FIG. 3.

Immunoblots with serum samples from the three relapsing fever patients from southern British Columbia tested with lysates of B. hermsii originating from the same patients. (A) Serum from patient 3 collected 10 days after onset; (B) serum from patient 2 collected 22 days after onset; (C) serum from patient 1 collected 33 days after onset. All samples were tested at a 1:100 dilution, and bound antibody was detected by ¹²⁵I-labeled protein A radiography. Antibody to GlpQ, 39 kDa, is indicated on the left, and estimated molecular masses are given on the right.
