TL;DR: Faecal swabs obtained from a random sample of 268 cows and 90 calves on 19 Lugo farms were examined for verotoxin-producing Escherichia coli (VTEC), finding VTEC on 95% of the farms.

TL;DR: The experimental results show that the mutant genotype can be predicted from the dielectrophoretic analysis of the corresponding cultures, opening the way to the development of microdevices for specific identification.

TL;DR: It is shown that the presence of DNA in preparations of copurified His-Hha and H-NS is not directly implicated in the interaction between the proteins, and a striking and previously unnoticed similarity of the Hha family of proteins to the oligomerization domain of theH-NS proteins is reported.

TL;DR: DNA-binding studies suggest that in vivo H-NS and Hha form a nucleoid-protein complex that accounts for the thermo-osmotic regulation of the hemolysin operon in E. coli.

TL;DR: Evidence is provided that H-NS discriminates and differentially modulates core and HGT DNA, which may help to maintain horizontally transmitted DNA in silent form and may give these bacteria a competitive advantage in adapting to new environments, including host colonization.
