Clinical significance of the percentage of IgA- and IgG-coated bacteria in feces of CD patients. IgA-, IgG-coated bacteria and IgA/IgG-coated bacteria were determined by flow cytometry, and clinical relevance of these bacteria was evaluated in respect to age, location, disease behavior and perianal lesions, respectively. a The percentage of IgA-, IgG- and IgA/IgG-coated bacteria in feces of HC (n = 41), A1 CD (n = 14), A2 CD (n = 122), and A3 CD (n = 42) patients. b The percentage of IgA-, IgG- and IgA/IgG-coated bacteria in feces of HC (n = 41), L1 CD (n = 57), L2 CD (n = 49), and L3 CD (n = 72) patients. c The percentage of IgA-, IgG- and IgA/IgG-coated bacteria in feces of HC (n = 41), B1 CD (n = 99), B2 CD (n = 65), and B3 CD (n = 14) patients. d The percentage of IgA-, IgG- and IgA/IgG-coated bacteria in feces of HC (n = 41), PCD (n = 33), and CD (n = 145). *P < 0.05, **P < 0.01
