Immunoglobulin-coated bacteria in faecal samples from untreated (white bars) and treated CD patients (grey bars) and healthy controls (black bars) as assessed by FCM. Panel A, IgA-coated bacteria; Panel B, IgG-coated bacteria; Panel C, IgM-coated bacteria. Date are expressed as a proportion of bacterial cells labelled with FITC-F(ab')2 antihuman IgA, IgG or IgM to total cell population hybridising with propidium iodine. Median values and ranges are given. *Significant differences were established at P < 0.050 by applying the Mann-Whitney U-test.
