Overview of gene presence and associated IgG responses of bacterial antigens.

Presence of genes in 21 isolates, initial-to-peak fold-increases in IgG levels and comparison of peak IgG levels in 21 bacteremia patients and 30 non-infected controls for 56 staphylococcal antigens and three non-staphylococcal control antigens. Patients for whom the duplicate measurements of the IgG levels had a CV larger than 25% were excluded from the analysis. IgG levels for the antigens EsxA, PSM alpha 1–4 peptides, SA0104, SEI and SEJ were completely excluded because of very low signal intensities with coefficients of variation larger than 25% for a majority of patients. ND: not determined.
