摘要:
Fourteen Campylobacter jejuni genes-porA, cadF, omp18, dnaK, flaC, peb1, peb2, peb3, peb4, ahpC, groEL, tuF, hipO, and Cj0069-were cloned and expressed in Escherichia coli BL21. The recombinant proteins were purified on histidine (His) and glutathione S-transferase (GST) trap columns using the AKTA Explorer 100 System. Recombinant proteins were visualized using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and identified using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The antigenicities of these recombinant proteins were assessed by Western blotting and enzyme-linked immunosorbent assays with anti-C. jejuni immune rabbit sera. Four recombinant proteins, including rGST-PorA, rHis-CadF, rGST-GroEL, and rGST-TuF, demonstrated reactions with both anti-serum and preimmune serum, while rHis-DnaK, rGST-FlaC, rGST-PEB2, rGST-PEB3, rGST-PEB4, and rGST-HipO showed variable antigenicity characteristics to the anti-sera derived from different C. jejuni strains. rHis-Omp18, rHis-PEB1, and rGST-AhpC demonstrated universal and specific antigenities with the entire anti-sera panel tested in this present study, while recombinant rGST-Cj0069 and rHis-DnaK did not react with any of the anti-C. jejuni sera tested. In conclusion, rGST-AhpC may be useful as a potential serodiagnostic antigen for C. jejuni infection.
