The plasmid encodes a Type III secretion system (T3SS) on a 30 kb pathogenicity island (PAI), and is maintained in a bacterial population through a series of toxin:antitoxin (TA) systems which mediate post-segregational killing (PSK). (ox.ac.uk)

During growth at environmental temperatures, we show for the first time that pINV spontaneously integrates into different sites in the chromosome, and this is mediated by inter-molecular events involving IS1294. (ox.ac.uk)

BackgroundCampylobacter jejuni is the leading bacterial cause of human gastroenteritis in the developed world. (omictools.com)

Abstract: Bacterial whole genome sequence (WGS) methods are rapidly overtaking classical sequence analysis. (unican.es)
The whole genome of bacterial DNA was sequenced by whole genome sequencing (WGS) method.Based on Illumina NovaSeq and PacBio SequeI sequencing platforms,the whole genome sequencing results were analyzed by gene function annotation and bioinformatics analysis (including basic genome information,functional element analysis and subsystem analysis,etc. (chvm.net)

There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water . (alchetron.com)
There are approximately ten times as many bacterial cells in the human microbiota as there are human cells in the body, with their largest number being in the gut flora, and a large number on the skin . (alchetron.com)
the bacterial DNA doubles in quantity, divides into two, and the bacterial cell elongates and splits into two identical daughter cells. (atarsurvivalguide.com)
It is used to select for cells that has successfully taken up plasmid for the purpose of expression of inserted DNA. (biotechfront.com)
Among 22 tested compounds six block E-cadherin cleavage by HtrA in vitro and result in reduced scattering and wound healing of gastric epithelial cells, thereby preventing bacterial infiltration of the epithelium. (uni-frankfurt.de)
