MOESM1 of Immune responses upon Campylobacter jejuni infection of secondary abiotic mice lacking nucleotide-oligomerization-domain-2

Additional file 1: Figure S1. Fecal blood in C. jejuni infected secondary abiotic Nod2−/− mice. Secondary abiotic wildtype (WT; white circles) and Nod2−/− mice (black circles) were generated by broad-spectrum antibiotic treatment and perorally infected with C. jejuni strain 81-176 by gavage at day (d) 0 and d1. Microscopic or macroscopic occurrence of blood in fecal samples before and after infection was assessed applying a standardized haemoccult scoring system (see methods). Absolute numbers of animals with blood-positive fecal samples out of the total number of analyzed mice are indicated (in parentheses). Data were pooled from four independent experiments.
