Bacteria have evolved many different signal transduction systems that sense signals and
generate a variety of responses. Generally, most abundant are transcriptional regulators …

Pathogens that infect the gastrointestinal and respiratory tracts are subjected to intense
pressure due to the environmental conditions of the surroundings. This pressure has led to …

Staphylococci are a versatile genus of bacteria that are capable of causing acute and
chronic infections in diverse host species. The success of staphylococci as pathogens is due …

Biofilm formation is an important mechanism of survival and persistence for many bacterial
pathogens. These multicellular communities contain subpopulations of cells that display …

Hydrogen sulfide (H2S) is thought to protect bacteria from oxidative stress, but a
comprehensive understanding of its function in bacteria is largely unexplored. In this study …

How cells regulate the bioavailability of utilizable sulfur while mitigating the effects of
hydrogen sulfide toxicity is poorly understood. CstR [C opper‐sensing operon repressor (C …

Staphylococcus aureus is a major human pathogen, which encounters reactive oxygen,
nitrogen, chlorine, electrophile and sulfur species (ROS, RNS, RCS, RES and RSS) by the …

The pathogenicity of Clostridium difficile is linked to its ability to produce two toxins: TcdA
and TcdB. The level of toxin synthesis is influenced by environmental signals, such as …

Staphylococcus aureus is the causative agent of various biofilm-associated infections in
humans causing major healthcare problems worldwide. This type of infection is inherently …

Staphylococcus aureus is a commensal human pathogen and a major cause of nosocomial
infections. As gaseous signaling molecules, endogenous hydrogen sulfide (H2S) and nitric …
