FIG. 5.

Western blot analysis of serum from mice infected with Borrelia species after treatment with tetracycline. (A) Reactions of serum samples from a mouse infected with B. hermsii serotype 7 against protein extract of B. hermsii serotype 7 cells. (B) Reactions of sera collected daily from a mouse infected with B. crocidurae serotype C2 and tested against protein extract of B. crocidurae serotype C2 cells. The mice were treated with tetracycline at day 2 postinfection. Numbers at the top of each panel correspond to day postinfection. The rightmost lane, marked C, includes a positive control antiserum. Molecular mass standards in kilodaltons are indicated on the right.
