A subset of TbF6-DPEP-positive sera was assayed with the recombinant antigens and lysate to demonstrate the restricted reactivity of some sera to discrete antigens. Values in italic and boldface type represent sera positive for a particular antigen. Boldface numbers outline examples of sera that are restricted in some cases to an individual antigen.
