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 ...

IS200: an old and still bacterial transposon
(Springer Verlag, 2004)
IS200 is a mobile element found in a variety of eubacterial genera, such as Salmonella, Escherichia, Shigella, Vibrio, Enterococcus, Clostridium, Helicobacter, and Actinobacillus. In addition, IS200-like elements are found ...

Regulation of conjugal transfer by Lrp and dam methylation in plasmid R100
(Sociedad Española de Microbiología, 2005-12)
Conjugal transfer of the F-like plasmid R100 occurs at higher frequencies in the absence of DNA adenine methylation. Lower levels of R100-encoded FinP RNA were found in a Dam- host, suggesting that Dam methylation regulates ...

DNA adenine methylation regulates virulence gene expression in Salmonella enterica serovar typhimurium
(American Society for Microbiology, 2006)
Transcriptomic analyses during growth in Luria-Bertani medium were performed in strain SL1344 of Salmonella enterica serovar Typhimurium and in two isogenic derivatives lacking Dam methylase. More genes were repressed than ...
Artículo
Role of the RecBCD recombination pathway in Salmonella virulence
(American Society for Microbiology, 2002)
Mutants of Salmonella enterica lacking the RecBC function are avirulent in mice and unable to grow inside macrophages (N. A. Buchmeier, C. J. Lipps, M. Y. H. So, and F. Heffron, Mol. Microbiol. 7:933-936, 1993). The ...
Artículo
Roles of DNA adenine methylation in host-pathogen interactions: mismatch repair, transcriptional regulation, and more
(Oxford University Press, 2009)
The Dam methylase of gamma-proteobacteria and the CcrM methylase of alpha-proteobacteria catalyze an identical reaction (methylation of adenosine moieties using S-adenosyl-methionine as methyl donor) at similar DNA targets ...
Artículo
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 ...
Artículo
YhdJ, a nonessential CcrM-like DNA methyltransferase of Escherichia coli and Salmonella enterica
(American Society for Microbiology, 2007)
The Caulobacter crescentus DNA adenine methyltransferase CcrM and its homologs in the α-Proteobacteria are essential for viability. CcrM is 34% identical to the yhdJ gene products of Escherichia coli and Salmonella enterica. ...
