FIG. 1.
Schematic representation of the flagellin gene loci of V. cholerae. Genes are designated by open boxes, and arrows indicate the direction of transcription. PCR-derived fragments used to sequence the flaAC locus (see Materials and Methods) are indicated by lines. Below each gene, the percent amino acid identity to the corresponding gene of V. anguillarum is indicated. The tnpA gene lies within an insertion sequence element, IS1004, which has been described only in V. cholerae (4).
