Native Plasmid-Encoded Mercury Resistance Genes Are Functional and Demonstrate Natural Transformation in Environmental Bacterial Isolates [PDF]
mSystems, 2019 Plasmid-mediated horizontal gene transfer (HGT) is a major driver of genetic diversity in bacteria. We experimentally validated the function of a putative mercury resistance operon present on an abundant 8-kbp native plasmid found in groundwater samples ...

Modeling sRNA-regulated Plasmid Maintenance [PDF]
, 2016 We study a theoretical model for the toxin-antitoxin (hok/sok) mechanism for plasmid maintenance in bacteria. Toxin-antitoxin systems enforce the maintenance of a plasmid through post-segregational killing of cells that have lost the plasmid.

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

Identification of novel clostridium perfringens type E strains that carry an iota toxin plasmid with a functional enterotoxin gene [PDF]
, 2011 Clostridium perfringens enterotoxin (CPE) is a major virulence factor for human gastrointestinal diseases, such as food poisoning and antibiotic associated diarrhea. The CPE-encoding gene (cpe) can be chromosomal or plasmid-borne.

Microbiology and Molecular Biology Reviews, 2010 SUMMARYPlasmids are key vectors of horizontal gene transfer and essential genetic engineering tools. They code for genes involved in many aspects of microbial biology, including detoxication, virulence, ecological interactions, and antibiotic resistance.

Plasmid, 2023 Plasmids are universally present in bacteria and play key roles in the dissemination of genes such as antibiotic resistance determinants. Major concepts in Plasmid Biology derive from the efforts to classify plasmids. Here, we review the main plasmid classification systems, starting by phenotype-based methods, such as fertility inhibition and ...

Plasmid-to-plasmid recombination in Haemophilus influenzae [PDF]
Journal of Bacteriology, 1986 No recombination between plasmids was observed after conjugal transfer of a plasmid into a cell carrying another plasmid. Two types of such recombination took place after transformation, one type being Rec+ dependent and suggesting a preferred site of recombination. The other much rarer type was at least partially Rec+ independent.

Microbiology 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
Frontiers 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.
