Salmonella enterica és un patogen entèric primari que infecta tant humans com animals i és
la causa més freqüent de malalties transmeses per aliments. S. enterica es pot propagar a …

Salmonella enterica is the most frequently reported cause of foodborne illness. As in other
microorganisms, chemotaxis affords key physiological benefits, including enhanced access …

The RecA protein is the main bacterial recombinase and the activator of the SOS system. In
Escherichia coli and Salmonella enterica sv. Typhimurium, RecA is also essential for …

Swarming, a flagellar-driven multicellular form of motility, is associated with bacterial
virulence and increased antibiotic resistance. In this work we demonstrate that activation of …

Escherichia coli and Salmonella enterica are models for many experiments in molecular
biology including chemotaxis, and most of the results obtained with one organism have …

In addition to its role in DNA damage repair and recombination, the RecA protein, through its
interaction with CheW, is involved in swarming motility, a form of flagella-dependent …

M otile bacteria move with purpose: their movement machinery, whether for swimming or
gliding, is responsive to environmental cues and enables them to seek optimal living …

Acinetobacter baumannii is a nosocomial pathogen that causes multi-drug resistant
infections mainly in immunocompromised patients. Although this gram-negative species …

In Escherichia coli, chemoreceptor clustering at a cell pole seems critical for signal
amplification and adaptation. However, little is known about the mechanism of localization …

The chemosensory behavior of bacteria is the signal transduction system that is best
understood at the molecular level. A good part of the reason for that status is the …
