 1979
A procedure for extracting plasmid DNA from bacterial cells is described. The method is simple enough to permit the analysis by gel electrophoresis of 100 or more clones per day yet yields plasmid DNA which is pure enough to be digestible by restriction ...
