Phenotypic traits of coexisting epidemic and nonepidemic strains ofSalmonella enterica serovars Typhimurium and Newport were compared. Different stress conditions were relatively more or less favorable for the epidemic strains. Transcriptional analysis identified specific upregulated genes during defined stress conditions, but there were no common traits shared by epidemic serovars.
