Fecal microbiota composition in conventionally colonized mice following oral ileitis microbiota transplantation right before C. jejuni infection. Four days following oral transplantation of ileitis microbiota (TX, open circles; n = 10 mice) into conventional mice and right before oral C. jejuni ATCC 43431 infection, fecal samples were obtained to quantitatively assess E. coli (Ec), Enterococcus spp. (En), Lactobacillus spp. (Lb), Bacteroides/Prevotella spp. (B/P), Clostridium/Eubacterium spp. (C/E), as well as total bacterial loads (TL) by detection of colony forming units (CFU) per mL on appropriate culture media (see Materials and methods) and compared to conventional mice with beginning acute ileitis 4 days following T. gondii infection (ILE, solid circles; n = 10). Medians (black bars) and levels of significance (p-values) as determined by the Mann–Whitney U test are indicated. Data shown are representative for three independent experiments
