FIG 2.
Intestinal inflammation induced by ETEC strain H10407 infection in antibiotic-pretreated mice fed a nourished diet (HC), a protein-deficient diet (dPD), or a zinc-deficient diet (dZD). Protein extracts were obtained from fecal samples at day 2 postinfection by lysing fecal specimens in RIPA buffer. Supernatants from the lysates were used for protein quantification and specific ELISAs for evaluation of myeloperoxidase (MPO) or lipocalin (LCN-2). (A) LCN-2 fecal levels after infection. *, P < 0.05 (dZD versus dZD plus ETEC and dPD versus dPD plus ETEC). (B) MPO fecal levels after infection. *, P < 0.05 (HC versus HC plus ETEC and dPD versus dPD plus ETEC); **, P < 0.01 (dZD versus dZD plus ETEC) (n = 8/group).
