proteins that lack specificity. The proteins ML0022, ML2358, ML2346, ML2380, ML2541, ML2603 and ML2203 were immunogenic but not specific. WBA results are presented as box and whisker plots, with the boxes encompassing the 25th and 75th percentiles, and the black line within each box indicating the median value, n = 20 per group. Antibody results are shown in scatter plots of individual values for each individual serum tested, n = 45 per group. The dotted line indicates the calculated cut-off for positive responses (OD >0.3).
