Influence of Microbial and Host Cell Sublethal Heat Stress on S. Typhimurium Gene Expression

(Submitter supplied) Environmental stress contributes to the outcome of infection by impacting both microbial virulence and host susceptibility to infection. Thermal processing, commonly used for decontamination of poultry in the food industry, may elicit sublethal stress on resistant serovars of Salmonella. We employed traditional heat shock temperatures (42 and 48ºC), similar to avian body temperature and poultry processing conditions, to study gene expression of Salmonella enterica serovar Typhimurium. more...

Salmonella typhimurium LT2 1.1K

(Submitter supplied) Using the transcriptome of Salmonella Typhimurium LT2, an oligonucleotide microarray, made up of 43-45 mers, was designed. We choose 1152 genes, that were selected based upon their being associated with virulence or with regulation of virulence genes. Specifications of oligos were based upon various design characteristics such as temperature of melting, 3’ location, specificity, lack of repeat nucleotides, and other consideration as previously described. more...
