Acid glycine extracts from four Campylobacter pylori strains and one GCLO strain were used as antigens in enzyme immunoassay (EIA). Immune responses of rabbits immunized with C. pylori strains, the GCLO-strain and other campylobacter strains were studied. All 14 rabbit antisera against C. pylori reacted with all four C. pylori extracts and there were extensive cross-reactions between these extracts. Antisera against C. jejuni and C. coli strains did not react with a C. pylori extract but reached with the GCLO antigen. Acid glycine extracts proved to be very satisfactory in C. pylori serology and the use of an extract prepared from only one strain instead of a combination of strains seems justified.
