Enhanced adaptive immunity to 5 Burkholderia pseudomallei antigens in survivors of melioidosis, 12 weeks after acute illness, compared to healthy seronegative controls. IFNγ ELISpot assays for HIA-Bp or one of 15 Bp proteins were performed on cryopreserved PBMC from 16 seronegative controls (black squares) and 30 acute melioidosis survivors (black triangles). PBMC samples from melioidosis survivors were taken 12 weeks after acute illness. Data shown for each protein antigen is the number of spot forming cells (SFC) per 106 PBMC following subtraction of the number of SFC from culture with media alone. Error bars represent mean + SEM and statistical significance between groups was determined using the Mann Whitney test.
