Conjugal transfer of the Salmonella enterica virulence plasmid in the mouse intestine
(American Society for Microbiology, 2008)
BALB/c mice were infected with two Salmonella enterica serovar Typhimurium strains, one of which lacked the virulence plasmid. Transconjugants were found at high frequencies in the mouse feces and at low frequencies in the ...

Roles of the outer membrane protein asmA of Salmonella enterica in the control of marRAB expression and invasion of epithelial cells
(American Society for Microbiology, 2009)
A genetic screen for suppressors of bile sensitivity in DNA adenine methylase (dam) mutants of Salmonella enterica serovar Typhimurium yielded insertions in an uncharacterized locus homologous to the Escherichia coli asmA ...

Regulation of igaA and the rcs system by the mvia response regulator in salmonella enterica
(American Society for Microbiology, 2009)
IgaA is a membrane protein that prevents overactivation of the Rcs regulatory system in enteric bacteria. Here we provide evidence that igaA is the first gene in a 70-dependent operon of Salmonella enterica serovar Typhimurium ...

The GATC-binding protein SeqA is required for bile resistance and virulence in Salmonella enterica serovar Typhimurium
(American Society for Microbiology, 2007)
Disruption of the seqA gene of Salmonella enterica serovar Typhimurium causes defects similar to those described in E. coli: filament formation, aberrant nucleoid segregation, induction of the SOS response, envelope ...

Salmonella type III secretion effector SlrP is an E3 ubiquitin ligase for mammalian thioredoxin
(Elsevier, 2009)
Salmonella enterica encodes two virulence-related type III secretion systems in Salmonella pathogenicity islands 1 and 2, respectively. These systems mediate the translocation of protein effectors into the eukaryotic host ...

Bile-induced curing of the virulence plasmid in Salmonella enterica serovar typhimurium
(American Society for Microbiology, 2006)
Exposure to bile induces curing of the virulence plasmid in Salmonella enterica serovar Typhimurium (pSLT). Disruption of the ccdB gene increases pSLT curing, both spontaneous and induced by bile, suggesting that the pSLT ...
Artículo
Rcs and PhoPQ regulatory overlap in the control of Salmonella enterica virulence
(Journal of Bacteriology, 2007)
Genetic screens based on the use of MudJ-generated lac fusions permitted the identification of novel genes regulated by the Rcs signal transduction system in Salmonella enterica serovar Typhimurium. Besides genes that are ...

Role for Salmonella enterica enterobacterial common antigen in bile resistance and virulence
(American Society for Microbiology, 2003)
Passage through the digestive tract exposes Salmonella enterica to high concentrations of bile salts, powerful detergents that disrupt biological membranes. Mutations in the wecD or wecA gene, both of which are involved ...
