Reactivities of sera from patients at different stages of syphilis to the recombinant T. pallidum proteins. The y axis shows the mean ELISA absorbance values at 600 nm for each serum sample from individuals with syphilis tested with each recombinant protein. The sera on the x axis are grouped by stage of syphilis: P, primary (n = 14); S, secondary (n = 13); L, latent (n = 8); and N, neurosyphilis (n = 8). The overall mean absorbance of each group is represented by a horizontal line.
