Acetylation Regulating Protein Stability and DNA-Binding Ability of HilD, thus Modulating Salmonella Typhimurium Virulence

Serovar Typhimurium Salmonella enterica Virulence Regulatory Proteins of DNA-Binding Activities of the HilC and HilD

Isolation and Detection of Virulence factors of Salmonella typhimurium and Salmonella enteritidis

Plasmids play an important role in the virulence and antibiotic resistance of Salmonella. Salmonella carry plasmids having different size and number. Plasmid profile analysis of single isolates of Salmonella typhimurium and Salmonella enteritidis revealed the presence of 4- plasmid profiles. Salmonella serovars produce several Type III secretions including Sop-E and Sop –B. Soap E is detected b...

The Salmonella Spi1 virulence regulatory protein HilD directly activates transcription of the flagellar master operon flhDC.

Infection of intestinal epithelial cells is dependent on the Salmonella enterica serovar Typhimurium pathogenicity island 1 (Spi1)-encoded type III injectisome system and flagellar motility. Thus, the expression of virulence and flagellar genes is subject to tight regulatory control mechanisms in order to ensure the correct spatiotemporal production of the respective gene products. In this work...

Virulence of a Salmonella typhimurium OmpD mutant.

An ompD mutation caused by a Tn10 insertion was transduced into Salmonella typhimurium SL1344 and UK-1. The adherence and invasion capabilities of the resultant ompD mutants were examined by tissue culture analysis. The virulence of the S. typhimurium ompD mutants was ascertained by a 50% lethal dose (LD50) study and by determining colonization ability with BALB/c mice. We found no statisticall...
