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 ...

Analysis of Salmonella lineage-specific traits upon cell sorting
(Frontiers Media SA, 2023-03-29)
Microbial cell individuality is receiving increasing interest in the scientific community. Individual cells within clonal populations exhibit noticeable phenotypic heterogeneity. The advent of fluorescent protein technology ...

Molybdenum cofactor (chlorate-resistant) mutants of Klebsiella pneumoniae M5al can use hypoxanthine as the sole nitrogen source.
(American Society for Microbiology, 1992)
Selection for chlorate resistance yields mol (formerly chl) mutants with defects in molybdenum cofactor synthesis. Complementation and genetic mapping analyses indicated that the Klebsiella pneumoniae mol genes are ...

Contribution of phenotypic heterogeneity to adaptive antibiotic resistance
(2014)
Antibiotic-resistant isolates of Salmonella enterica were selected on plates containing lethal concentrations of rifampicin, kanamycin, and nalidixic acid. The stability of the resistance phenotype was scored after ...

A eukaryotic-like 3′ untranslated region in Salmonella enterica hilD mRNA
(Oxford University Press, 2014)
Long 3' untranslated regions (3'UTRs) are common in eukaryotic mRNAs. In contrast, long 3'UTRs are rare in bacteria, and have not been characterized in detail. We describe a 3'UTR of 310 nucleotides in hilD mRNA, a transcript ...

STM2209-STM2208 (opvAB): A Phase Variation Locus of Salmonella enterica Involved in Control of O-Antigen Chain Length
(Public Library of Science, 2012)
STM2209 and STM2208 are contiguous loci annotated as putative protein-coding genes in the chromosome of Salmonella enterica. Lack of homologs in related Enterobacteria and low G+C content suggest that S. enterica may have ...

Adaptation of Salmonella enterica to bile: essential role of AcrAB-mediated efflux
(Society for Applied Microbiology, 2018)
Adaptation to bile is the ability to endure the lethal effects of bile salts after growth on sublethal concentrations. Surveys of adaptation to bile in Salmonella enterica ser. Tyhimurium reveal that active efflux is ...
