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 ...

Regulation of finP transcription by DNA adenine methylation in the virulence plasmid of Salmonella enterica
(American Society for Microbiology, 2005-08)
DNA adenine methylase (Dam -) mutants of Salmonella enterica serovar Typhimurium contain reduced levels of FinP RNA encoded on the virulence plasmid. Dam methylation appears to regulate finP transcription, rather than FinP ...

Copy Number Heterogeneity in the Virulence Plasmid of Salmonella enterica
(Frontiers Media, 2020)
Quantitative PCR analysis shows that the virulence plasmid of Salmonella enterica serovar Typhimurium (pSLT) is a low-copy-number plasmid, with 1–2 copies per chromosome. However, fluorescence microscopy observation of ...

Regulation of the Salmonella enterica std fimbrial operon by DNA adenine methylation, SeqA, and HdfR
(American Society for Microbiology, 2008)
DNA adenine methylase (dam) mutants of Salmonella enterica serovar Typhimurium grown under laboratory conditions express the std fimbrial operon, which is tightly repressed in the wild type. Here, we show that uncontrolled ...
