Biol Res
. 2022 Feb;
55(1):8.
PMID: 35193678
Background: Salmonella Typhimurium is a Gram-negative pathogen that causes a systemic disease in mice resembling typhoid fever. During its infective cycle, S. Typhimurium is phagocytized by macrophages and proliferates inside...

PMID: 25913156
The difference in host range between Salmonella enterica serovar Typhimurium (S. Typhimurium) and S. enterica serovar Typhi (S. Typhi) can be partially attributed to pseudogenes. Pseudogenes are genomic segments homologous...

Microbiology (Reading)
. 2013 Aug;
159(Pt 10):2049-2057.
PMID: 23918818
In response to antibiotics, bacteria activate regulatory systems that control the expression of genes that participate in detoxifying these compounds, like multidrug efflux systems. We previously demonstrated that the BaeSR...

. 2013 Feb;
159(Pt 4):715-725.
PMID: 23393149
OmpW is a minor porin whose biological function has not been clearly defined. Evidence obtained in our laboratory indicates that in Salmonella enterica serovar Typhimurium the expression of OmpW is...

Arch Microbiol
. 2012 Jul;
194(11):933-42.
PMID: 22752112
To survive, Salmonella enterica serovar Typhimurium (S. Typhimurium) must sense signals found in phagocytic cells and modulate gene expression. In the present work, we evaluated the expression and cross-regulation of...

Arch Microbiol
. 2011 Dec;
194(6):453-60.
PMID: 22173828
Two-component systems are one of the most prevalent mechanisms by which bacteria sense, respond and adapt to changes in their environment. The activation of a sensor histidine kinase leads to...

157(Pt 3):636-647.
PMID: 21148209
Salmonella enterica serovar Typhi (S. Typhi) is the aetiological agent of typhoid fever in humans. This bacterium is also able to persist in its host, causing a chronic disease by...
