We have evaluated the ability of a new genotyping method for
Campylobacter jejuni based on restriction fragment length
polymorphisms using random chromosomal gene probes. DNAs from C. jejuni strains digested with each of three restriction enzymes,
HhaI, HaeIII, and HpaII, were
analyzed by Southern hybridization using each of two unrelated cosmid
clones, P14 and P15 (respectively containing 30- and 35-kb genomic DNA
fragments of C. jejuni strain OH4384). The method reported
provides a stable and discriminating means for identifying C. jejuni strains and should be useful for epidemiological analyses.
