FIG. 2.

Comparison of the sequences of the cFD2 and FS778 amplimer positions of flaviviruses according to the CLUSTAL algorithm. The program takes as input a dendrogram produced by the UPGMA method. Viruses amplified in our laboratory are shown in boldface (Table 1). Other sequences were obtained from GenBank (Table 4). The alignment allowed us to find all of the complexes of medical interest: the DEN, JE, WN, YF, TBE, and Rio Bravo groups.
