Binding of monoclonal antibodies 364-10-9, 345-1-15, and 167-3-1 to whole-cell lysates of Campylobacter species by ELISA. Columns represent the average ± standard deviation of the average values obtained from all strains of each species tested. Each average value was originally determined from four replicate tests after subtraction of sample blank values. The number of strains tested for C. jejuni, C. coli, C. lari, C. hyointestinalis, C. upsaliensis, and C. mucosalis was 19, 6, 6, 5, 6, and 1, respectively.
