Kinetic survey of fecal bacterial shedding in perorally infected gnotobiotic IL-10^-/- mice.

<p>Gnotobiotic IL-10^-/- mice were generated by antibiotic treatment and perorally colonized either with (<b>A</b>) a commensal <i>E</i>. <i>coli</i> strain, <b>(B)</b> <i>A</i>. <i>butzleri</i> strain C1, (<b>C</b>) <i>A</i>. <i>butzleri</i> strain CCUG 30485 or <b>(D)</b> <i>C</i>. <i>jejuni</i> strain 81-176 at day 0 and day 1 by gavage. Bacterial loads were determined in fecal samples (CFU / g, colony forming units per gram) over six days (d) post infection (p.i.) by culture. Medians (black bars) are indicated.
