FIG. 3.

Comparison of sapA-pspF intergenic region DNA sequences from Y. enterocolitica strains JB580v (serotype O:8, ytxAB⁺) and MC7 (serotype O:9, no ytxAB locus). Only part of each intergenic region is shown. The DNA sequence in boldface type is unique to strain JB580v (ytxAB gene sequences were omitted for clarity). Bullets above the sequences indicate differences between the regions conserved in both strains. The ytxA start codon, ytxB stop codon, and pspF stop codon (complementary strand) are labeled and underlined.
