Hypervariable region in the C. jejuni genome. (A) A genetic locus between ORFs Cj0564 and Cj0570 of reference strain NCTC 11168 shows significant variability across the sequenced strains of C. jejuni. Each of the strains shows a different genomic fragment integrated at this site. (B) PCR amplification of this region with primers complementary to sequences within conserved ORFs Cj0564 and Cj0570 yielded fragments of various sizes, an indication of the diversity of this region. The gel shows fragments amplified from 15 different clinical isolates. Amplification of DNAs from isolates 1, 3, 4, 5, 9, and 10 yielded a band of a size similar to that of C. jejuni NCTC 11168; isolates 2, 8, 11, 13, 14, and 15 yielded a band of a size similar to that of C. jejuni 81-176; and isolate 6 yielded a band of a size similar to that of C. jejuni RM1221. The lack of amplification of a DNA fragment from isolate 7 may be due to sequence diversity within the Cj0564 and Cj0570 ORFs.
