Figure 1 Representative gels of nested PCR results of MAP-specific IS900 DNA in blood samples. (A) Controls. (B) Patients. M, molecular weight marker (1 Kb ladder; New England Biolabs, Ipswich, MA, USA); lane 1, negative control of first round PCR; lane 2, negative control of second round PCR; lanes 3–17 controls (A) or IBD (B); lane 18, positive control DNA from MAP strain ATCC 19698.

Figure 2 Humoral and cellular immune response. Relative increment and p-values (in parentheses) of the IBD group over the control group for mean absorbed antibody ELISA (ABMAP), IFN-γ in blood stimulated with MAP antigen (IFNMAP), or unstimulated (IFNPBS) and frequency of PCR-positive individuals. Positive values mean that the IBD group had higher means or frequencies than the controls and negative ones that they were lower.
