Quantification of intestinal ethanolamine concentrations in the mouse colitis model. Streptomycin-pretreated mice were orally infected with the S. Typhimurium wild-type (IR715), an eutC mutant (PT100), an invA spiB mutant (SPN452), or mock-treated, as indicated below each panel. Four days after infection, the ethanolamine concentration in colonic extracts was determined by LC-MS/MS. Data represent the geometric mean of four animals ± SE. Statistical significance (P value) is indicated above the bars.
