FIG. 3.

Alignment of the A. centrale MSP-2 hypervariable regions between clones from two sequential persistent rickettsemic peaks. Peak 1-1 and peak 2-1 each represent a single MSP-2 type from, respectively, the first or second persistent rickettsemic cycle of vaccinate 429. Sequences are aligned starting from amino acid position 126 and extending to position 326 for peak 1-1 and to position 333 for peak 2-1. The amino acid identity and substitutions, insertions, and deletions are indicated as in Fig. 1A.
