Salmonella enterica serovar Typhimurium is a primary enteric pathogen infecting both
humans and animals. Infection begins with the ingestion of contaminated food or water so …

▪ Abstract Virulence factors of pathogenic bacteria (adhesins, toxins, invasins, protein
secretion systems, iron uptake systems, and others) may be encoded by particular regions of …

The small RNAs associated with the protein Hfq constitute one of the largest classes of post‐
transcriptional regulators known to date. Most previously investigated members of this class …

Salmonella enterica serovar Typhimurium is arguably the world's best-understood bacterial
pathogen. However, crucial details about the genetic programs used by the bacterium to …

Salmonella typhimurium causes enteric and systemic disease by invading the intestinal
epithelium of the distal ileum, a process requiring the invasion genes of Salmonella …

Invasion of intestinal epithelial cells by Salmonella enterica is decreased after exposure to
butyric acid. To understand the molecular mechanisms of this phenomenon, a comparative …

ABSTRACT Salmonella pathogenicity island 2 (SPI-2) encodes a putative, two-component
regulatory system, SsrA-SsrB, which regulates a type III secretion system needed for …

Virulence factors generally enhance a pathogen's fitness and thereby foster transmission.
However, most studies of pathogen fitness have been performed by averaging the …

Salmonella pathogenicity island 1 (SPI1) encodes a type III secretion system that is required
for virulence during the intestinal phase of infection. The expression of SPI1 genes is …

Salmonella enterica serovar Typhimurium invades intestinal epithelial cells using a type
three secretion system (TTSS) encoded on Salmonella Pathogenicity Island 1 (SPI1). The …
