Project description:Investigation of gene expression level changes in Salmonella typhimurium LT2 TA100 upon exposure to C60, compared to unexposed controls. The mutations engineered into this strain make it susceptile to mutagenic compounds. The Salmonella typhimurium TA100 strain used in this study is further described in Pedersen P, Thomsen E, Stern RM. 1983. Detection by Replica Plating of False Revertant Colonies Induced in the Salmonella Mammalian Microsome Assay by Hexavalent Chromium. Environmental health perspectives 51: 227-230.

A 4 x 72K array study using total RNA recovered from triplicate cultures of Salmonella typhimurium LT2 TA100 exposed to C60 and triplicate cultures of controls that were not exposed to C60. Each 72K array measures the expression level of 4,504 genes from Salmonella typhimurium LT2 with seven 45 to 60-mer probe pairs per gene.

Project description:Salmonellosis is one of the leading health problems worldwide. With the rise of drug resistance strains it has become imperative to identify alternative strategies. Naringenin, a flavonone, is present predominantly in grapefruit. Previously we have demonstrated that naringenin is potent inhibitor of cell-cell signaling. In the present study, we provide evidence that naringenin specifically represses 24 genes in the Salmonella pathogenicity island 1, and down-regulates 17 genes involved in flagellar and motility; thereby, attenuating virulence and cell motility, respectively. This is the first molecular evidence to demonstrate effect of naringenin on bacterial virulence and cell motility. One condition experiment, naringenin treated versus DMSO treated. Biological replicates: 3 control, 3 treatment, hybridized in dye-swapped design

Project description:Investigation of whole genome gene expression level changes in a Salmonella enterica serovar Typhimurium UK1 delta-iacP mutant, compared to the wild-type strain. IacP is resoponsible for the secretion of virulence effector proteins via the type III secretion system, thereby contributing the virulence of S. Typhimurium. The mutants analyzed in this study are further described in Kim et al. 2011. Role of Salmonella Pathogenicity Island 1 Protein IacP in Salmonella enterica Serovar Typhimurium Pathogenesis. Infection and Immunity 79(4):1440-1450 (PMID 21263021).

Project description:Salmonella enterica serovar Typhimurium (S. Typhimurium) definitive phage type 104 (DT104) has caused significant morbidity and mortality in humans and animals for almost three decades. We have completed the full DNA sequence of one DT104 strain, NCTC13348 and show that the main differences between the genome of this isolate and the previously sequenced S. Typhimurium LT2 lie in integrated prophage elements and the Salmonella Genomic Island 1 encoding antibiotic resistance genes. Thirteen isolates of S. Typhimurium DT104 with different pulsed field gel electrophoresis (PFGE) profiles were analyzed by multi locus sequence typing (MLST), plasmid profiling, hybridization to a Pan-Salmonella DNA microarray and prophage-based multiplex PCR. All the isolates belonged to a single MLST type ST19. Microarray data demonstrated that the 13 DT104 isolates were remarkably conserved in gene content. The PFGE band-size differences in these isolates could be explained to a great extent by changes in prophage and plasmid content. Thus, here the nature of variation in different S. Typhimurium DT104 isolates is further defined at the genome level illustrating how this phage type is evolving over time.
