Proteins that are specifically recognized by cellular responses do not necessarily elicit serum antibodies. WBA-IFNγ secretion and serum IgG responses were assessed against the ML1632, ML1685, ML1556, ML2044 and ML0840 proteins. WBA results are presented as box plots 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).
