✦ Synopsis
Since the respective undigested and intact chromosomal DNAs from C. coli JCM2529', from two strains of C. coli, C.,jejuni JCM2013 and from two strains of C.,jejuni migrated as fragments of around 1,900 kb and the chromosomal DNAs from C. luri JCM2530T and from eleven strains of C. lari migrated as fragments of around 1,640 kb, pulsed-field gel electrophoresis (PFGE) was clearly demonstrated to be useful for the discrimination of C. luri from two other thermophilic species of Campylobacter (C. coli and C. jejuni). PFGE revealed that SmuI generated nine distinctly different and distinguishable banding profiles from the DNA of 18 strains of C. lari, which included the type strain. Thrcc types of banding profile, namely, A, B and C, exemplified by the nine profiles included those from five, four and three strains of C. lari, respectively. Our present attempt to discriminate and to genome-type C. lari at the chromosomal genomic level using PFGE and SmuI may be a valuable step towards a discriminative and molecular-epidemiologic study of C. /mi.
