Evidence that the 36kb plasmid of Brachyspira hyodysenteriae contributes to virulence [PDF]
, 2011 Swine dysentery (SD) results from infection of the porcine large intestine with the anaerobic intestinal spirochaete Brachyspira hyodysenteriae. Recently the genome of virulent Australian B. hyodysenteriae strain WA1 was sequenced, and a 36. kilobase (kb)

Antiparallel plasmid-plasmid pairing may control P1 plasmid replication. [PDF]
Proceedings of the National Academy of Sciences, 1991 The copy number of the P1 plasmid replicon is stringently controlled, giving only one or two copies per newborn cell. Control is achieved by the action of the copy-control locus incA, which contains nine repeats of the 19-basepair binding site for the plasmid-encoded initiator protein RepA.

Noise enhanced persistence in a biochemical regulatory network with feedback control [PDF]
Phys. Rev. Lett. 100, 058105 (2008), 2007 We find that discrete noise of inhibiting (signal) molecules can greatly delay the extinction of plasmids in a plasmid replication system: a prototypical biochemical regulatory network. We calculate the probability distribution of the metastable state of the plasmids and show on this example that the reaction rate equations may fail in predicting the ...

Determination of plasmid copy number in yeast transformants by means of agarose plugs [PDF]
, 1993 The determination of plasmid copy number in Saccharomyces cerevisiaetransformants containing circular or linear plasmids is currently performed with total yeast DNA extracts obtained from cultures grown under selection.

Predictive Modeling of Non-Viral Gene Transfer [PDF]
Biotechnology and Bioengineering, Volume 105, Issue 4, 805-813,
(2010), 2010 In non-viral gene delivery, the variance of transgenic expression stems from the low number of plasmids successfully transferred. Here, we experimentally determine Lipofectamine- and PEI-mediated exogenous gene expression distributions from single cell time-lapse analysis.

Exploiting CRISPR-Cas to manipulate Enterococcus faecalis populations
eLife, 2017 CRISPR-Cas provides a barrier to horizontal gene transfer in prokaryotes. It was previously observed that functional CRISPR-Cas systems are absent from multidrug-resistant (MDR) Enterococcus faecalis, which only possess an orphan CRISPR locus, termed ...

Plasmid evolution in carbapenemase‐producing Enterobacteriaceae: a review
Annals of the New York Academy of Sciences, 2019 Carbapenem‐resistant Enterobacteriaceae (CRE) have been listed by the WHO as high‐priority pathogens owing to their high association with mortalities and morbidities.

Guidelines for the estimation and reporting of plasmid conjugation rates [PDF]
arXiv, 2023 Conjugation is a central characteristic of plasmid biology and an important mechanism of horizontal gene transfer in bacteria. However, there is little consensus on how to accurately estimate and report plasmid conjugation rates, in part due to the wide range of available methods.
