Transcriptomic profiling of Salmonella Typhimurium upon desiccation on stainless steel and subsequent rehydration

Transcriptional profiles of Salmonella Typhimurium str. ST4/74 air-dried onto stainless steel for 4 h was compared to an early stationary phase (ESP) culture control. Cells that had been air-dried for 4 h were then subsequently rehydrated with water for a 30 min period, after which the transcriptional profile was compared to an ESP control. Carried out using 2 biological replicates for each sample; hybridised in a two-channel hybridization against Salmonella genomic DNA as the comparator/reference.
