Std fimbriae-fucose interaction increases Salmonella-induced intestinal inflammation and prolongs colonization
(PLOS, 2019)
Expression of ABO and Lewis histo-blood group antigens by the gastrointestinal epithelium is governed by an α-1,2-fucosyltransferase enzyme encoded by the Fut2 gene. Alterations in mucin glycosylation have been associated ...

The yeast HPR1 gene has a functional role in transcriptional elongation that uncovers a novel source of genome instability
(Cold Spring Harbor Laboratory Press, 1997)
The yeast HPR1 gene plays an important role in genome stability, as indicated by the observation that hpr1 mutants have high frequencies of DNA repeat recombination and chromosome loss. Here we report that HPR1 is required ...

Genome expression analysis of nonproliferating intracellular Salmonella enterica serovar ty phimurium unravels an acid pH-dependent PhoP-PhoQ response essential for dormancy
(American Society for Microbiology, 2013-01)
Genome-wide expression analyses have provided clues on how Salmonella proliferates inside cultured macrophages and epithelial cells. However, in vivo studies show that Salmonella does not replicate massively within host ...

Comparative genomics of citric-acid-producing Aspergillus niger ATCC 1015 versus enzyme-producing CBS 513.88
(Cold Spring Harbor Laboratory Press, 2011)
The filamentous fungus Aspergillus niger exhibits great diversity in its phenotype. It is found globally, both as marine and terrestrial strains, produces both organic acids and hydrolytic enzymes in high amounts, and some ...

Smc5–Smc6 mediate DNA double-strand-break repair by promoting sister-chromatid recombination
(Nature Publishing Group, 2006)
DNA double-strand breaks (DSB) can arise during DNA replication, or after exposure to DNA-damaging agents, and their correct repair is fundamental for cell survival and genomic stability. Here, we show that the Smc5–Smc6 ...

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 ...

Epigenetic biosensors for bacteriophage detection and phage receptor discrimination
(Society for Applied Microbiology, 2020)
Environmental monitoring of bacteria using phage-based biosensors has been widely developed for many different species. However, there are only a few available methods to detect specific bacteriophages in raw environmental ...
