It is demonstrated that deletion of arlR significantly reduces the tolerance of the foodborne strain RMSA49 to acetic acid, desiccation, whereas its responses to temperature and osmotic stress not affected, and that the arlR mutant also exhibits significantly enhanced biofilm formation.

Significance In the pathogen Acinetobacter baumannii, the posttranscriptional regulator CsrA is required for growth under certain environmental conditions, including rich growth media and infection-relevant conditions like human serum. However, CsrA is dispensable for A. baumannii grown under nutrient limited condition...

During infection, Klebsiella pneumoniae must withstand host-derived oxidative stress not only by detoxifying reactive oxygen species (ROS) but also by repairing oxidative damage to cellular physiology. How these detoxification and stress-adaptive responses are coordinated remains unclear. Here, we identify a plasmid-en...

GltC contributes to the coordination of nitrogen metabolism, oxidative stress adaptation, and bacterial fitness during L. monocytogenes infection, which is critical for identifying new strategies to limit bacterial survival in the host.

Multicellular organisms require a correct microbiota composition for optimal health and fitness. Dysbiosis could lead to serious health consequences in humans and plants, and is pervasive during pathogen infections across systems. A recent study shows that carbon source availability plays a role in bacterial community...

Abstract Small regulatory RNAs (sRNAs) are key drivers of bacterial adaptation to environmental fluctuations, including iron and manganese restriction imposed by the host. This study explored the repertoire of sRNAs produced by the human pathogen Staphylococcus aureus in response to metal limitation. Two sRNAs were ide...
