Plasmid incompatibility.
A bacterial plasmid is a species of nonessential extrachromosomal deoxyribonucleic acid (DNA) that replicates autonomously as a stable component of the cell's genome. Naturally occurring plasmids range in size from one to several hundred kilobases and in copy number from one to several hundred per cell. Copy number is a fixed characteristic of any plasmid under constant conditions and is contro...
متن کاملCuring of Plasmid pXO1 from Bacillus anthracis Using Plasmid Incompatibility
The large plasmid pXO1 encoding the anthrax toxin is important for the virulence of Bacillus anthracis. It is essential to cure pXO1 from B. anthracis to evaluate its role in the pathogenesis of anthrax infection. Because conventional methods for curing plasmids (e.g., curing agents or growth at elevated temperatures) can induce mutations in the host chromosomal DNA, we developed a specific and...
متن کاملRule-based modelling of conjugative plasmid transfer and incompatibility
COSMIC-rules, an individual-based model for bacterial adaptation and evolution, has been used to study virtual transmission of plasmids within bacterial populations, in an environment varying between supportive and inhibitory. The simulations demonstrate spread of antibiotic resistance (R) plasmids, both compatible and incompatible, by the bacterial gene transfer process of conjugation. This pa...
متن کاملStructure and regulation of gene expression of a Clo DF13 plasmid DNA region involved in plasmid segregation and incompatibility.
The bacteriocinogenic plasmid Clo DF13 contains genetic information involved in the accurate partitioning of the plasmid (parA and parB) as well as in incompatibility phenomena (incA, B, C and D). In this paper we report on the primary structure and regulation of gene expression of the 29% - 50% part of Clo DF13, containing the DNA regions incA, incB and parB as well as genes K and L. According...
