FIG. 2.

IgG and IgM ELISA results with rFlaA proteins from B. garinii (Bg46) (A), B. afzelii (BaA91) (B), and B. burgdorferi sensu stricto (Bbia) (C) as antigens. Optical density (OD) values for each patient group and control samples are shown separately. Serum samples were from patients with EM at the acute phase (EM1), EM at the convalescent phase (EM2), NB, LA, syphilis (SY), RF positivity (RF+), ASO positivity, EBV infection, Yersinia infection (YE), and SLE and from healthy blood donors (BD). The cutoff level (mean + 2 SD of blood donor samples) for each antigen is indicated by a line.
