Transcriptional profile of Salmonella enterica serovars Kentucky and Enteritidis in response to acidic conditions

ABSTRACT: S. enterica sv Kentucky 3795 and S. enterica sv Enteritidis NalR were grown to mid-log phase in TSB, then subjected to three different acidic conditions generated by two different acids: HCl to pH4.5, HCl to pH5.5 and CH3COOH to pH5.5. After 10min, total RNA was harvested und compared to total RNA harvested from identical control cultures grown in TSB without the pH alteration.

Transcriptional profile of Salmonella enterica serovars Kentucky and Enteritidis in response to acidic conditions

Project description:S. enterica sv Kentucky 3795 and S. enterica sv Enteritidis NalR were grown to mid-log phase in TSB, then subjected to three different acidic conditions generated by two different acids: HCl to pH4.5, HCl to pH5.5 and CH3COOH to pH5.5. After 10min, total RNA was harvested und compared to total RNA harvested from identical control cultures grown in TSB without the pH alteration. At least three biological replicates were performed for each strain and acidic condition. Total RNAs were harvested, and labeled by the conventional protocol of Brown et al, then hybridized onto a Salmonella-specific PCR product array that covered over 97% of the Enteritidis genome.

Characterisation of Modular Reponse of non-pathogenic E.coli O157 Sakai Response to acid adaptation

Project description:To study the dynamics of acid adaptation in E.coli at pH5.5 as opposed to that at pH7, samples were collected from a steady-state system for transcriptomics. Keywords: time course Single channel hybridisation were carried out using cy5 dye. Samples were collected from steady state system at pH7 and pH5.5 for 2.5h at 0min, 10min, 30min, 1h, 1.5h, 2h, 2.5h

Salmonella enterica serovar Typhimurium SL1344 cells: wildtype vs. ΔfabR mutant

Project description:Transcriptional profiling of Salmonella enterica serovar Typhimurium SL1344 cells comparing wildtype with ΔfabR mutant. Salmonella strains were cultured under free-living TSB conditions (TSB 1/20, 200 rpm, 25 °C) for 6h (ca. 2 x 108 cells/ml).
