Oral infection with Salmonella typhimurium SL1344 decreases the expression of Fgf15 in the ileum. (A) bacterial counts in infected ilea and livers; animals were arbitrarily grouped into low, medium and high infection levels (100-103, 104-105 and >106 cfu/mg, respectively roughly corresponding to 72, 96 and 120 hours post-infection; UI: uninfected). (B) relative levels of Fgf15 transcripts in the ilea of infected mice (data by qPCR). (C) H&E staining of ileum sections from representative uninfected and orally Salmonella-infected animals (ileal colonization of the infected animal = 2.2 × 106 cfu/mg); scale bars are 200 μm. (D) H&E staining of liver sections from representative uninfected and orally Salmonella-infected animals (liver colonization of the infected animal = 1.7 × 105 cfu/mg); scale bars are 800 and 400 μm.
