(Submitter supplied) Salmonella enterica serovar Typhimurium (S. Typhimurium) infection triggers an inflammatory response that changes the concentration of luminal metabolites in the gut, resulting in a distinct environment from a healthy one. We recently demonstrated that S. Typhimurium possesses the ability to form biofilms within the host environment and responds to nitrate as a signaling molecule, enabling it to modulate the transition between sessile and planktonic states. more...

(Submitter supplied) We present genome-wide RpoD-family sigma factors (RpoD, RpoS, and RpoH) binding profiles and transcriptome profiles in Salmonella Typhimurium 14028s under both control (37°C) and sublethal heat shock conditions (42°C). These genome-scale experimental data show how three RpoD-family sigma factors simultaneously coordinate many types of cellular processes to orchestrate the overall response of S. Typhimurium to heat stress.

(Submitter supplied) The non-typhoidal Salmonella enterica serotype Heidelberg is a major foodborne pathogen primarily transmitted to humans through contaminated poultry products. Current control measures emphasize novel approaches to mitigate Salmonella Heidelberg colonization in poultry and the contamination of poultry products, thereby reducing its transmission to humans. This study highlight that commensal E. coli 47-1826 can potentially be used to control of S. more...

(Submitter supplied) SdiA is a LuxR-type protein found in some Enterobacteriaceae. SdiA encoding bacteria do not encode a luxI homolog and rely on foreign bacteria for the production of N-acyl homoserine lactones (AHLs), SdiA's ligand. The regulon of Salmonella SdiA is largely unknown. In this study, we measured the sdiA dependent transcriptional changes of two serovars of Salmonella, Typhimurium and Typhi, exposed to synthetic AHLs. more...

(Submitter supplied) This study characterized the involvement of yihO and yihQ of yih operon associated with O-antigen capsule formation, in phenotypic characteristics, intracellular survival, and virulence in Salmonella Typhimurium (ST). Bacterial fitness screening of the ∆yihO, ∆yihQ, and ∆yihO/Q ST mutants showed impairment in biofilm formation, motility, starvation, and stress survival. In vitro studies using phagocytic and non-phagocytic cells revealed a significant decrease in bacterial invasion and intracellular replication, particularly by the ∆yihO and ∆yihO/Q ST which correlated with the lack of proliferation ability in vivo as observed in the liver and spleen colonization. more...

(Submitter supplied) We report the transcriptomic changes in Salmonella Typhimurium exposed to sub-lethal sonophotocatalytic disinfection. The current data suggests that more than 120 genes are significantly expressed during the process. The genes associated with the flagellar assembly were found to be significantly up-regulated during the disinfection, which may have impacts on the phenotypic attributes of the bacteria.

(Submitter supplied) We report the genome-wide analysis from chromatin immunoprecipitated DNA (ChIP-sequencing) of the DNA binding pattern of ParBF (SopB) of plasmid F. This study, performed in E. coli and Salmonella typhimurium, investigates the impact of DNA supercoiling on ParBF DNA binding profiles in vivo. We found that variation in DNA supercoiling does not significantly affect the ParB DNA binding profiles even on linear DNA.

(Submitter supplied) Elongation factor P (EF-P) is required to enhance peptidyl transferase on pausing ribosomes, which can be induced by certain codons on mRNA. It regulates expression of genes in specific conditions. Therefore, to search EF-P mediated ribosome stalling motif, ribosome profiling has been used on organisms such as yeast and E. coli. However, it has not been addressed on the intracellular pathogen Salmonella Typhimurium. more...

A similar growth-rate control is detected in pathogenic bacteria that infect and persist inside their hosts.

(Submitter supplied) The ability of bacteria to sense and respond to mechanical forces has important implications for pathogens during the in vivo infection process, as they experience wide fluid shear fluctuations in the host. However, relatively little is known about how mechanical forces encountered in the infected host drive microbial pathogenesis. We previously demonstrated an inverse relationship between fluid shear-induced responses of classic gastrointestinal disease-causing Salmonella Typhimurium (x3339) and systemic multidrug resistant (MDR) S. more...

(Submitter supplied) Polyamines, crucial molecules involved in cell proliferation and growth, play a pivotal role in cancer development and progression. Within the tumor microenvironment, macrophages, key components of the immune system, exhibit a complex relationship with polyamines. Evidence suggests that polyamines can modulate macrophage polarization, influencing their functional phenotypes. Here, we detected the gene DNA methylation changes in spermine-stimulated human macrophages isolated from PBMCs and TAMs.
