FIG. 1.

Electrophoretic analysis of MLVA fragments from different B. anthracis isolates. Fluorescent image of an ABI377 electrophoresis gel containing amplification products from 45 different B. anthracis isolates. All eight VNTR loci are present in each lane. Each marker allele is a unique size and color combination, allowing easy identification of similar-sized fragments from different alleles. The 48 isolates were chosen randomly from the worldwide diversity set shown in Table 1. Sizes are shown in bases.
