Current serologic Lyme disease tests use whole borrelia cells as
the source of antigen. These assays are difficult to
standardize and to optimize for sensitivity and specificity. To help
solve these problems, we constructed a library of recombinant chimeric proteins composed of portions of key antigens of Borrelia
burgdorferi. These proteins were then used to develop an
enzyme-linked immunosorbent assay. We compared our assay with the most
sensitive of three whole-cell borrelia assays. We found that the
recombinant assay could detect antibodies significantly better from
early Lyme disease sera (P < 0.05), and had the same
sensitivity for late Lyme disease sera, as the most sensitive
whole-cell borrelia assay. On potentially cross-reactive sera, the
recombinant assay was more specific, but not significantly so, than
the best whole-cell borrelia assay. Optimization of the recombinant
assay offers the potential for a significant improvement in both
sensitivity and specificity.
