The immune system response to Campylobacter infection.

Campylobacter may be one of the most common causes of bacterial gastroenteritis (GE) in children. It has recently been suggested that it is one of the bacterial pathogens most likely to infect immune-compromised children, and it may facilitate colonization of enteric pathogens. The immune system response was studied in 12 children with Campylobacter fetus subspecies jejuni (CBJ) infections. Serum concentrations of IgA, IgM, and IgG were analyzed using a Beckman auto-analyzer. Sera specific Ab to CBJ were tested with CBJ specific enzyme-linked immunosorbent assay (ELISA). Mitogen stimulation of lymphocytes was performed to three lectins: Con A, PWM, and PHA. The lymphocyte blast transformation to Campylobacter was studied using the Campylobacter antigen. T-cell subsets were studied using the monoclonal antibodies Leu 2, 3, and 4 (Becton Dickinson). Chemotaxis was measured in modified Boyden chambers; chemotactic stimulants were the Formyl Met Leu Phe, Campylobacter antigen virion, and E. coli 0111 B. Immunoglobulins were normal in nine cases and abnormal in two children previously diagnosed as agammaglobulinemic and one diagnosed as hypoagammaglobulinemic. Specific serum Ab level was significantly higher in the CBJ group, except in the agammaglobulinemic group. Stimulation indices to mitogens and monoclonal subset were in the normal range. The blastogenic transformation to CBJ Ag was decreased compared to normal lectins, and positive and high compared to controls. The chemotactic activity to campylobacter Ag was decreased in comparison to other stimulants. Most CBJ infections are self-limiting due to a normal immune response and collaboration of all cellular limbs. When, however, the immune response is disturbed, we may find a prolonged and complicated course of CBJ.[1]
