TL;DR
The data obtained allows suggesting that SsrS and CsrC small RNAs played an important role in regulation of the cell switching to formation of biofilms, and hexuronates can be used as modeling agents in clinical practice.
CsgD may act as an integrative regulatory node linking transcriptional control of biofilm formation with quorum-sensing signaling pathways in Salmonella, and changes in CsgD levels are associated with shifts in QS-linked sRNA expression and AI-2 signaling dynamics.
The functional analysis revealed that the Δpimt mutant strain shows defective motility, reduced biofilm formation, and defective invasion and intramacrophage survival, and supplementation of Δpimt mutant strain culture with reduced glutathione resulted in neutralization of ROS and rescued the defective motility and bio...
The WT and Δ Flo11 strains grew similarly under alkaline and physiological conditions, while growth of the Δ Flo11 mutant was significantly impaired, and the importance of Flo11 to static biofilm formation and adherence under alkaline conditions in vitro was tested.
A functional wbbL gene was introduced into the E. coli K-12 KEIO single-gene deletion mutant library to restore OAg synthesis, enabling genome-wide analysis of S-LPS production by screening with colicin E2 and validated with LPS silver staining.
These findings indicated that PABA could be a candidate inhibitor of anthranilic acid signaling to interfere with the QS systems of R. solanacearum to attenuate the virulence and presented a non-antibiotic-based treatment strategy and provided a theoretical basis for the development of novel antibacterial treatment.
The dynamic expression of UPEC's stress response mechanisms are emphasized and the central role of Bar/UvrY in modulating pathoadaptive mechanisms under antibiotic stress is outlined.
